pw> That's sort of the point of safe mode, isn't it? You can pw> uninstall extensions while in safe mode, and then try to start firefox. Now I get it! I did look at the "extensions" window while in "safe mode", but didn't realize each entry was, in fact, usable since everything was grayed out. So, I'll now remove "likely candidates", and restart 'firefox'. Thanks for your and others' help! -Kenneth
