After Firefox has been open for a while and/or was used for a while, memory usage is at nearly 3GB. This happens both with e10s enabled and disabled, Firefox versions 52-54 at least. The number of tabs is between 8 and 20 (nearly all loaded), and there are many addons installed. The troubleshooting information is from this PC.

I have looked at about:memory and it is still inconclusive to me. I uploaded an anonymized one to here: https://mega.nz/#!nxIzwZYD!0V5b44D1Xfst4XlAPvbTEIVjRZXvgP6Y4Xs_jJkeeew

Hi,

You could also monitor Firefox in about:performance

  • Click the menu button New Fx Menu, click on help Help-29 and select Troubleshooting Information. Click the blue about:performance link.
  • Type about:performance into the address bar and press the enter key.

Doesn't help much, all addons perform well and only 2 tabs may be slowing down Firefox, one of which is about:performance itself... Besides, this appears to focus on CPU usage and frame rate
