Thank, maybe it is not good for someone, but for me, it is very usefult, sure!It very very suite with my addon pack, with it my Firefox seems like don't leak RAM anymore, it is very fast at all. Switch both private and public browsing is excited.Sorry, my bad English : (When Firefox > 200MB RAM, I switch to private browsing, switch to public browsing and problem fixed!

Now I need an addon that can quickly switch to Safe Mode(no addon, no history), can you make it ? Thank!
