Works well! very pleased!!!! I like how you can click on the icon to go to the last window in addition to using a personalized keyboard shortcut.

it works perfectly, BUT has an extremely annoying issue where it doesn't remembers a custom shortcut like alt+a and resets it on every relaunch!! 😡

so as a better open source alternative i've gone back to: https://github.com/jscher2000/switch-to-previous-active-tab

FF 109.0.1 - This extension has worked for many years but today it has stopped working. Clicking the toolbar button (the way I like using it) to quickly switch between 2 tabs now does nothing.

Probably the best extension i have on firefox at the moment (as well as most underrated). Its a shame these extensions don't have more users as i think its one of the biggest time savers when it comes to over all user experience of the browser. Its simple, and it does what its supposed to. Seriously, amazing extension and its a shame it has only 340 users. Well done...

Super

I had problems with shortcut until I've found out the reason (Multi-Account Containers extension captured shortcuts, even though set to 'none'). The solution is here: https://github.com/mozilla/multi-account-containers/issues/1814 (go to about:addons, click on the gear in the top-right corner, click "Manage Extension Shortcuts", delete wrong shortcut assigment). Maybe you would like to add this hint to your option page?

Thanks for your extension, please fix error: can't switch tab after closing a tab.
Extension "Tab flip for Tree Style Tab" of "Mélanie Chauvel (ariasuni)" (https://addons.mozilla.org/en-US/firefox/addon/tab-flip-for-tree-style-tab/) works fine, but that extension does not support customize hotkey.

Simple, and just works!

This is fantastic! You should update the FF Add-Ons page; it still says "it's not currently possible to customize keyboard shortcuts" but v.2 of this Add-on does allow it. In reply to M., the "Ctrl+Tab cycles through tabs in recently used order" behavior would drive me crazy. This is completely different, and [Shift-]Ctrl-Tab still works as expected--in the visible order. Finally, a replacement for the old-style FLST add-on that was never updated to work with WebExtensions!

One day it simply stopped working.

Awesome plugin, just what I needed except Firefox doesn't allow overriding of existing keyboard shortcuts. Because Firefox doesn't allow it, it renders the plugin pretty useless if I have to program it to some complicated shortcut that isn't used. I'm still going to be on Chrome and using with the "Alt + Q Switch Tabs Keyboard Shortcut" extension until Firefox fixes this. Switching to last tabs is essential for my browsing, so I won't be using Firefox until then. Great work to the developer of this plugin though.

Is this add-on still needed? At least on FF61 this is integrated under "Options / Tabs / Ctrl+Tab cycles through tabs in recently used order" checkbox and works fine. However the ability to trigger it via click on active tab would be useful (as it was in Tab Mix Plus), but I see it is not currently possible...

I note the problem with making this a single click on the tab to swap, but just wanted to add another request to show this is much wanted when it can be included.

Perfect!

Fantastic addition, even essential. So all that remains is looking forward for Firefox to finally implement proper shortcut management, a limitation I don't understand as many other browsers are providing it for years. And even though I am, thank God, not missing an arm or a hand, CTRL+SHFT+1 is unfortunately near unusable on a German keyboard. Not your fault, of course, and at least I have a button for now. Thanks.

Control-shift-1 is hard to use, can I use Alt-Q for the hot key?
