Firefox 68.0 anyway to disable Multiprocess now?

Post by CalistoCoon »

I am not a fan of this feature and would like to know how I can stop it form working.

Going to about:config and using browser.tabs.remote.autostart and setting it to false no longer works.

Set environment variable MOZ_FORCE_DISABLE_E10S=1 to disable multiprocess.

How do I do this again? I don't want to mess it up.

I made an integer MOZ_FORCE_DISABLE_E10 and than set it to 1 and that didn't work.

It is an environment variable, not an about:config setting. Information is from here: https://www.reddit.com/r/firefox/commen ... tiprocess/
I do not know how to set environment variables.

Have you tried Options > General > Performance.
Remove the check mark for "Use recommended performance settings".
Change the "Content process limit" to "1".

@CalistoCoon

In Windows 7, run sysdm.cpl to open the System Properties window.

System Properties > Advanced > Environment Variable > New

Variable name: MOZ_FORCE_DISABLE_E10S
Variable value: 1

How to set environment variables

You can use the set command to create a temporary environment variable.

* open command prompt window
* change to installation directory
* type "set MOZ_FORCE_DISABLE_E10S=1" and press enter
* type "firefox.exe" and press enter

(64-bit Win 7, 4 GB RAM ought to be able to handle current FF, I'd think.
Isn't that Mozilla's mantra; fast, fast, fast ;-).
Disabling MP I'd think to be a wrong thing to do, generally.)

Disabling e10s means disabling sandbox, less security.

Hardware cant be such old running win7 x64.
