Loading web pages has become very slow with Firefox (0.8 Mb/s).

IE and Chrome load pages at about 7 Mb/s at same computer.

I have reinstalled Firefox, but it doen't help.

A possible cause is security software (firewall,anti-virus) 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 and the plugin-container 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 and the updater process.


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

Hi, thanks for advise. However I tried both answers separately, but they didn't work for me

- I made my firewall to ask for permission for Firefox to continue - I started Firefox in Safe mode withour making any selections.

I also checked my firewall log and it seems that Firefox has always been allowed.

Any other ideas?

hello jko63, how are you measuring the connection speed - with a flash based test like then it is possibly an issue with the latest flash update & adobe's introduction of the protected mode - try disabling the protected mode or downgrade to a prior flash version to see if this is making a difference...
