How To Solve 100% CPU Hogging by Firefox in 2 Steps

Sometimes FireFox crashes. I don’t know why this happens and I meant it “constantly” I am so confused about it. Can you guys help me out?

I was looking for some ways to get me better updated on firefox browser. But for some reasons I quit using firefox for it constantly crash. I use Google Chrome and am very much satisfied with it.

I hope getting out of Ocracoke was not necessarily needed and Earl juststays out at sea. Let us pray for that.

It is a nice little extension which simply displays a play button instead of Flash ads. If you wish, you can play the Flash content by clicking on the play button.

Thank you very much for posting a lot of this excellent info! I am looking forward to seeintg more posts.

Do not cash to buy a car? Worry no more, because that is possible to take the credit loans to solve all the problems. So take a student loan to buy all you require.

I used to have Firefox hogging the CPU within a few hours after starting it, however I soon realized the culprit is Facebook. Apparently the JavaScript on Facebook hogs Firefox for some reason.

I resolved this by blocking scripts on Facebook, which unfortunately makes the site unusable, so I now use Chrome or IE to access it, and keep using Firefox for the rest of the sites.

I can have literally hundreds of open tabs on Firefox with only 3% CPU usage at most, as long as no Facebook Java scripts are running.

Well I’m running Windows 7 64-bit with 4GB of RAM on a dual core Pentium and Firefox is still crap on this. It’s okay until I leave the PC to do something else and let it go to sleep. After I wake it up it’s a 50% hog. It’s worse than Internet Explorer!

The developers are hopeless and lazy about dealing with this and I’m close to giving up on it and trying something else. Opera used to be good but now it’s just been wrecked by the geeks and not as straightforward as it used to be, Avant looks like IE in a different disguise, Chrome is okay but it doesn’t save tabs. So… I don’t know.

I experienced the same problem on an E6800, 4gb DDR2 mem, Xubuntu 10.4. I tried out the google Touchgraph java applet; after closing it, and for about 5 minutes until I figured out that’s what it was, firefox+java absolutely hammered both cores. The solution was just to kill Firefox. Now with Chrome supporting extensions, it’s starting to become feasible to just use something else, such as Chrome, over Firefox.

Anyway, java was definitely the culprit for me.

thanks for the tips, I would also like to add that disabling AVG addons descreased Firefox’s CPU usage dramatically! Fireforx went from 44% CPU usage to 0~1%!

THANK…YOU…. this was pissin me off, simple solution. Works perfect.

Flashblock requires java to work, right?
So doesn’t step 2 wipe out step 1?

many thanks for your post. this has been getting at me for a few weeks now.

Another way is to uninstall the crappy thing.

I had same problems with CPU running at 100% with or without internet.
Action:
Fan keep CPU cool was plugged. Open up computer (while power was off) and cleaned out build up of dusk all over the fins of cooling fan covering CPU. Now CPU is running from 3-20 %. May go up to 100% just for one second.

I think some of you people need to get out more. The guy is just offering a suggestion that worked for him, stop complaining if you don’t want to use it - don’t.
Ultimately there is so much guesswork with FF (much as I love it and use it on all machines and OS’s) is because there are so many incremental changes that render toolbars, add-ons and extensions incompatible or troublesome. Its difficult to tell what the underlying problem is because it might not be same on version x.x.x.x.1 as it is on version x.x.x.x.2.1. The Mozilla guys are superstars but they have proved their point, now please release fewer and more stable properly tested versions guys.

Different fields of life take a lot of time and money, thus why must we waste free time for sample essay creating? That is easier to utilize some famous essay writing service to purchase the argument essay from, I opine.

Lol - so your solution to flash players hogging the CPU is to *not* view flash video? That’s hardly a solution.

Switch to Chromium: Using the same version of flash (10.0r42) in both Firefox and Chromium in Ubuntu, Chromium outperforms Firefox on all flash sites I have tested. And not just by a small margin. I have a lowly AthlonXP 2400+ and Firefox uses 100% on all flash enabled sites whereas Chromium has a brief burst of high CPU use then it goes back to normal - this makes all sites usable again for me.

None of these solutions work. Aren’t we all tired of guesses from people who think they know everything about computers? Everytime we have a computer issue we have to wade through a thousand different sites with guesses from self proclaimed computer experts. If you haven’t personally duplicated and fixed this exact problem on several machines than shut up. We don’t want to waste our time trying a million things hoping one will work. Only offer a solution if you are sure it will work. We don’t care if you say “Well this works for me!”. Obviously you have a different problem than the rest of us because this issue is still happening. Your advice didn’t help. The Intertubes are littered with this kind of pseudo-computer-guesswork and we are all tired of reading it all and wasting our time. Flash still uses 100% CPU cycles after all of these guesses were tried.

better solution is deleting any file starting by the name firefox in c:/windows/prefetch

it reduces your FF usage by 20-30%…

this is not realy a soluction… disabling flash? desabling javascript? why not just start browse in text mode?

I am getting the same exact problem with version 3.5.3. and I thought Firefox was going to take care of it!
