Before to fix this problem I went into "about:config" and changed "browser.tabs.remote.autostart" setting to false and it fixed the problem. I went in and checked and it still says false but I have multiple processes. How do I stop them now? I can't use firefox if its going to keep using up all my memory and freezing up my pages.

Hi Dodi

Thanks for the screenshot. Something went wrong because you misunderstood. MOZ_FORCE_DISABLE_E10S=1 means that you need to create an environment variable with the name MOZ_FORCE_DISABLE_E10S and set its value to 1. You created a variable with the name Path and set its value to MOZ_FORCE_DISABLE_E10S=1 That explains why it didn't work.

Create a new environment variable: 

name: MOZ_FORCE_DISABLE_E10S
value: 1

You can remove the 'Path' variable you created with value MOZ_FORCE_DISABLE_E10S=1

Hello Bnice2me (I will),

Firefox will no longer let users disable multi-process (e10s) on the "about:condig" page .....

Please see : https://www.ghacks.net/2019/05/17/going-forward-multi-process-cant-be-turned-off-anymore-in-firefox/

And also : https://techdows.com/2019/05/mozilla-firefox-68-doesnt-allow-turning-off-e10s.html

Have you seen my post in this thread where you also posted (?) :

Hi McCoy, I received your email and would like to change the command line but confused on exactly how to do it. Using the command prompt I don't know how to get into installation directory and do I type the quotation marks in the line or not.

Thank you Dodie

Easiest is to use the Windows Control Panel and create an environment variable to disable multi-process.

  • Control Panel -> System -> Advanced -> Environment variables
  • MOZ_FORCE_DISABLE_E10S=1

That way it also works if you click a link in an external application (email).

Can you attach a screenshot that shows the Environment Variables panel in the Windows Control Panel ?
