When I restart Firefox it crashes immediately. The Crash Reporter gives me the choice of Restarting our Quitting. If I choose the Quit option, Firefox resumes starting but I keep getting Crash Reporter. If I persevere, after about 10 times Firefox starts and is usable. But if I quit FF then when I restart the problem occurs again (and again) The error started after a power cut. When I restarted my Apple, this behavior started immediately. Crash ID: bp-82bd1c0b-7088-4c36-bfb6-0bc3c1170424 I have tried (a) starting in safe mode; (b) doing a clean install; (c) restoring by TimeMachine my ~/Librrary/Application Support/Firefox folder to before the problem; and (d) creating a new user, but problem still reoccurs I used Disk Utility to check my disk -- no problems detected and nothing else seems to be misbehaving. Many thanks for any help
