  • Version 1.5.2

    Released Jul 26, 2026 - 279.83 KB
    Works with firefox 142.0 and later
    • Fix: pasting a URL into a tab no longer leaves duplicates highlighted forever (loading updates were cancelling the flash timer).
    • Removed host access (too aggressive); hover restored in 1.5.1 without host_permissions.

  • Version 1.4.1

    Released Jul 26, 2026 - 279.72 KB
    Works with firefox 142.0 and later
    • Duplicate detection also covers browser system pages (about:addons, settings, …). Empty new tabs (about:blank / about:newtab / …) are ignored. Link hover still works only on http(s) pages.
    • Dropped <all_urls>: no more optional “local files” / over-broad host access. Content script runs on http(s) pages only.

  • Version 1.3

    Released Jul 26, 2026 - 279.39 KB
    Works with firefox 142.0 and later
    • Badge shows how many other tabs have the same page (empty when there’s only one).
    • Opening / switching to a tab with a copy briefly lights up the duplicates, then clears — so closing one tab doesn’t close them all.
    • Defaults: hover delay 10 ms, duplicate highlight 200 ms.
    • Settings: turn counter, tab-open highlight, and link-hover highlight on or off separately.
    • Duplicate matching works while a page is still loading or a tab is unloaded (pendingUrl / discarded tabs).
    • On link hover, the badge shows how many open tabs match that link (not only the current page).
    • Current-page badge only after switching tabs: at least 2 seconds (or longer if highlight duration is higher); idle and after leaving a link → empty.
    • Badge updates sooner (before highlight work; almost no debounce on tab events).
    • Options text rewritten and translated for 19 locales.
