BAD lag while moving around the bookmarks with this - whereas the unity bar bookmarks doesn't have any lag at all.
To me that is unuseable - it is far too annoying to use this add-on on that sole reason. Happens with latest firefox official and beta as well as with 12.04 ubuntu fully updated as well as pre-release updates and 12.10 ubuntu beta fully updated. So it always lags.
Firefox is already a mess on linux and this only makes it feel that much worse.
I recommend not installing it unless it is or even can be fixed.
Its better to try to make firefox feel more responsive with its performance problems already then it is to make it worse and this makes it worse.
