No, that did not work because the issue its not related with that, Its the engine or something.

When this happens Firefox is using 27% of my cpu even with a blank tab also another user said me that It was using the 100% of the cpu.

No... that did not work, Im telling you is related with the engine.

I found a fix but I want to know about this.

in about:config search this.

network.http.max-connections

network.http.max-connections-per-server

network.websocket.max-connections

Their values are: 256 , 15, 200 And I changed for this 10, 1, 10

And then the pages with a lot of images load fine.

But these numbers are a little random, with 1,1,1 works fine too. So I want know how changing that can affect other things for Firefox and maybe the developers can say whats going on with this issue.

I have the same values of these preferences which you have now changed i.e. they are 256, 15, 200 and i don't have any problems with my Firefox.

I don't know anything about these preferences though.

Thanks for the ideas (cor-el and mha007), but I have the same issue and i'm pretty sure it is not my firewall (Comodo), is not my antivirus (NOD 32), is not a malware. I tried cleaning everything, reinstalling everything, and nothing seems to work. I have no add-ons, so neither is their fault.

I post this to confirm that usual solutions doesn't work on this issue... I even posted a new thread (before finding this one), but instead of images, I guess it's because of Flash content... i'm starting to think maybe Jobs wasn't wrong about Flash...

I can not play online games, eg: y8 , friv , kizi

Check and tell if its working.

The problem its not related to flash, I can confirm that.

FrancoFA try my fix:

Like I said I dont like change this parameters until a Firefox worker tell me whats going on with this.

Firefox developers any help with this?

Probably only changing network.http.max-connections to its old value of 30 is sufficient. The increase in Firefox 7 to 256 may be too much.

I installed FF7 a couple of days ago, and it did nothing but hang. Closed it and it stayed open somewhere requiring a reboot. Gave up and put 3.6 back. Works fine.

FF support leaves much to be desired, which if you are reading this, you know.

I solved my FF problem thanks to cor-el's suggestion. I changed network.http.max-connections to 25, and network.http.max-connections-per-server to 8. FF 7.0 has worked flawlessly for about 3 weeks now. It used to hang several times a day.

Thanks.

I did what "cor-el" suggested but after I change the value and restart firefox it again freezes, on looking back at the values they somehow reset themselves to

network.http.max-connections;96

network.http.max-connections-per-server;96

network.http.max-persistent-connections-per-proxy;16

network.http.max-persistent-connections-per-server;16

network.http.pipelining;true

network.http.pipelining.maxrequests;8

network.http.pipelining.ssl;true

network.http.proxy.pipelining;true

I changed again, but after I restart it again goes back to the above and the firefox still freezes.

I also went and did a google image search of "firefox" and browsed till 6-7 pages and it loaded all the images but it did not freeze but when I went to google.com and clicked on news it froze after loading text part of the news and some images, so I do not know if it happens due to too many images being loaded or connections or whatever.

Still stuck. I have upgraded to firefox 7.01 I have added the screenshot. (You need to clear the cache otherwise firefox picks up from the cache and you cannot replicate)

Make sure that you do not have a file user.js to initialize prefs on each start of Firefox or have other problems with the file prefs.js.
