I am having serious performance issues. FF just spins and spins, and rarely gets anywhere anymore.

I have disabled addons, uninstalled/reinstalled, all to no avail. Other browsers work fine for me. I'm at the point where I'm ready to give up on FF and just go to Chrome fulltime, if I can't get an answer to this issue.

I do use quite a few tabs, but I haven't had an issue with that in the past. This issue started a couple months ago, so I went through the various releases, and am now at 7.01 in W7 64, still the same issues as when it started in FF4.

I do NOT have this problem in XP using the same browser version on another machine.

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.
