Today my windows update. After that firefox stop working. Don't wanna start in safe mode too, always crash report show. Download new version but still don't work... delete all profile, clear registry (use jv16 anc ccleaner)... but still the same problem, don't start and always send raport. From one of ur topic i copy my profile from folder to another (before coplete delete firefox). Soo full new profile create and don't work... use Chrome to copy my profile site + password (before copy old profile to firefox folder) and now don't have option in chrome to copy again from firefox :/
