Very handy indeed. Just one point to bring attention to : if after an update of TST the module works no more, before uninstalling and reinstalling, be sure not to forget the name, or you will have difficulties to find it again.

Thanks for your extension, please support customize hotkey.
Extension "Most Recent Tab" of "Paul V" (https://addons.mozilla.org/en-US/firefox/addon/most-recent-tab/) allow set keyboard shortcut (I often set Alt+...), but that extension has an error: can't switch tab after closing a tab.

Very good. Works perfectly. Thank you!

His feature I missed since years. Great!

Update: Thanks for the swift update now works perfectly!

Edited review:
The below issue has been corrected in a few hours - thanks a lot! :)
In all its glory, again! :)

Original review:
It would be kind of an Alt-Tab for tabs.
Unfortunately, the functionality has been broken for several weeks: if I click on the current tab, it should switch to the previous one, but it no longer does it - the previous tab's button is flashed for a microsecond, but then the focus gets back to the current tab. The keyboard shortcut works well (which has been changed to CTRL+F2).
I've just realized it is a known issue, without fix for a while: https://github.com/piroor/treestyletab/issues/2127

Sorry I don't have a Framagit account so I report an issue here.

Tab flipping by mouse clicking is broken since TST 2.7.8, probably by this changelog "Allow to cancel default behavior of clicking on twisty, sound button, and closebox on tabs via API."
Tab flipping by Ctrl+F2 still works.

Thank you for such a useful extension!

Work with hotkey trigger, does not work with click current tab.

Doesn't work on https://www.mixcloud.com when online music playing, Space press was capture by website as pause, even if I did press Ctrl+Shift+Space.

Windows 10 1803, Firefox Developer Edition 62.0b12 (64bit), Tree Style Tab installed.

Edit: LOL, thanks for the dev's quick response, though when it was updated to Ctrl+F1 I found it too hard to reach, now it's a lot better!

P.S.: It would be perfect if it can be configured to use a customized shortcut.
(like this: https://github.com/ueokande/vim-vixen )
(or like this: https://github.com/victal/quickcommands )

P.S.S.: I found that maybe Mozilla should have a unified interface to let user able to manage hotkeys of various extensions, just like Github Atom did.

Unobtrusive, does what it's supposed to do.

I spent 15 minute to understand what the extension was really doing. Actually, it goes to the last active tab when clicking again on the active selected tab. This work as expected.
For the moment I don't know what this can be used for... Could you please give some use cases in the description?

Edit: you're right, the ability to switch between two tabs that are not close is actually very useful! Nice idea!

Seems to work. Thanks!

Adds extra functionality to Tree Style Tab without any drawbacks that I can find. The keyboard shortcut is also quite useful, makes it easier to multitask in some cases.
