XPath Highlighter de mrkptt

XPath Highlighter is a tiny, fast tool for testing XPath directly on any webpage.

Features
• Instant highlighting while you type.
• Results list with readable labels (TAG#id.class — "text").
• Click a result to scroll to the element and briefly “flash” it.
• Works with element, attribute, and text-node matches.
• Remembers your last XPath between popup openings (local only).
• One-click Clear button to remove highlights.
• RU/EN interface (auto based on browser language).

How to use
1. Click the toolbar button.
2. Type or paste an XPath (e.g., //a[contains(@href,'login')]).
3. Review matches in the list; click any item to jump to it.

Permissions explained
• activeTab — run only on the tab you click the extension on.
• scripting — inject minimal CSS/JS to draw highlights and list matches.
• storage — save your last XPath and UI language state on your device.

Privacy
• No data collection. No network requests. Everything runs locally in your browser.

Limitations
• Not available on Firefox internal pages (e.g., about:*) or AMO pages due to browser restrictions.
• Cross-origin iframes and Shadow DOM may limit what XPath can access.

Compatibility
• Firefox 109+ (Manifest V3).
