Check or Clear FireFox Memory Usage

Firefox

FireFox makes it very easy to both check and clear your FireFox memory.

If you think your FireFox is getting slow or laggy, the best thing to do is close and reopen it but if you want a quicker way, do the following:

1. Type “about:memory” in the browser address bar (where you enter websites) and press enter
2. This will bring you to a page with options to “Show memory reports”, “Save memory reports”, “Free memory”, and “Save GC and CC logs.”
3. The first couple are especially handy if you want to debug memory usage. However, if you want to simply clear memory usage, click on “Free memory.”
4. This will immediately clear the unused memory and make your instance noticably smoother. If you want to reduce memory usage further, you can click on “Minimize memory usage” within the same panel.

That’s it! A quick and simple way to clean up RAM thanks to FireFox’s hidden options.

If you encounter RAM issues more often than you care to deal with, considering upgrading your RAM with some compatible high speed options.
