I have a problem with my Mozilla Firefox browser for a couple of weeks, whenever I try to start it (clicling double on the icon) it doesn't start, the window is opening suddenly after an hour or two. I tried to uninstall and then reinstall it but it still doesn't work.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, maybe after detecting changes (update) to the Firefox program. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox. See Configure firewalls so that Firefox can access the Internet and http://kb.mozillazine.org/Firewalls
