Since the last update to FF 31 (Ubuntu 14.04 64 bit), the ENTER key has stoped working -> when typing web adress in URL bar. Hitting ENter does nothing, as well as the GO arrow (nothing as well). All other applications are fine, only FF is not registering the input. I did not install new addons, so plese don't tell me to reset. It was fine yesterday, is wrong today after update. Don't blame addons for something that is not related to this. Thanks.
