My browser has been freezing up quite often as of late, but since I updated to 3.6.10 every time I open up my browser its like I just installed it for the first time. None of my settings or add-ons will stick. If I try to change personas it goes back to default when I close and re-open the browser. Also every time I open up firefox it brings up the website pages for all of my add-ons in different tabs like it does when it updates any of them even though it hasn't made any updates. It won't allow me to set a homepage either. And it also won't save any of the exceptions I allow through No Script. Its like my add-ons all restart like they were just installed for the first time every time I open up my browser. I also notice Yahoo toolbar no longer works.
