Hermes Browser Extension v0.3.0

This is the largest Hermes Browser Extension update so far, with major improvements to browser context, local-document workflows, session reliability, privacy, customization, and the overall Firefox experience.

WHAT'S NEW

• Added approved local HTML, browser-rendered PDF, and localhost workflows. Local files require both Firefox file access and explicit Hermes Browser approval.

• Added configurable right-click actions with current-session, new-session, and background routing.

• Expanded localization across 21 languages and added complete browser-native locale packs.

• Improved Hermes Assist reliability, model routing, session creation, launcher placement, safe draft application, and duplicate-injection protection.

• Added stronger Cloud session continuity, dashboard profile discovery, asynchronous delegation recovery, and session-scoped model/provider selection.

• Added cross-surface text zoom, accessibility-focused font profiles, validated custom themes, VS Code theme imports, and Agent Theme Studio.

• Improved the Side Panel settings experience with a persistent header Save action, compact close control, clearer button alignment, and simplified settings organization.

• Fixed Issue #73 by opening the /commands and skill menus above the composer, keeping long prompts visible without covering or compressing the text area.

• Improved startup diagnostics, control-state presentation, attachment controls, keyboard behavior, reduced-motion support, and responsive layouts.

• Added stable Firefox add-on identity and Mozilla-hosted automatic update support.

SECURITY AND PRIVACY

• Sensitive fields, credentials, payment information, MFA values, restricted browser pages, stale document references, and credential-bearing URLs fail closed.

• Browser context remains explicitly user-controlled and bounded.

• Local-document access does not bypass sensitive-action or restricted-page protections.

• Controller and companion diagnostics retain bounded metadata and redacted receipts only. They do not persist raw page text, typed values, credentials, screenshots, response bodies, PDFs, or uploaded file contents.

• Hermes Browser does not request cookies, browsing history, bookmarks, password-manager access, or native messaging.

FIREFOX COMPATIBILITY

This release supports Firefox 142 and newer.

Firefox receives the capability-safe WebExtension feature set. Chromium-only debugger access and trusted-input browser control are not enabled or claimed on Firefox.
