Great, but remains broken Rated 5 out of 5 stars

To be clear, I'm giving this five stars for the functionality it had in the past. Being a both a tab messie and "keyboard centric", I found this add-on incredibly helpful. Unfortunately, from FF 42 onwards, it longer works, as described by Seaonos below. That's why I was overjoyed when I found this in the available updates, but no such luck – it was an old update from 2014 that for some reason didn't happen earlier (weird).

Here's hoping that the developer (Tabby2 is a new version of the earlier Tabby that also stopped working at some point) will re-discover this, or that someone else with the necessary know-how will take care of it.

Perfect for mouseless browsing Rated 5 out of 5 stars

Together with VimFx, this is just perfect for using Firefox mouslessly (if Vimperator is overkill for you). The only thing I would change: Although the tab list is numbered, it's not possible to type those numbers to go straight to a tab. It would be nice to just type a number instead of a part of the tab title.

Update 2016-03-11: Unfortunately, Tabby2 no longer works in FF 45. No response to keyboard shortcut; in options, the field for the keyboard shortcut is empty and it's not possible to enter anything. When clicking on the icon opens the search bar, but it doesn't respond to any queries typed into it. Still 5 stars for the time being, hopefully this can/will be fixed.

Thanks so much! Rated 5 out of 5 stars

Thanks for updating and improving this! An essential add-on for everyone who must keep many tabs open at a time. One reason less to stick to 3.6.xxx. :)

This review is for a previous version of the add-on (0.31.1-signed.1-signed).
