Just upgraded to firefox 4 and websites are now taking ages to load, there were no problems when I downloaded the upgrade. Is there a fault with the new version of firefox?

Did you check your security software (firewall)?

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, 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 and the plugin-container process.

Hello, Thanks for the suggestion, I checked the firewall settings, I removed firefox and then added it again manually but it is still taking much longer than it used to, to load websites. Any other suggestions?

You're welcome


Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).


In Firefox 4 you can use one of these to start in Safe mode:

  • Help > Restart with Add-ons Disabled
  • Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
