Firefox

When Firefox is open it uses all of the unused cpu what should i do?

I have run norton and ad-aware but nothing.

 

Are you running the latest version? Seems they had some issues with with version 5 and 5.1 and memory. Also what Firefox plugins are you running?

 

This is the version

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4.

And im running google toolbar and favicon packager.

 

No problems here, there is a known cure for memory hogging, but most probable cause in my opinion would be NORTON, nasty CPU and Memory Hog, as are most Symantec programs, but thats just my opinion

 

Sorry, just noticed my typo in my previous post. I meant to say version 1.5.0 and 1.5.0.1. Yes, you are current. And those plugins should not cause a problem. Have a look at this FAQ about firefox and memory usage. Lots of tweaks here and it may resolve your problem:

This is a common problem that you are experiencing (I experience it too). The most effective tool I've found for combatting this is this step (discussed in the link provided by itguy) :

Memory Usage Upon Minimize

There is a pref that enables trimming Firefox memory usage when you minimize all Firefox windows. This pref is for Windows only. To enable it, set the following pref to true using about:config:
config.trim_on_minimize

Admittedly, this treats the symptoms and not the disease. I have been working on solving this on my system for so long, that I have now resolved myself to simply hoping that the next ff release fixes this problem.

 

I don't have that option in about config.

 

I don't have that option either.

 

If you want to keep Firefox from using a lot of resources do the following:

1. Open Firefox
2. In Address bar type "about:config" (without the quotes)
3. Press enter
4. Right click anywhere, and select New--> Integer
5. Type "browse.cache.memory.capacity" (again without quotes)
6. Click Ok
7. Type in the amount of memory you want Firefox to use 16384 for 16Mb is appropriate, double that for 32Mb.
8. Click Ok
9. Restart Firefox

Hope that helps with "about:config"

You can add the pref if it's missing; right-click on the page, select New -> Boolean, paste or type in config.trim_on_minimize , set to True.
