Hi Peter, Just wondering what version of Firefox you are using? - Newer versions seem to manage memory much better. Are you using CCleaner to get rid of all of the Firefox temporary files? - I find that this allows Firefox to run better with less memory issues, although it still uses a lot of memory Do you have a lot of Firefox Add-ons installed? - every Add-on takes up additional memory - you should only Enable Add-ons that you will use I have 2Gb of memory in my system and run many programs at the same time (i.e. Word, Excel, Firefox Outlook, Snag-It...), and have lots of Firefox Add-Ons that I use. Even so, I rarely hit 1Gb of usage. I do use a small freeware program called CleanMem Free (http://www.pcwintech.com/cleanmem) which allows me to monitor memory usage. A little pop-up box is always visible in the lower right of my screen to show me the memory status. A simple right-click on this pop-up allows me to free up any memory that has been inadvertently reserved... works very well... I also monitor memory and CPU usage with the Task Manager (CTRL + SHIFT + ESC). I have actually replaced the standard Task Manager with the SysInternals program called Process Explorer (a free Microsoft product). It gives a wealth of information. The only other issue I can think of right now is to insure that your HD is not too filled up... Any operating system will suffer from lack of space on the HD. Regards, Kevin.

I'm using version 7.0.1 with a few add-ons I think but can't remember what they are. I use CCleaner often and on my HDD I have 207 GB free of 465 GB. Perhaps I should install another 500 GB. I will download Process Explorer and see what that reveals.
