Reducing memory usage in FireFox
Posted On July 30, 2006
Learn how you can tweak your Firefox application to consume less memory and work little faster.
I’m crazy about this browser right from the day of release. Firefox bought me in a change of browsing style. I really love this tool. But only concern I’ve about Firefox is its memory usage. Hope this would be the concern for other users as well as the Firefox developers. It sucks most of the memory space. I’d say Firefox is memory ravenous compared with IE.
Firefox has lot of memory leaks and that has been fixed the most in the latest release. Anyway that’s not our part Mozilla developers will take of that If you think you can contribute better then join their team. Visit Mozilla today to find out more ways to contribute.
Now let’s optimize Firefox to use less memory and to work faster. This is the smarter way too.
Type about:config in the address bar.
- Create a new Boolean entry config.trim_on_minimize and set it to true (This one works gr8 when ever you reduce the FireFox window. It almost saves 20 MB – 30 MB+)
- Set browser.cache.memory.capacity to a fixed size (the default values are: for 256 MB RAM – 14336, 512 MB RAM – 22528, 1 GB RAM – 32768). This is free 22MB max.
- Set browser.sessionhistory.max_total_viewers to 0. It can reduce around 20 MB of usage
- Change image.animation_mode to none. It has little impact on performance.
Now go to Tools/Options.
- Set the disk cache memory to a low value (less than 50 MB).
- Turn off Java (If you really don’t use it).
- Try to avoid memory hungry extension. If you decide to use some; don’t use more that 5.
- Clear the download history now and then. Don’t let the list to accumulate. This will have impact on the performance.
Using these tips, I was able to reduce around 40 – 50 MB of memory usage. So why to wait try it today. Happy Browsing.
Try Firefox today if you didn’t had a chance yet.
