After updating Firefox on my old XP Lenovo, I found it unusable,as it consistently froze on opening. I removed it and made do with IE for the last business trip, but coming back to the office I find that not only does Firefox (8.0) freeze when shutting down on the W7 desktop, but both Firefox and IE will freeze on opening (blank page). I suspect it is either a Google Toolbox issue or the Firefox update, but wonder if anyone else has insights. No errors, nada.
