  • Latest version

    Version 1.3.0

    Released Sep 1, 2026 - 17.34 KB
    Works with firefox 115.0 and later, android 120.0 and later
    • This version attempts to fix a bug in tab closing behavior on Android,
      which resulted in runaway closing of inactive tabs if the number of tabs was above limit and
      an inactive tab was activated.


    We have to take some pains to make sure that when an unloaded or inactive tab is activated,
    it doesn't count as a new tab load and get closed automatically. We implement a cooldown
    period on new tab closures controlled by CLOSE_QUIET_MS (default 500 ms)
    such that a new tab opening less than a 500 ms after the last tab closed
    or a new tab opening with a URL already loaded and no openerTabID is considered a legacy tab and not closed.
    We also implement a circuit breaker,
    where 3 forced closures in 10 seconds will cause the addon to stop enforcing the tab limit until FF is restarted.
    This should limit the damage if we have a bug which closes tabs that were not actually new.



    FF on Android only provides a count of currently loaded tabs to extensions.
    This means that inactive tabs and tabs that are unloaded (not in RAM) will not appear in the tab count.

    Version 1.2.0

    Released Aug 30, 2026 - 16.33 KB
    Works with firefox 115.0 and later, android 120.0 and later
    • Disable the tab ceiling by stepping the counter limit past 30 tabs.
      In "Always" mode links are still collapsed into the current tab
      regardless of the counter setting.
    • "Load links in the current tab" replaces the old on/off setting with three
      modes, defaulting to Never:
    • Never: at the ceiling, a new tab is closed and its URL dropped. This
      preserves the state of the page you are currently reading.
    • At ceiling: at the ceiling, the URL loads in the tab you tapped the
      link from instead of being dropped. Under the ceiling, links open new tabs
      normally.
    • Always: links never open new tabs.
    • target="_blank" links are now only rewritten into the current tab in
      "Always" mode. Previously they were rewritten at every tab count regardless
      of the setting.
    • Settings from earlier versions are migrated on first run.
      This affects exactly one user.
    • Rewrote the add-on description.
    • Removed tab counting dependence on windowId. Firefox for Android has no
      window concept. Tabs are now matched on their private-browsing flag.
    • The popup now shows an error in place of the tab count when it can't read
      tabs, rather than sitting on placeholder dashes.
    • build.sh creates build/ if it's missing, and replaces the archive instead
      of appending to it. Deleted files could previously survive in later builds.
