Love it! Rated 5 out of 5 stars

I just spent an hour trying to figure out why clicking on my tabs didn't instantly switch to the selected tab. Finally, after disabling FindBar Tweak things went back to normal. This is definitely a 5 star extension functionality/feature wise. But, the hit to performance just isn't worth it.

Dev contacted me directly and has worked successfully to improve the performance of Findbar Tweak. Tab switching with or without the FT is equally quick now.

This review is for a previous version of the add-on (1.2.0). 

Update: I'm glad the issue is now resolved. Thanks for updating the review!

Maybe you should consider this a bug, rather than just dismissing it as faulty by nature...

This is the first I'm hearing about such a slow-down when switching tabs (I'm assuming this is what you mean as you weren't very explicit either). Any extra information, such as what firefox version, operating system, any errors reported in the error console (Ctrl+Shift+J) when switching tabs and, most importantly, if the same happens when FBT is the only add-on enabled, would be greatly appreciated.
