Recently I was writing about my problems with Firefox. Annoying but I could live with it.
But after upgrading to version 3.5.1. my Firefox has died on me. Permanently. I tried everything reasonable to fix it, tried to start firefox in safe mod, rebooted computer. Did little of googling. It didn't help... This error keeps popping up again and again:

The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll.
So long Firefox it was good while it lasted.
