Rated 5 out of 5 stars

Is this due to the mentioned developer changes from the release notes? And/or is this the beginning of the end for the new API? Help us Quicksaver, you're our only hope... :-P

'Highlight All' by default won't work on one of my PCs.
I tried resetting with defaults, disabling, and removing the Extension; 'Highlight All' still wouldn't default on. I can manually enable it on the Findbar, so then I checked about:config and found "findbar.highlightAll" set to false; enabling it fixed the issue. So FindBar Tweak is no longer able to set that parameter; perhaps a Firefox or Extension change?

<Update:> beta has fixed the (continued) issues; for those looking for it... https://github.com/Quicksaver/FindBar-Tweak/releases

This review is for a previous version of the add-on (2.1.10). 

Yep, I'll release a final update soon. Thank you for updating the review to mention this. :)
