Every new update seems to bring slow or lagging performance to Firefox. How can I get better performance?

Just updated to 7.0 and now to 7.01 and have performance issues on my fire breathing Win 7 64 system. I am constantly getting the refresh blue circle and screen dimming...this will go on for a couple of minutes and I have to go to the Task Manger to end process to get out of firefox.

I had the same issue on my Win 7 64 bit system. The browser became incredibly slow. I found these performance tweaks which have made and amazing difference in 7.01. http://techfragments.com/news/538/Software/The_12_Best_Firefox_AboutConfig_Performance_Tweaks.html

I did not make the ram tweak and the tweak for content.notify.backoffcount actually made things worse. Other tweaks I did not do are the browser blink, mouse to paste, and source editor since these really don't seem performance related.

OMG - this update has completely stalled my connection! Even images are not opening completely????

It kept prompting me to update and finally I gave in - im about to restore my OS to earlier date - this is crazy slow now?

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 255 to a setting like 30 as used in Firefox 3 versions.
