When Firefox came out, we were all so happy about its speed and nimbleness. As the browser has matured, its become a bit of a memory hog what with all the add-ons and improvements. I’ve been hearing Steve Gibson of Security Now speak about it several times in the last couple of months, so I thought I’d check it out. If you’re running Firefox 6, I’ve heard this browser version is the worst. The new version 7 is supposedly much better.
First, you’ll want to see for yourself how much memory Firefox is using. Mozilla has made it easy. Simply type about:cache in the URL bar to get a look at your current memory situation. I have 4GB of memory on my machine and I just had logged off and back into my computer, so you can see my storage in use was very low after doing this. Try it after you’ve had your browser open and going for a few days and see what it is.
Things to Do to Speed Up Firefox
1. Close your browser and reopen it. Simple, but effective.
2. Reduce the session history number. This setting keeps track of all the pages you’ve visited and this number can be safely and easily reduced. The default is 50. I changed mine to 25. To do this, you’ll first type in about:config in the Firefox URL bar. You may get a warning, just click OK. Then hit Ctrl + F (find), and type in “browser.sessionhistory.max_entries” and you’ll see it as I have pictured below. Right-click on the line and select ‘modify’. Then type in a number.
3. Go through your Add-ons, Extensions and Plug-ins and delete the ones you’re not using or no longer need. To do this, hit Ctrl+shift+A and you’ll be taken to a screen where you can go through all of these and just remove the ones you’re not using. I found quite a few add-ons I deleted.
4. Set Firefox’s max cache size. This can be a bit risky, I’ve read. I prefer to let windows take care of how much memory is used for anything I do.
Now you can check how much memory FIrefox is using and take some steps to reduce all the memory being used. Good luck and if you have found other solutions, please leave a comment.
