Can it run flashgot?
If so that may be reason enough for me to switch away from vanilla ff.
I used to go in for all that SSE/2/3/S3 AVE recompilation stuff, but it honestly doesn’t seem to make much of a difference in Firefox.
I sorely miss being able to prune out all the crap to get to the specific video I wanted to download. Flashgot made tearing through DRM so easy.
