If the problem does not appear Windows safe mode, then you can be sure that another application (security software most likely) is at the origin of the problem. Then see if you have the same problem in Firefox.
The best way to test it is probably for a boot Windows safe with networking. I have not heard of 25 FF origin of this particular problem, but I've heard other programs such as ZoneAlarm and QTranslate causing the problem on specific versions of Firefox.įor example these two previous requests for support: here and here. CTRL + c does not work in 25 FF in normal mode or in safe mode.
