Rated 5 out of 5 stars
I found the reason for the big slowdown in FF4. It is the usage of the new HW acceleration. Switched this GPU usage off and as fast as before. And not only this add-on. Could be because I do not have a high end graphik card. Happy again with this add-on!This review is for a previous version of the add-on (0.11.2011021901). This user has other reviews of this add-on.
