This is the parity release: the Firefox build now matches Chrome and Edge feature for feature.

New: Copy All Colors on Page, area readout and Shift snapping in the measure tool, a full saved fonts history with live previews, right click text color picking while eyedropping, a welcome page on first install, a toolbar badge that shows when a tool is armed, and a Firefox themed starter palette.

Also new in this version: the manifest declares data_collection_permissions "none", Mozilla's machine readable way of saying this add-on collects and transmits no data.

Fixed: a long list of small issues found in a full audit, including more accurate color sampling on images and video, better badge behavior across tabs, and dark mode contrast repairs. Full changelog: https://github.com/LXBStudioLLC/web-design-ruler/blob/main/CHANGELOG.md

What's new in v2.0.1

• Popup tool buttons now work reliably. Clicking Color Picker, Font Detector,
or Measurement Tool in the toolbar popup activates the tool every time —
no more silent closes or unresponsive clicks.

• Faster and more responsive overall. Rewritten on top of native Firefox
WebExtension APIs (browser.* with Promises) instead of the previous
Chrome-shim, so message passing and tool activation feel quicker.

• Smarter clipboard handling. Colors, font details, and measurements copy
cleanly via the modern Clipboard API, with a graceful fallback on older
Firefox versions.

• Right-click menus stick around. The "Pick Color / Identify Font / Measure"
context-menu items now reliably reappear after restarting Firefox.

• Clearer error messages. If something can't run (a browser-internal page,
a blocked tab), you get a visible notification instead of nothing.

Same privacy guarantee as always: 100% offline, no data collection, no
trackers, no ads, no remote code. Minimum permissions only.

Security Fix: Removed innerHTML Usage

What was fixed: Replaced all innerHTML assignments with safe DOM manipulation methods using createElement() and appendChild() to prevent XSS vulnerabilities.

Why it matters: Using innerHTML can expose the extension to script injection attacks. The new approach creates DOM elements programmatically, ensuring user input and external data cannot execute as code.

Key changes:
- Created helper functions createElement() and clearElement() for safe DOM manipulation
- All dynamic content now uses textContent instead of innerHTML
- Color swatches, labels, and UI elements are built using proper DOM methods
- No functional changes - the extension works exactly the same, just more securely

This makes the extension compliant with modern security standards and store requirements.
