Even after years of instability and slowness, I stuck with it. Then, finally, they did a major upgrade that seemed to fix the problems. Of course the one extension - Session Manager - that was the main reason I used Firefox, no longer worked. Yet still I stayed, and every time it said to update, I did. Now it's worse than it ever was. It is excruciatingly slow, and completely unstable, and I have had it. I hate Chrome, but it works, and, if I have to use some second-rate session manager, it may as well be under Chrome.

Just ... fed ... up!
