User Help for Mozilla Firefox
Please note, this is an informational thread, not a support thread. If this does not work for you please start a new thread. Thanks.
A few people who suffer from Firefox not loading pages entirely and from high CPU usage have found the fix below works from them.
1) In the address bar, type about:config
2) If it shows up, click on I'll be careful
3) Filter for network.http.max-connections.
4) Change this from 256 to 48.
5) Restart Firefox.
Thanks to the guest who originally posted this.

James, that page is out of date. It has a date of 2008 on it, and does not even mention the new value of 256.
^ I just updated that page.
A mind is a terrible thing to waste. Mine has wandered off and I'm out looking for it.
These steps did not work for me. I already had mine set at 256.
Also, I have uninstalled / reinstalled. Cleared cache. Disabled all plugins. Performed a virus scan and a malware scan. IE8 is working correctly on my computer. I have installed all flash updates. When freezing, the process will peg one of my processors at 100%, then that 100% bounces around from processor to processor. I have an AMD Phenom II X6.
it worked for me, thank you. firefox almost lost me as a user as i was starting to use chrome. the last 2 updates for firefox have had this issue.
Hmm ... until yesterday I was getting this problem on just one vBulletin site. It went away this morning. I then saw this thread so checked in about:config, to find that it was "user set" at 40. Possibly a fix just bumped through, but only on beta 8?
Since the page that describe the setting doesn't go into it...
I don't seem to have a problem with the 256 setting. If I lower mine to 48 (or 40), would that have a negative performance impact in my case? My guess is that lowering the value might cause a page to load slower due to http requests being queued. I just ran a netstat and noticed 50 http connections.
Just wondered. Thanks.

Wow this worked for me. I mean it's only been about 15 minutes, but I seem to be back in business. I tried all the other fixes and had even moved to the 64bit beta. I finally posted on an old thread here and the moderator pointed me towards this. I guess I can stop using IE, chrome, and opera.
Oh and it’s plenty fast, so don’t worry about that.

LoudNoise, if anyone can verify this as a reproducible problem, should it not be reported as a bug?
