Tree Style Tab Version History

117 versions

Be careful with old versions!

These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.

Version 2.4.3 683.2 KiB Works with Firefox 57.0 and later

2.4.3 (2017.12.12):
  • Never group single orphan tab (regression on 2.4.2)
2.4.2 (2017.12.12):
  • Keep group tabs open after restart of Firefox and reload/update of TST itself. (regression: group tabs were unexpectedly lost on such cases, at 2.4.x.)
  • Add ability to group new tabs opened from pinned tabs automatically.

Version 2.4.1 677.1 KiB Works with Firefox 57.0 and later

2.4.1 (2017.12.11):
  • Fix regressions around SVG icons and throbber's animation on the simulation mode.

Version 2.4.0 676.3 KiB Works with Firefox 57.0 and later

2.4.0 (2017.12.9):
  • Optimize tree restoration with cache. If you see broken tree from cache, please deactivate this feature by the checkbox under "Debug mode" in Tree Style Tab's configurations.
  • Use SVG icons for closeboxes, "New Tab" button, and sound playing indicator. However, due to the Bug 1377302 and 1421329, it is just a simulation and requires more CPU. If you want to reduce CPU usage, you need to activate svg.context-properties.content.enabled via about:config and deactivate the simulation by the checkbox under "Debug mode" in Tree Style Tab's configurations.
  • Use system color instead Photon color scheme on Linux by default, on Plain, Flat, Vertigo, and Mixed theme.
  • Add new theme "Hight Contrast" based on system color on any platform. (contributed by actionless, thanks!)
  • Remove "Flat" theme. It was quite similar to "Plain".
  • On "Plain" and similar themes, show top border of the tab bar only when there is any pinned tab.
  • Keep tab's "unread" state after reloading of the sidebar.
  • Reduce needless requests for tab icons. (contributed by UENO Katsuhiro, thanks!)
  • Apply extra margin for overlay-scrollbar on macOS only for overflow tab bar.
  • Title editor and checkbox to toggle "temporary" status are avialable on group tabs.
  • Group tab won't be closed automatically if it is not marked as "temporary".
  • Don't detach tab from window if it is dropped onto the bookmarks toolbar.
  • Don't output log for keyboard events.

  • Open new sibling tab at correct position for root level tab.

  • Allow to bookmark all tabs from the fake context menu. (regression)
  • Cleanup tab element for closed tabs correctly. (regression)
  • Calculate size of elements more correctly. (regression)
  • Animation of throbber is now synchronized correctly on Firefox 57. (Many thanks to Lej77!)

  • Hide container selector on the new tab button by default.
  • Add "No Decoration" theme as the base for customization.
  • Use white icon for the toolbar button on the "Dark" theme.

  • Handle middle-click on the new tab button correctly even if any other addon listens click events on the tab bar.
