Hi  !

Did you do this  :

Type in the address bar about:config   (press Enter) (promise to be careful, if asked)

Type and search for the preferences :

browser.tabs.remote.autostart and set it's value to false (default)

browser.tabs.remote.autostart.2 and set it's value to false

Then close and restart Firefox.

Note: the exact name of the preference may vary, but it will start with browser.tabs.remote.autostart

OK, I finally realized I was entering about:support not about:config. Big difference. Got it changed, now I'll see if it helps performance.

Note that you can also experiment with the number of content processes.

What kind of performance issues do you have?

Did you try Firefox Safe Mode?


You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Now that I have e10s set to false, it seems to be better.
