I have tried everything in listed in the troubleshooting guide and also cleared all my history/cache/cookies (everything) and uninstalled and re-installed. Firefox still loads about half of all web pages extremely slowly. IE has been lightning fast at all times that I've had slowness with Firefox. What else can I do besides just using a different browser?

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.

Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.

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 and the updater process.
