Firefox frequently freezing

Asked by Luis Jorge on 2007-08-27

Hi everyone!

I've noticed some problems with Firefox lately. Especially when on YouTube or Either watching a video or just surfing through programs and projects in sourceforge, sometimes firefox just freezes when "loading" a page, or if I close the window or tab on youtube. I have to click "force quit" to be able to close it. This happens quite often, but it didn't before and haven't changed anything in the configuration. I reinstalled the Flash plugin yesterday, and apparently this problem doesn't happen anymore on youtube, but still does on sourceforge.

Any help would be greatly appreciated! I'm running Ubuntu 7.04 on a Dell inspiron 630m notebook. If more information is needed, please tell me.

Thanks in advance!!

Luis Jorge.

go to firefox help, about mozilla firefox and look at the bottom mine reads:-
Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20061201 Firefox/ (Ubuntu-feisty)
I had to run the upgrade from firefox page. all ok now

May i ask you to type from Applications->Accessories->Terminal:

sudo apt-get-clean
sudo apt-get update
sudo apt-get upgrade

This is what i do to get ALL the updates for the system.

I don't think downloading Firefox directly from Mozilla site, is the right Ubuntu way to update and keep updated your Firefox browser (and your system).

Hello again!

Thanks for the quick replies! But, unfortunately, I couldn't solve my problem...

Dave, I checked my firefox, and it says exactly the same that yours. I think is up to date.

And elart, I did all that in the terminal, but it said it did 0 upgrades and 0 new installs...I think everything is up to date as well, right?

Thank you very much for the help anyway, and please let me know if you have any idea, or if you need more information!

Luis Jorge.

Thanks for the tip, Cesare. Well, I checked that bug, and it sounds very similar, though my whole system doesn't freeze (just firefox, not even X), and I already had the cache-clear every time I closed firefox, so I still don't know if there is a way of solving this. Today I had about 5 freezes in 30min, when using both tabs and flash content, and even multiple FF windows, but it has happened once or twice with just one window and no tabs.

This didn't happen before, but I don't know before what, because I haven't changed anything.
Also tried to reinstall firefox twice: The first time, synaptic said FF was being affected by some bug, and that with the new install should be gone. The second, everything went fine, no bugs, but the problem persists.

Please tell me if you need more information about anything.

Thanks in advance,

Luis Jorge.

Seems different then, on top of what is suggested in that bug in my case I also had to disable JavaScript.

I've been having the same issues. In firefox and also in seamonkey.
However, these folks seem to have something figured out. Perhaps it's an issue related to flash and flash plugins for mozilla.


Jeff (grapnell) said : #8

Mine is still freezing regularly... and its a month later...

Kato (temp2-emails) said : #9

Mine too : ( Using ff and flash 9

Please try the Firefox3, now in beta beta2, may solve this.
Please open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo apt-get update; sudo apt-get install firefox-3.0

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this help

I have a similar problem -- see #19181. I have suspected it was attributable to a barely effective wireless network adapter, but from the variety of the responses to this problem I am beginning to suspect that it is due to installing UBUNTU on a 64 bit system. I'm using an Intel Core 2 Duo. Recently, I purchased 2 Intel PC's, PIV's running at 2.66 GH,with 512 MB of RAM, and 20 GB hard drives for $30 each. (Our local Dept. of Transportation had a sale.) I installed UBUBUNTU on both of them with no difficulties, and surfed the web extensively with both of them. I have a DSL modem. One of these PIV's I ran wired and the other I ran wireless. Firefox behaved flawlessly.

Same problem here. Using:

Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv: Gecko/2008092510 Ubuntu/8.04 (hardy) Firefox/3.0.3

I'm pretty sure the problem occurs when Flash access the network. Eg. it happens when YouTube is buffering video or with flash applications, that call home to a server. The entire browser freezes. If I wait long enough (about a minute or so), it comes back.

Due poor integration of proprietary flash with Linux you may want to install also the mozilla plugin Flashblock
to block flash into web pages to get better Firefox and general pc performance
you may install it using mozilla here:

Hope this helps

Also I have the same trouble with the javascripts that freezes firefox. I use another add on noscript to disable these javascripts along with the flash elements. Firefox will not feeze anymore but it is irritating. Hope that a future release will fix this problem.
I am using Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/2008121622 Ubuntu/8.10 (intrepid) Firefox/3.0.5 Ubiquity/0.1.5

I have the same problem, however it was prevalent when runing Windows Vista Home Edition. Now I'm running Linux Mint XFCE Ver 6 and the same thing. The only thing i was relating this problem to was the DELL hardware, or video cards. I don't believe that this is an OS platform problem. Still trying to figure out.

Greg (llongtine) said : #16

P.S. My home page is Linux Mint with zero flash / eye candy. Will start to go grey and freeze for about a minute. Go figure I'm stumped

todji (tgoglia) said : #17

The problem is definitely with Flash. Firefox was freezing up for about 30 seconds every 10 minutes or so. I installed flashblock a couple of days ago and have not had a problem since.

The problem seems to occur when you have multiple tabs open that contain multiple flash objects. It happens to me when I'm reading online newspapers or journals where I open individual articles in new tabs.

I've posted this on an ubuntu thread also but here goes:

OK so I've been fighting this problem for several weeks. No one seemed to know why firefox would freeze in Ubuntu 8 and 9. I figured it out by running firefox in debug mode. "NSPR_LOG_MODULES=all:5 firefox"

Every time firefox froze I would see "resolving". So I tried the usual ping, nslookup and the results were very inconsistent. Sometimes it would resolve but mostly just time out.

After a little googling I found out that firefox has built in Google Safe Search that frequently communicates with

So I disabled this safe search feature and NO MORE LOCK UPS!!

You can disable This safe search feature by going to Edit - Preferences - Security, uncheck "Block reported attack sites" and "Block reported web forgeries" .

Hope this helps some of you, it was very frustrating for me.

rebroad (rebroad) said : #19

I was getting this problem too. Even with flashblock running. I've since started using OpenSUSE 11.2, running Firefox (3.5.5) under KDE, and have had no problems so far. So I suspect it's either a problem with gnome or ubuntu.

Things to try next would be Firefox under KDE on ubuntu, or Firefox under gnome under OpenSUSE.

PS. I was getting this on the latest Ubuntu 9.10 (64bit), but also on previous versions going back to Ubuntu 7, 64bit and 32bit.
