How do I reduce the CPU usage of Firefox?

Question

I use Firefox and I love it. Until now, I have had no problem with it, however recently I get messages saying that it has a very high CPU usage and my browser will freeze at random times, sometimes even when I only have one tab open. Does anyone know if there is an easy way to fix this?

Answer 1

There is a little add-on call Memory Fox, which when installed will help reduce the amount of CPU usage the browser uses. You can download the latest version, which is version 7.4, at the link below.

Also, tweaking your Firefox browser will help reduce the amount of CPU usage the browser uses.



First, check your add-ons. Go to Tools, then add-ons and in the "Extension" tab uninstall or disable any add-on that you don't use. This includes Java Quick Starter and Microsoft .NET Framework Assistance.



Second, while in add-ons, go to the "Plugins" tab and disable any plugins that cause your browser to slow down. In particular these tree.



-Adobe Acrobat, which bring up PDF files from websites onto your browser. Turning it off will prevent this and your PDF files will open externally.



-get Plus for Adobe. This is not needed.



-Java Platform



-Java Deployment Toolkit (any version)



-MetaStream



-Microsoft DRM



-QuickTime Plugin, which allows you to view QT video on websites



-Realtime HTML 5 Video Shim Plugin



-Shockwave for Director



-Window Media Player Plug-in Dynamic Link Library



and finally, Window Presentation Foundation.



All of the above is not needed.



Third, you can tweak Firefox to run faster on your computer. The link below is video on how to do it.

Don't forget to restart Firefox in order for the changes to take effect.



Fourth, if you download files into your computer, go to Tool then Download and delete to files from the download list.



If you don't want to have any download file in the status bar in the future, go to Tools, then Option. Click on the "Privacy" icon and unchecked the box that says "Remember Download History."



Finally, always, always clean out your recent history, that way Firefox can work faster. Try doing every two weeks or every month, it's up to you. If you don't how to clean out your browsing history, the video link below will show you how.

Answer 2

How much PC ram do you have?

Also do you have any other heavy programs on the background ( e.g Anti Virus Scan/Torrent Download/Desktop effects etc.



If that's not the problem, I would advise you use a Great Program, known as Ccleaner, which basically deletes all the unneccesary junk from your computer, If your computer is still pretty slow..I guess you have a very old computer which you should upgrade or you are infected with a virus.



I post link of program and a good antivirus:

Make sure you're on the latest version, and uninstall any extensions that you don't really use. Apart from that, I'm not sure why FF would exhibit unusually high CPU usage with only one tab open, unless that tab featured some pretty heavy-duty HD video or something.
