From 55e581bab9b600e7c070ec596d3109fc897d2d86 Mon Sep 17 00:00:00 2001 From: tanaka takashi Date: Tue, 1 Sep 2026 20:10:20 +0900 Subject: feat: Firefox selection translation extension with local Ollama (initial version) Implement the complete initial version of a Firefox WebExtension (Manifest V3) that translates selected text on web pages using a local Ollama LLM and shows the result in a small popover near the selection. Specification alignment (Phase 0) - Unified Specifications.md / Design.md / Security.md on the same approach: Ollama REST API + Fetch API + NDJSON streaming (no ollama-js SDK dependency) - Fixed host_permissions to http://localhost/* and http://127.0.0.1/* because Firefox match patterns do not support port numbers (bug 1362809/1468162); the actual connection target is restricted to localhost/127.0.0.1 + any port by application-side validation (defense in depth, OLL-09) - Clipboard: use navigator.clipboard.writeText() only inside the copy button click (user activation); no deprecated execCommand fallback Implementation (zero dependencies, vanilla JS, no npm/Node required) - manifest.json: MV3, background.scripts + type:module (event page, no service_worker), action popup, options_ui, content_scripts for http/https, permissions: storage + localhost host permissions only - src/shared: constants (ports, limits, presets, error codes), message validation, settings schema (defaults / merge / sanitize / buildOptions / toApiThinking), system prompt builder (fixed prompt first + user prompt) - src/background: message-router (runtime.Port streaming + runtime.onMessage for model list), translation-session (single active request, abort previous on new request, stale chunk suppression), ollama-client (fetch against /api/tags and /api/chat with buffering NDJSON line parser tolerant to chunk boundaries inside JSON objects, AbortController, host re-validation before every request, HTTP status to error-code mapping), settings-service (storage.local load/save with validation and fallback to defaults) - src/content/content.js: single classic script (Firefox does not support ES modules in content scripts) with selection detection (selectionchange + mouseup + keyup, debounced), Shadow DOM action button, Shadow DOM popover with HIDDEN/LOADING/STREAMING/COMPLETED/ERROR state machine, port client with requestId-based stale chunk filtering, enabled-state sync via storage.onChanged; all dynamic text rendered via textContent only - src/popup + src/options: full settings UI (enable toggle, Ollama host, model list from Ollama with saved-model warning, target language, thinking mode, temperature slider 0.0-2.0 step 0.1, context length presets 4k/8k/16k/32k/128k/256k, seed random/fixed with integer value, user system prompt, advanced numeric options with steppers, stop sequences textarea) - icons generated by tools/make-icons.ps1 (System.Drawing, no external tools) - build.ps1 packages manifest.json + icons/ + src/ into dist zip, excluding tests/, doc/, ollama-js/ and tools/ Tests (71 passed, 0 failed) - In-browser test runner (tests/test.html) with custom describe/it/assert framework; no npm, no Node.js - Unit: constants sync between content mirror and shared module, Ollama host validation (localhost/127.0.0.1 + any port only; rejects external hosts, LAN IPs, https, credentials, paths), settings schema defaults and fallback, temperature 0.1-step validation, context length presets, seed modes, advanced option types, buildOptions omission of unset values and absence of tfs_z/mirostat fields, system prompt composition order, message validation with selection length boundary values - Integration: NDJSON streaming across awkward byte boundaries, thinking chunk forwarding, malformed line tolerance, error payload mapping, think/ options inclusion rules, model list, TranslationSession abort semantics, settings round-trip with storage.onChanged cache refresh, full port flow (started/chunk/completed), newer request aborts older with stale chunk discard, malformed message rejection, OLLAMA_UNAVAILABLE and INVALID_SETTINGS error paths, untrusted sender rejection Security audit (Design.md section 24 checklist: all pass) - No innerHTML/outerHTML/document.write/eval/new Function/localStorage - No remote JS/CSS/fonts/CDN resources; no inline scripts in extension pages - Ollama access limited to background; content scripts never fetch Ollama - Background validates message type/length/requestId; single concurrent translation enforced - Clipboard API only (no execCommand fallback) - Minimal permissions: storage + localhost host permissions Docs - README.md with build/load/usage instructions, API list, permission rationale - doc/Testing-Results.md with automated test results, security audit results, and a 14-item manual Firefox verification checklist (to be executed on a real Firefox + Ollama environment) --- .gitignore | 31 ++ README.md | 93 ++++ build.ps1 | 36 ++ doc/Design.md | 871 ++++++++++++++++++++++++++++++++++ doc/Security.md | 804 +++++++++++++++++++++++++++++++ doc/Specifications.md | 391 +++++++++++++++ doc/Testing-Results.md | 87 ++++ icons/icon-48.png | Bin 0 -> 1013 bytes icons/icon-96.png | Bin 0 -> 1800 bytes manifest.json | 44 ++ src/background/index.js | 19 + src/background/message-router.js | 177 +++++++ src/background/ollama-client.js | 194 ++++++++ src/background/settings-service.js | 82 ++++ src/background/translation-session.js | 76 +++ src/content/content.css | 10 + src/content/content.js | 676 ++++++++++++++++++++++++++ src/options/options.css | 143 ++++++ src/options/options.html | 104 ++++ src/options/options.js | 250 ++++++++++ src/popup/popup.css | 77 +++ src/popup/popup.html | 34 ++ src/popup/popup.js | 134 ++++++ src/shared/constants.js | 71 +++ src/shared/messages.js | 69 +++ src/shared/prompt.js | 62 +++ src/shared/settings-schema.js | 311 ++++++++++++ tests/all-tests.js | 790 ++++++++++++++++++++++++++++++ tests/content-constants.js | 28 ++ tests/mocks.js | 126 +++++ tests/runner.js | 128 +++++ tests/test.html | 29 ++ tools/make-icons.ps1 | 43 ++ 33 files changed, 5990 insertions(+) create mode 100644 .gitignore create mode 100644 README.md create mode 100644 build.ps1 create mode 100644 doc/Design.md create mode 100644 doc/Security.md create mode 100644 doc/Specifications.md create mode 100644 doc/Testing-Results.md create mode 100644 icons/icon-48.png create mode 100644 icons/icon-96.png create mode 100644 manifest.json create mode 100644 src/background/index.js create mode 100644 src/background/message-router.js create mode 100644 src/background/ollama-client.js create mode 100644 src/background/settings-service.js create mode 100644 src/background/translation-session.js create mode 100644 src/content/content.css create mode 100644 src/content/content.js create mode 100644 src/options/options.css create mode 100644 src/options/options.html create mode 100644 src/options/options.js create mode 100644 src/popup/popup.css create mode 100644 src/popup/popup.html create mode 100644 src/popup/popup.js create mode 100644 src/shared/constants.js create mode 100644 src/shared/messages.js create mode 100644 src/shared/prompt.js create mode 100644 src/shared/settings-schema.js create mode 100644 tests/all-tests.js create mode 100644 tests/content-constants.js create mode 100644 tests/mocks.js create mode 100644 tests/runner.js create mode 100644 tests/test.html create mode 100644 tools/make-icons.ps1 diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..17fe286 --- /dev/null +++ b/.gitignore @@ -0,0 +1,31 @@ +# Build output +dist/ + +# Reference repository (cloned for API shape reference only;

Dependency Policy + +### 3.1 Mandatory Rules + +The project MUST be developed without Node.js or JavaScript package managers. + +The following are prohibited: + +- Node.js as a required development or runtime dependency +- npm +- yarn +- pnpm +- bun package management +- `node_modules` +- third-party JavaScript packages +- third-party CSS frameworks +- remote JavaScript +- remote CSS +- remote fonts +- CDN-hosted runtime resources + +The project SHOULD NOT contain `package.json`. + +All resources required at runtime MUST be included directly in the extension package or supplied by Firefox/Web Platform standard APIs. + +### 3.2 Allowed Technologies + +The implementation MAY use: + +- HTML +- locally stored CSS +- vanilla JavaScript +- Firefox WebExtensions APIs +- standard DOM APIs +- Fetch API +- Streams API +- `TextDecoder` / `TextDecoderStream` +- standard `JSON` APIs +- locally bundled PNG/SVG assets +- inline SVG created by the project +- operating-system fonts through CSS generic/system font families + +### 3.3 CSS and Asset Policy + +All application CSS MUST be owned by this project and stored locally in the repository. + +Do not download and vendor a CSS framework unless explicitly approved. + +Preferred approach: + +```text +content.css +popup.css +options.css +``` + +External resources such as the following MUST NOT be used: + +```text +Google Fonts +Font Awesome CDN +Material Icons CDN +Bootstrap CDN +Tailwind CDN +jsDelivr +unpkg +cdnjs +``` + +Icons SHOULD be: + +1. project-owned local SVG/PNG files, or +2. inline SVG defined directly by the application. + +System fonts SHOULD be used, for example: + +```css +font-family: system-ui, sans-serif; +``` + +--- + +## 4. Ollama Integration Policy + +### 4.1 No Ollama JavaScript SDK Dependency + +The project MUST NOT require `ollama-js`. + +The extension MUST communicate with Ollama directly using the official Ollama HTTP API and the browser Fetch API. + +The intent is to eliminate npm/package-manager supply-chain dependencies. + +### 4.2 Required API Scope + +The initial implementation SHOULD require only the minimum Ollama endpoints needed by the specification. + +Expected endpoints: + +| Endpoint | Purpose | +|---|---| +| `GET /api/tags` | Retrieve installed models. | +| `POST /api/chat` | Perform translation generation using streaming. | + +Do not add Ollama API endpoints unless required by a defined feature. + +### 4.3 Streaming + +Translation MUST use streaming responses. + +The Ollama client module MUST: + +- parse streamed response data safely; +- tolerate chunk boundaries that do not align with JSON object boundaries; +- cancel the current request when a newer translation request supersedes it; +- use `AbortController` or equivalent standard browser functionality; +- propagate only validated translation text to the content script. + +### 4.4 Ollama Endpoint + +Default endpoint: + +```text +http://localhost:11434 +``` + +The endpoint MAY be configurable according to the product specification. In the initial version, the configured endpoint MUST be limited to `http://localhost:` or `http://127.0.0.1:`. External hosts, LAN IPs, and HTTPS endpoints MUST be rejected by validation. + +The implementation MUST validate the configured value before use, and the Ollama client MUST re-verify the target host immediately before each request (defense in depth). + +The background component MUST be the only component that communicates directly with Ollama. + +Content scripts MUST NOT directly call Ollama. + +--- + +## 5. Firefox WebExtensions Policy + +### 5.1 Manifest + +The extension MUST use Manifest V3. + +Firefox-specific behavior MUST be verified against current MDN documentation before implementation. + +Do not blindly copy Chromium-specific Manifest V3 examples. + +### 5.2 Background Implementation + +For Firefox, use the supported background mechanism documented for Firefox. + +Do NOT assume Chromium's: + +```json +"background": { + "service_worker": "background.js" +} +``` + +is supported by Firefox. + +The implementation agent MUST verify the current Firefox support status before changing the background model. + +### 5.3 APIs to Prefer + +Use modern APIs where required: + +| Purpose | Preferred API | +|---|---| +| Toolbar action | `action` | +| Extension storage | `storage.local` | +| Long-lived extension communication | `runtime.connect()` / `runtime.Port` | +| One-shot extension messages | `runtime.sendMessage()` | +| Dynamic script injection, only if needed | `scripting.executeScript()` | + +### 5.4 APIs / Patterns to Avoid + +Do not introduce the following unless explicit project requirements justify them: + +- Manifest V2 +- `browser_action` +- `browserAction.*` +- `tabs.executeScript()` +- `tabs.insertCSS()` +- `runtime.getBackgroundPage()` +- `extension.getBackgroundPage()` +- `window.localStorage` for extension settings +- `externally_connectable` +- `runtime.onMessageExternal` +- `runtime.onConnectExternal` +- `nativeMessaging` +- `webRequest` +- `cookies` +- `history` +- `bookmarks` +- `downloads` +- unnecessary `tabs` permission +- unnecessary `scripting` permission + +The implementation MUST verify whether any WebExtensions API it intends to add is deprecated, obsolete, Firefox-incompatible, or unnecessarily privileged. + +--- + +## 6. Permission Minimization + +The extension MUST request only permissions required by implemented features. + +Expected initial permission set: + +```text +storage +``` + +Expected host permission: + +```text +http://localhost/* +http://127.0.0.1/* +``` + +Firefox match patterns do not support port numbers (Firefox bug 1362809 / 1468162). Therefore the patterns above match any port on localhost. The application MUST restrict the actual connection target to `http://localhost:` or `http://127.0.0.1:` via its own host validation before any Ollama request. + +or the minimum equivalent required by the final Ollama-host design. + +Page access MAY require content-script match patterns for HTTP/HTTPS pages because translation is initiated by selecting page text. + +Do not add broad privileged permissions for convenience. + +Every newly introduced permission MUST be justified in code review. + +--- + +## 7. Trust Boundaries + +The system has three primary trust zones. + +```text +Untrusted Web Page + | + | selected text + v +Content Script + | + | validated extension messages + v +Background + | + | HTTP + v +Ollama +``` + +### 7.1 Web Page + +All page content MUST be considered untrusted. + +This includes: + +- text selected by the user; +- DOM content; +- attributes; +- page-generated text; +- scripts; +- event data; +- iframe content; +- strings that resemble prompts or instructions. + +The presence of text such as: + +```text +Ignore previous instructions... +``` + +MUST NOT cause that text to be treated as an application instruction. + +Selected web content is translation data, not trusted control input. + +### 7.2 Content Script + +The content script is responsible only for tasks that require page access, including: + +- obtaining the user's current text selection; +- positioning the translation action icon; +- rendering the translation popover; +- forwarding translation requests; +- receiving streamed translation text; +- handling local UI interaction. + +It MUST NOT be responsible for privileged network communication with Ollama. + +### 7.3 Background + +The background component owns privileged application operations: + +- Ollama HTTP communication; +- request lifecycle management; +- configuration access where appropriate; +- message validation; +- request cancellation; +- Ollama response parsing. + +--- + +## 8. DOM and XSS Rules + +### 8.1 Plain-Text Rendering + +Page-derived text and LLM-generated text MUST be rendered as plain text. + +Use safe DOM APIs such as: + +```js +element.textContent = value; +``` + +Do NOT use untrusted content with: + +```js +element.innerHTML = value; +element.outerHTML = value; +shadowRoot.innerHTML = value; +document.write(value); +``` + +### 8.2 No HTML Interpretation + +The translation result is plain text. + +Do not implement Markdown rendering, HTML rendering, or rich-text parsing unless explicitly added as a later requirement and separately security-reviewed. + +### 8.3 No Dynamic Code Execution + +The following are prohibited: + +```text +eval() +new Function() +setTimeout(string) +setInterval(string) +``` + +No selected page content, setting, LLM response, or remote response may be executed as JavaScript. + +--- + +## 9. Shadow DOM Policy + +The translation UI SHOULD use Shadow DOM where practical to isolate extension UI styling from page CSS. + +Primary reasons: + +- reduce CSS collisions; +- reduce page-style interference; +- contain translation UI styles; +- improve predictable layout. + +Shadow DOM MUST NOT be treated as an XSS security boundary. + +LLM responses and page text inside a shadow root MUST still use plain-text rendering. + +--- + +## 10. Page Script Isolation + +The extension SHOULD rely on the normal WebExtensions content-script isolation boundary. + +Do not bridge page scripts and extension scripts unless a future requirement makes this unavoidable. + +The following SHOULD NOT be used: + +- `wrappedJSObject` +- `exportFunction` +- `cloneInto` +- custom page-script injection +- page-controlled `window.postMessage` communication + +If page-script communication becomes necessary later, it requires an explicit security design update. + +--- + +## 11. Message Validation + +All messages received by privileged extension components MUST be validated. + +Example translation request shape: + +```js +{ + type: "translate", + requestId: "...", + text: "..." +} +``` + +The receiver MUST validate at least: + +- message is an object; +- known `type`; +- expected fields are present; +- `text` is a string; +- `requestId` is a string; +- text length is within defined limits; +- unsupported fields do not alter privileged behavior. + +Do not dispatch privileged behavior using arbitrary method names supplied by messages. + +Avoid patterns such as: + +```js +handlers[message.method](message); +``` + +unless `message.method` is strictly allow-listed. + +--- + +## 12. Input Limits and Resource Abuse + +Selected text MUST have a maximum allowed size. + +The exact product limit MAY be defined in `Specifications.md`, but an implementation limit MUST exist. + +The purpose is to reduce: + +- accidental huge requests; +- malicious resource consumption; +- unnecessarily long model generation; +- UI hangs; +- memory pressure. + +If input exceeds the allowed limit, the extension MUST fail safely and provide a user-visible error. + +Repeated translation requests MUST cancel obsolete in-flight requests. + +--- + +## 13. LLM Prompt Boundary + +The application MUST maintain a separation between: + +1. application-controlled system instructions; +2. user-configurable system instructions; +3. selected page text. + +The application-controlled prompt MUST state that selected page content is translation material and must not be interpreted as instructions. + +Selected text MUST NOT be concatenated into trusted system instructions. + +Preferred conceptual request structure: + +```text +system: + application-controlled translation rules + + validated user translation preferences + +user: + selected page text +``` + +--- + +## 14. Settings Validation + +Every configurable Ollama generation value MUST be validated before being sent to Ollama. + +Validation MUST include: + +- expected type; +- finite numeric value where applicable; +- supported range; +- integer-only constraints where applicable; +- allowed enum values; +- context-length preset membership; +- string length limits. + +Invalid stored values MUST NOT be passed directly to Ollama. + +The implementation SHOULD fall back to safe defaults or request correction from the user. + +--- + +## 15. Seed Security / Correctness Rule + +Seed configuration MUST distinguish between: + +- variable/random behavior; +- fixed deterministic integer seed. + +When fixed seed mode is enabled, the value MUST be validated as an integer. + +When variable mode is enabled, the implementation MUST use the Ollama/API-supported behavior defined in the specification and MUST NOT generate executable or unsafe random data. + +--- + +## 16. Storage Rules + +Use: + +```text +browser.storage.local +``` + +for extension configuration. + +Do not use page `localStorage` for extension settings. + +The implementation MUST assume `storage.local` is not encrypted. + +Do not store: + +- passwords; +- arbitrary secrets; +- private authentication tokens; + +unless a later requirement explicitly adds such functionality and the security model is revised. + +The initial local-Ollama design SHOULD require no secret credentials. + +--- + +## 17. Content Security Policy + +Keep Firefox's extension CSP as restrictive as practical. + +Do not weaken CSP merely to make a library or framework work. + +Do not enable: + +- remote script execution; +- `unsafe-eval`; +- arbitrary inline executable JavaScript. + +JavaScript SHOULD be stored in local `.js` files where applicable. + +HTML event attributes such as the following SHOULD NOT be used: + +```html + + + + + +
