Find Out Which Extension Is Eating Up Your Memory In Firefox

Find Out Which Extension is Eating Up Your Memory in Firefox

Firefox: Extensions are a great way to augment your browser experience. They're also a great way to balloon your RAM usage if you're not careful. Here's how to find out which one is grinding your system to a halt.

As of version 24, Firefox has the ability to see exactly how much memory each extension is taking up without installing yet more add-ons to analyse their usage:

  1. Navigate to about:support.
  2. Copy the ID of an extension you want to check.
  3. Navigate to about:memory.
  4. Click "Measure" under "Show memory reports".
  5. Press Ctrl-F and paste the extension ID.

This should show you exactly how much memory a particular extension is using up. It's not the most intuitive thing in the world, but if you're having a problem with a particular extension and aren't sure which, it's a simple way to find out.
