Firefox keeps loading pages forever... or stops loading pages

Hi everyone... the issue I have is pretty much this:

I open a website, or some websites, and one of them keeps loading forever and it makes the other sites also loading forever. So, Firefox stops working as if there was no response from the servers...

If I open a new tab, it goes to the same and loads forever, but never gets to actually load any content at all...

The only way to fix this is by closing the window, and starting all again...

There is no particularly site, sometimes happens with Hotmail, Emol.com (chilean newspaper site), a forum, or just any site...

I have this issue since Firefox 6, but it was a lot less recurrent, I was able to use almost normally... it the problem comes, just restart the browser... the same solution...

Also, I'm pretty sure is NOT a net issue, since I don't have any problem at all with Internet Exlorer, or any other software.

I usually use FF in Private Browsing, but this problem occurs in both normal and private mode.

What I think it could be? I noticed EVERY page that makes the issue come up, has flash content... maybe Flash Player is the guilty, or the Plugin-Container handling it...

Things I have tried:

  • Re-installing the browser as admin
  • Clearing Recent History (Everything)

I guess that's all, any question or suggestion, please post it, I'll be checking this thread as often as I can.

Thanks for your attention, even if you just readed this.


PS: Sorry for my english, I speak spanish...

Re: Firefox keeps loading pages forever... or stops loading pages

@yesyes - Did you perform the suggestions mentioned in the article provided my previous reply ?? IF Yes, then try the following:

Type about:config in the Location (address) bar and press the "Enter" key. When you see a warning, click I'll be careful, I promise! button.

-> In the Filter bar, type network.http.max-connections

  • Right click the preference network.http.max-connections and choose Modify
  • change the value to 30 or 48
  • click OK

Re: Firefox keeps loading pages forever... or stops loading pages

I have this problem as well. There are also other questions here that seem to have the same core problem. Some of my personal troubleshooting process/config settings:

  • I'm running Windows 7 on my desktop and Windows Vista on my laptop. Both have this problem.
  • I'm running Firefox 7, this originated on Firefox 6 (Firefox 5 is fine. I uninstalled 7 and installed 5 to test. No problems on 5.). Has happened to me more often on 7 than it did on 6 as far as I can tell.
  • My internet IS working. IE9, Chrome, third-party download programs, etc. still work just fine as well, WHILE Firefox is stuck on loading sites.
  • Active downloads slow, then eventually stop at "0 kb/s" and stay that way until restart inside the Firefox download manager.
  • The site(s) inside tabs don't seem to matter. Browsing sites without any Flash elements still results in the loading error.
  • Running Firefox in safe-mode doesn't help.
  • Starting a new Profile doesn't help.
  • Uninstalling/re-installing doesn't help.
  • Even a "clean" install (Uninstalled, then removed all instances of Firefox from the registry, deleted all profiles/personal Firefox folders/setting files, etc.) on laptop and it still has this problem.
  • Removing and re-adding Firefox to my firewall's "allowed list", as well as disabling my firewall and virus protection program has no effect.
  • Closing Firefox and re-opening it allows content to load normally... at least until it gets stuck on the loading error again.
  • The error can happen at any time. Sometimes 5 minutes after opening Firefox, sometimes it's fine for hours before the error appears.

That's all I can think of right now. Hopefully someone knows of a fix for this, or hopefully it is being fixed. I'd really hate to leave Firefox after using it for so many years, but if it can't "do the basics" I might have to move over to Chrome or something until this has been ironed out... and I REALLY don't want to do that.

Re: Firefox keeps loading pages forever... or stops loading pages

I have the same problem. I have found a few websites that always cause the problem: - ebay.co.uk (enter a search term and click search -> FF stops loading any pages) - youtube.com (also after doing a search) - Google Images (again, after a search, it loads a few of the image results, the rest remains grey and FF does not load any further pages)

When the issue occurs FF just says "Connecting to ....com" in the status bar whichever page I want to open. It also happens with pages that are already open and I click refresh.

At this point everything still loads fine in IE, so I doubt it is a network issue.

I have tried deleting temp files as mentioned in an earlier reply here but this has made no difference.

I'm currently running FF 7.0.1 but it also happened with 6.0.2 and earlier versions before I upgraded to FF7. OS is Win7 x64.

Oh, and it also happens when I start FF in safe mode (no add-ons loaded).

This is on my PC at work. It also happens on my girlfriend's PC (FF 7.0.1, Win7 x64) but NOT on my own PC at home (also FF 7.01 and Win7 x64).

Re: Firefox keeps loading pages forever... or stops loading pages

Hi mha007,

Now THAT has made all the difference. Thanks so much for that!!! I can buy stuff on ebay again .. ;-)

Would you mind explaining WHY that has helped, please? The default value was 256. Are these just too many connections? Isn't 30 a bit low now, seeing that the connections-per-server are set to 15.

Re: Firefox keeps loading pages forever... or stops loading pages

This value has been changed in Firefox 7. All earlier versions had value 30, that's why i asked you to change it to 30. You can try to use other values as well (just for checking purposes).

BTW i am also using Firefox 7 and i don't need to change the value to 30. I am using it with the default value 256.

Re: Firefox keeps loading pages forever... or stops loading pages

I just checked here at home where everything works. It is also set to 256. But this machine is much more powerful and has more memory. Could this have something to do with it?

I'm happy that it works now but I do like to understand the issue and the resolution... ;-)

Re: Firefox keeps loading pages forever... or stops loading pages

i did the about:config deal- absolutely no change. I've tried in Safe Mode with add-ons disabled but it stalls on SFGate and NYTimes. Tired of switching browsers all the time. I am going through the tedious business of switching to another default browser. I have been with FF for quite some time but the last few months have been very frustrating. I no longer trust them. The new releases in quick succession are IMO a bad idea.

Re: Firefox keeps loading pages forever... or stops loading pages

mha007: I just did the about:config suggestion... and it worked! At first nothing happened, but I noticed my MSN Messenger had a message about network issues... so I decided to give it a try when my ISP fix the problems... so a couple of hours later, the net was ok, and I checked Firefox, and it was just perfect... just the change of that value fixed everything...

Thanks a lot, I really mean it... IE crashed for nothing, it's almost a headache to use it, though it's a lot better than older versions.

But, there is still the question, how the change of that value affects FF? and, what I think it's even more important, why doesn't work ok (at 256) to everyone?

I really hope someone at Mozilla shows up, or at least, checks this issue....
