MAC OS 10.14.2 Firefox 64

Firefox continues to eat memory, whether used vigorously or just sitting. This causes the beach ball "wait" icon to appear for seconds when switching to/from another window or app or email

This one year old retina machine, with 8MB is slower than my 11 year old IMAC with 4MB

Try Low Resolution mode: https://support.apple.com/ht202471

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 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
