Rated 5 out of 5 stars

I love it!!! I have been waiting for an extension like this for a long time. Find In Tabs is lean (not bloated like many extensions seem to be), and effective (working flawlessly so far.) It has a simple & versatile interface, too. One feature suggestion would be to have a keyboard shortcut for the "Find in Tabs" button - or at least be able to tab over to the button (from the find input field) and press "space" or "enter" to search in all tabs. By the way, I have 40+ extensions installed and so far Find In Tabs has not conflicted with any of them. :-) Works fine with XUL/Migemo [another extension for the find bar], which automatically keeps "highlight all" selected for normal find bar searches (not in all tabs). Find In Tabs is very useful to me - it is small, yet does exactly what I need - and does it well. I'm very pleased with this add-on. :-)

This review is for a previous version of the add-on (0.1). 

Keyboard Shortcuts

To activate find in tabs with the keyboard you can:
ctrl+f to activate find.
alt+t to activate find in tabs.

Unfortunately I do not believe it will be possible to have a dedicated keyboard-shortcut for FiT without going through the findbar.

Thanks for your pleasant review. I'm glad you like it.
