Using Vista home premium. Connect through a router and a satellite modem. Sometimes this message pops up instantly when I click a tab or link,sometimes after a few seconds.When I hit reload the page will load fine. This happens on all sites I visit regularly.

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.

This has been going on for about a month now. Guess it could be firewall related but when it happens all I have to do is hit "reload" and the page will load fine. If it was firewall related it seems like the pages would not load at all. I get no messages that the firewall has blocked any site.

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.
