After I upgrade from 56.0.2 to 57.0.2, I found that every time I wake computer from sleep status the memory will increase a lot. For example, the usage of the whole computer was 11.6GB before sleep, but increase to 17GB after I wake it up. I have to restart the firefox to solve the problem. In addition, I also found after I delete the browsing history, both memory and CPU usage will increase rapidly and continuously. The other thing is the previous version, I suffered serious memory leak problem and get fixed in the version 57.

If you use Adblock Plus then you can consider uBlock Origin as a replacement to see if that works better (lower memory footprint).

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
