Release Notes — v6.1.0

Summary

This release is a major architectural refactor of the content script, addition of a new supported platform, and a fix for the extension icon not displaying in about:addons.



What Changed

Core refactor (content-scripts/main.js)

The previous implementation (~1,000 lines) used per-element MutationObserver tracking and separate code paths for each editor type (ProseMirror, Quill, Tiptap, textarea, generic contenteditable), including direct DOM manipulation and multiple fallback strategies.

This has been replaced with a single keydown listener registered at the document capture phase (~110 lines total). The new logic is:

• Plain Enter on <textarea> — inserts \n directly via the native HTMLTextAreaElement.prototype value setter, then dispatches an input event. This is necessary to trigger React's onChange without bypassing its internal state tracking.
• Plain Enter on contenteditable — re-dispatches the event as Shift+Enter (isTrusted: false) so the host site's own handler inserts the newline natively. No DOM mutation is performed by the extension.
• Ctrl/Cmd+Enter — finds the nearest enabled submit button via CSS selectors and calls .click().
• Shift+Enter — not intercepted; passes through unchanged.

The isTrusted guard on the listener ensures re-dispatched synthetic events are never re-intercepted. No new permissions are required.

New platform: Felo (felo.ai)

Added *://felo.ai/* to content_scripts matches in manifest.json. Updated supportedDomains in background.js and the platform list in popup.js / popup.html. Felo uses a <textarea> input, handled by the direct value insertion path above.

Icon fix (icons/icon.svg)

Removed a <linearGradient> element referenced via fill="url(#shine)". The url(#id) reference fails when SVG is rendered as an image source (as used by about:addons), causing the icon to not display. Replaced with an equivalent fill="#fff" fill-opacity="0.10" on the same <rect>. No visual change to the icon.



No Changes To

• Permissions (activeTab, storage — unchanged)
• background.js logic (icon update + message relay — unchanged)
• popup/ UI and CSP-safe DOM construction (unchanged)
• Manifest version (still MV2)

v5.0.0

New

• Redesigned icon — replaced the previous PNG icons (16/48/128px) with a single scalable SVG. The new icon features an amber rounded-square background with a white ↵ arrow and a subtle keyboard key border outline.

v4.0.0 Release Notes

Removed

• Visual Focus Ring Indicator
  Removed the green focus ring overlay that previously appeared on detected input fields. The indicator caused friction in real-world usage and exhibited unstable positioning on certain platforms.
• Unsupported Platform Manifest Entries
  Removed URL match patterns for devv.ai, felo.ai, and perplexity.ai. These platforms were never officially supported, and the leftover declarations caused unnecessary content script injection.

Version 3.0.0

Popup UI Redesign
- Replaced the generic purple gradient with a clean Warm Light theme using refined typography (DM Sans + JetBrains Mono)
- Keyboard shortcuts are now displayed as styled keycap badges with descriptive labels
- Status indicator changed to a compact dot + animated toggle switch
- All 5 supported platforms now listed with their domain URLs: chatgpt.com, claude.ai, gemini.google.com, chat.mistral.ai, grok.com
- Unsupported-site view also shows the full platform list with URLs

Improved Focus Ring Indicator
- The green focus ring that appears on supported input fields is now rendered as a position: fixed overlay, preventing it from being clipped by parent overflow: hidden containers
- Ring position now correctly follows the visual input box boundary rather than the raw editing surface
- Focus ring appears immediately even when the input is auto-focused on page load
- Smooth fade-in/fade-out transition on focus and blur

Bug Fixes & Code Quality
- Fixed all innerHTML string assignments replaced with safe DOM APIs for Mozilla AMO CSP compliance
- Toggle button state now managed with classList.add/remove instead of full className replacement

Version 2.0.0

What's New

Security & Compliance

• Mozilla CSP Compliance: Replaced all direct innerHTML assignments with safe DOM APIs (createElement, appendChild, textContent) to comply with Firefox extension Content Security Policy requirements
• Updated popup unsupported site message rendering
• Refactored ProseMirror newline insertion methods
• Improved cursor positioning logic for safer DOM manipulation

Platform Support

• Extended extension name to reflect full platform support: Claude.ai, ChatGPT, Google Gemini, Mistral Le Chat, and Grok
• Confirmed compatibility across 5 major AI chat platforms

Bug Fixes & Improvements

• Fixed document-level event interception for Claude.ai's Tiptap editor
• Enhanced event guard ordering in capture-phase listeners
• Improved support for Le Chat's ProseMirror implementation
• Fixed Quill editor handling with multiple fallback approaches
• Added proper stopImmediatePropagation() handling for robust event management

Technical Details

Breaking Changes: None - this is a minor version bump focused on security and stability.

Compatibility:
- Firefox 45+
- No additional permissions required
- No external dependencies

Changes:
- Bumped manifest version from 1.0.0 to 2.0.0
- Refactored DOM manipulation to use native browser APIs instead of HTML string assignments
- Simplified cursor positioning logic for ProseMirror editors

Migration Notes

Users should simply update the extension. All keyboard remapping functionality remains unchanged:
- Enter → Insert newline
- Ctrl+Enter → Send message

No user configuration changes are needed.
