So happy to find this add-on, works perfectly! This really should be added to Firefox itself, so useful.

Exactly what I needed. Firefox should include this functionality by default, and should allow you to select what hotkeys to use (ALT+Q is perfect)

There currently appears to be an odd behavior though. If you have multiple browser windows open and you are navigating between tabs between browser windows it will not remember your previous tabs.

For instance. I have 2 windows open, each with 2 tabs in them. I click on the 2 tabs in one browser window, and I can Alt+Q between them no problem, but then I go to another browser window, click on a tab, and come back to the original window, the original window doesn't remember the previous tab anymore.

Note that you can get the same effect without an add-on by setting browser.ctrlTab.sortByRecentlyUsed ! Google that.

I've been looking for a super simple way to just use the keyboard to switch to my previous tab without any extra bloat and this extension does the trick perfectly. Thanks!

I was really interested in how you were able to code this up, I imagine it is fairly simple, and I know some programming, so I was curious if you would be interested in sharing the source code or something. I would appreciate that a lot.

This litle feature i miss very much (imo should be in base). TabToggle is decent substitution old FSLT addon.
