Firefox Is Slowing Down My PC
 

Recently Firefox has slowed my pc down and at points it has stopped for a minute or two. When I click bookmarks it halts and then I try again and it works.

My PC is 1GB, 2.4Ghz processor, Win XP SP2, all patches.

Can someone help as I do not want to format.

Re: Firefox Is Slowing Down My PC
 

Try disabling extensions one at a time to find the cause of the problem.

Re: Firefox Is Slowing Down My PC
 

As Rich says, disable extensions and any themes running and see what happens. It could be a corrupted extension or theme causing a problem. Also, ctrl+alt+del and check your memory and processor usage when things bog down.

Re: Firefox Is Slowing Down My PC
 

I have tried that and the only extension I have left is the CF one and I have taken it off and put it back on.

Just been watching the performace graph in task manager and I have got next to nothing running so I think it is something pc related. I am going to track it this evening and I might reformat as I've been runnnig this setup since the end of May.

Re: Firefox Is Slowing Down My PC
 

Try booting firefox in safe mode (there should be an option to do so under All Programs > Mozilla Firefox.

This will boot firefox in safe mode - not using any extensions or extra themes.

If it runs fast(er) on safe mode, try uninstalling some of your extensions - or, as Richard says, disabling them one at a time.

If you find the pages aren't loading as fast as you would like it to - try using this little trick.

This will enable your pipelining for http requests, proxy requests and it will change the max requests for the pipelining to 30.

Hope this helped.

Performance graph? It's probably easier to pinpoint problems by watching the process page, you'll be able to see exactly what process is using the processor or RAM heavily when your system is crawling.

Re: Firefox Is Slowing Down My PC
 

Explorer.exe is using the most in the task manager. I think its an issue with my pc so I am going to format.

Re: Firefox Is Slowing Down My PC
 

Strange, when it all slows down the only thing using any significant amount of RAM or CPU is explorer? Are you running any themes/ skinning software etc or have any third party apps installed that could be affecting explorer?

Re: Firefox Is Slowing Down My PC
 

I did install some theme/skining software and I uninstalled it and after that my pc slowed down. The themes are still in the list and I did install that file from Neowin that allows you to do it. Is this what is causing the slow down?

Re: Firefox Is Slowing Down My PC
 

Could be a problem with explorer caused by the skinning being done/ undone. Is explorer the only thing hitting your resources during the slow downs though? If it is then you may be best off formatting to get your system back to a clean and healthy state again. It may not be needed though.

Re: Firefox Is Slowing Down My PC
 

I'll format, its not going to hurt anything and will give me something to do and clean my system up. Been 4 months since this setup was installed.

Thanks for the advice about the extensions which could of saved me time but this time it wasnt.

Re: Firefox Is Slowing Down My PC
 

I've had Firefox go into suspended animation when I bookmarked a page that was over a VPN link. Every time I clicked on 'bookmarks' and moved the cursor down the list, it would stop for ages on one particular folder. Inside was the bookmark to another PC over the VPN tunnel.

It could be something similar. Take a copy of your current bookmarks in 'Windows\Application Data\Mozilla\Firefox\Profiles\summat\bookmarks.htm l'. Then try deleting some of your recent ones.

Re: Firefox Is Slowing Down My PC
 

Clear the history.

Re: Firefox Is Slowing Down My PC
 

It's not browsing that is slow its the actual program but I've narrowed it down to been my computer.

Re: Firefox Is Slowing Down My PC
 

how about a quick disk defragment and clean up

or use one of those system utility from download.com

Re: Firefox Is Slowing Down My PC
 

Tried defrag and cleanup.

What sort of system utility do you recommend?

Re: Firefox Is Slowing Down My PC
 

Run a good disk degrag with Diskkeeper 9 executive ( cost a bit but well worth it. )

Re: Firefox Is Slowing Down My PC
 

Found a copy of Diskkeeper on Download.com I will give it a try now.

Has it done anything in windows?

Right another if you have removed anything to do with Firefox or possibly something else, try and get a registry cleaner software and run that, also I assume you have done spyware scans like normal and anti virus.

May be worthwhile reverting Firefox to default values where you can in case something has gone amis?

Re: Firefox Is Slowing Down My PC
 

I have done a format and used the MozBackup feature and I think the thing that is slowing down FireFox is my profile so I will create a new one later on and see if that solves it.

Re: Firefox Is Slowing Down My PC
 

Profile??

I am using Firefox just as it was out of the tin with only a theme added to match my windows one?

Re: Firefox Is Slowing Down My PC
 

Your profile is what retains all your firefox settings.
It may have got sorrupt so its a good idea to try creating a new one.
Good luck.

Re: Firefox Is Slowing Down My PC
 

Fixed it, just removed and tided my book marks up a little and it seems to be ok touch wood. Odd really.

Re: Firefox Is Slowing Down My PC
 

Now what did I tell you? ;)

Glad you got it fixed :)

Re: Firefox Is Slowing Down My PC
 

altis must of overlooked that one.

Re: Firefox Is Slowing Down My PC
 

Glad all is working for you again.
Sometimes a small thing can cause a thousand problems. Its good you finally found out what it was.

Re: Firefox Is Slowing Down My PC
 

Talking of causing problems I have lost data when wiping, did back it up to a DVD but never checked it restored properly! That's another thread when I get around to it.

Re: Firefox Is Slowing Down My PC
 

I had the same problem with Windows and Firefox, turned out to be the downloads (Tools/Downloads) which I hadn't removed (Cleaned Up), seems Firefox keeps them in memory until you press the Clean Up button, eventually brought the whole system to a crawl. I have never had the problem with the Linux version, but then it's not Microsoft Linux :dig:
