Firefox 3 locks up internet connection?

[nantucketbob]

AFter I installed Firefox 3, my internet connection gets locked up somehow.  Clicking on a link gets a timeout message.  Outlook cannot access the internet, either.  Restarting cures the issue.  I have not yet tried using the internet with a different computer on my home system.  Linksys/Cisco wired router.  WinXP pro on all machines.

I haven't really got an answer to whats happened to your PC. All I can tell you is when I downloaded SP3 loads of thing stopped working on my PC, so I uninstalled it, now everything works just fine.

Did you recently install SP3?

When did the problem start?
