I have my home page open and 8 processes (although in options -> performance I limited at four) and using 512 MB. What is wrong with Firefox Quantum?

I looked up for answers on internet and it says you can limit the number of processes if you go to Options -> Performance. I did and limited to 4 and it still goes up to 8. Also, and more bothersome, with just the home page open (and 8 processes in all), the total memory usage is 512 MB. It says somewhere that Firefox uses a lot of memory at startup but it's stayed the same for a long while. Each new version seems to use more RAM than the previous (unavoidable, I guess) but Quantum is presented as using less and is using at least twice as much as Chrome on my computer (according to Task manager), and yes I,m giving the aggregate of the memory used by the different processes with both applications.

Any ideas?

Hi, go to the 3-bar menu > Options (General) - Performance, then deselect 'Use recommended performance settings' and change 'Content process limit' to 1 - that should limit the number of processes you see in the task Manager to 4. See - Firefox's performance settings, and Startup, home page, tabs, and download settings.

If you are getting slowness; whilst in the 3-bar menu, you can also go to Options (Privacy & Security) - Permissions, and tick/check 'Prevent accessibility services from accessing your browser' then restart Firefox. More - What is the Accessibility Service Indicator?

Firefox might not run as smoothly, but if necessary, you can try turning off Multiprocess altogether: Type about:config into the address bar, press Enter, accept the warning, scroll down the alphabetical list to browser.tabs.remote.autostart and browser.tabs.remote.autostart.2 then double click on each to change 'Value' from True to False and restart Firefox.
