Every now and then, when I'm on Firefox it will not respond then the window will fill white and at the top it will say "Mozilla Firefox (Not Responding)".
It responds after about 10-15 seconds but this keeps happening every 2-3 Minutes and is making Firefox unusable to watch videos on Youtube and read other things as when it starts responding it take me back to the top of the page.
I cannot pinpoint which websites this is on but it normally (But not always) happens when I have more than one tab open (Usually on Youtube + SammyServers.com)
FireFox version: 3.6.12
OS: Windows 7 x64
I can't believe there hasn't been a response to this problem.
I recently formatted and the problem started a few days ago for me.
You start to download a file, download window pops up, everything freezes 'FireFox' stops responding... If you wait it out a bit say 10-30 seconds it comes back and everything is normal.
It happens randomly, it occurs doing different taks within the browser.
Surely FireFox development team must have some kind of idea what causes this? It's very very irritating.
Some help would be appreciated. Thanks.
I'm already sick enough of this problem over the past few weeks that I was ready to switch to Chrome, but thought that I would check Firefox support first.
If there isn't a fix soon, I'll definitely be switching. I've not had problems like this with Firefox before, but this is very disruptive.
places.sqlite (history stuff+favicons etc etc)
urlclassifier3.sqlite (google phishing url's, will be rebuild)
Must be somewhere in your profile directory...DELETE them.
I have this problem and it seems that "631" people have this problem aswell
Is anything going to be done about this? Or am I going to have to switch to a new browser? This has been happening to me for over two weeks and updating firefox has not helped.
I even tried what martign2011 had suggested and still have the problem. I did not see a 'urlclassifier3.sqlite' in my profile directory so I am assuming that it's not the problem.
I hope this gets fixed soon. I can't stand any other browser on the market. This problem is seriously delaying my projects. I'm almost out of time on one of them and this a huge disruption. I can't believe that this hasn't been fixed yet given how many people have clicked on here with the same problem. HELP! I NEED MY MOZILLA BACK!!!
OK, really? This is so annoying. Firefox has been so good all these years, and I have never switched browsers, but now it seems I am forced to. How can Mozilla not know of this issue ?? Has anyone with 7.0 tried revting back to a previous version? Even as I type this message, the white screen of non responding frustration comes up.... C'mon Mozilla, we want our Firefox back !
It must be frustrating if you suffer from this problem, and obviously many of you do, although there will be many millions of happy firefox users not seeing the problem.
This sort of problem may well have many potential causes. If you suffer from the problem then may I suggest you start your own thread and detail fully your problem and the troubleshooting efforts you have made.

If anyone is able to see this problem
Then it may be worth others trying to recreate it in the same circumstances, and file a bug report so that developers may review and fix the problem.
If you consider it appropriate post your own question , and if you think readers of this thread may be interested in the problem or its solution include a cross link in this thread to your new question.
I would not recommend deleting places.sqlite as a solution. Be aware if you do that all your bookmarks and history etc are at risk. Yes Firefox will try to rebuild places.sqlite, but it will be with older information.
If you do try that I suggest instead copying the file somewhere safe outside the firefox profile, that leaves open the option to copy it back if need be.
This thread may be of interest Mozillazine What is urlclassifier3.sqlite / page infos unusably slow
If you delete places.sqlite then you need to remove other existing places.* files like places.sqlite-journal as well to avoid problems.
Make sure that security (anti-virus) software isn't blocking access to files in the Firefox Profile Folder
