I just updated to Firefox Quantum to test it if I can migrate to firefox from Chrome. However during my memory test I encountered a problem. I had exactly the same extensions, exactly the same information (imported from Chrome) and exactly the same tabs opened in both browsers. Somehow, even with the Quantum improvements Chrome used about 1.4gb of RAM and Firefox used 1.6gb of ram. This test was done with just 10 tabs opened. I usually have 20 or more tabs opened in my browser and if this issue scales it would eat too much ram. Any ideas why this is happening ?

That is about my range 800 - 1500MB

You could try this please : Go the Menu then Tools --> Options --> Performance and untick everything. change the recommended size lower then see how it runs. Hardware Acceleration might have also been a issue so turn it off. Run it later and see as you turn things back on/off and test it, and again. Restart Firefox after making these changes please.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
