Question

Firefox 5 won't access the internet. I had to uninstall and reinstall an earlier version. Now I'm annoyed by "update firefox" messages.

Answer 1

Do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.<br /><br />

You can also do a check for a rootkit infection with TDSSKiller.

Also make sure that the firewall isn't blocking Firefox if you've used system restore.
Note that using System Restore can cause your Firefox installation to get corrupted because not all files are restored (only files in a white-list), so be cautious with using System Restore.<br />
You may need to (re)install software that was affected.<br />
Delete the Firefox program folder before reinstalling to be sure that all files get updated.
