Rated 4 out of 5 stars
This needs a new version, cause I had to uninstall it because of too many script errors, which meant it was crashing. My Firefox seems a lot faster without it so far, but now my toolbar looks ugly. Using 24 Beta 10.This review is for a previous version of the add-on (18.104.22.168-signed).
No script errors here. Works fine for me on every nightly, aurora, beta and final up to Fx 26 (incl. UX).
Where do you see the errors, in the error console?
Already tested on a clean empty profile?
