Memory Fox Manages Firefox’s Memory Use So You Don’t Have To

Firefox with Windows only: While travelling the internet, sometimes we don’t realise how much memory our browser is hogging until it starts acting sluggish, hangs or crashes altogether. Firefox extension Memory Fox optimises your memory so you can surf without slowing down.

Memory Fox keeps an eye on your browser’s memory usage and notices when Firefox starts edging toward user-preset resource limits. When it does, the extension springs into action, automatically flushing your memory to recover space and keep your browser from slowing down.

To use the add-on, you need two things: A Windows operating system and Firefox 3. Once you download the tool, restart your browser then activate Memory Fox from the Tools button in the toolbar. Now the add-on is all set up to flush the memory every time you open or close a tab, or switch between tabs.

Memory Fox may not make a noticeable difference in your browsing speed if you’ve got a souped-up computer, but it’s a terrific add-on for machines without a lot of extra RAM to sacrifice to the ‘fox. It’s an experimental extension, Windows only. If you give it a try on your memory-hungry Firefox installation, let’s hear how it works out for you in the comments.

  • Seems to work for me, it has reduced my memory usage from over 900,000k (approx) down to under 200,000k (approx), the pages are loading the same and physical memory down from 93% to under 40%. So happy so far…thanks
