I have completely uninstalled it (lossing bookmarks, codes and all the stuff) and reinstall it again but the same problem occured. When I try to update via the Help menu it shows the error message that installation has not completed properly and the update file XML (200) is corrupted. When I try to update manually nothing changes. Please note that I use the Greek version. Does anyone have any ideas to help me?

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly 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 Server Not Found - Troubleshoot connection problems and Configure firewalls so that Firefox can access the Internet and http://kb.mozillazine.org/Firewalls
