Details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180303100406

Steps to reproduce:

1. Open about:config and set browser.tabs.remote.autostart and browser.tabs.remote.autostart.2 to false
2. Restart browser
3. Install an extension to suspend tabs, which uses tabs.discard() API. For example: Discard Tab (https://addons.mozilla.org/en-US/firefox/addon/discard-tab/)
4. Right-click on some tab and select "Discard Tab"


Actual results:

Selected tab is not suspended (when coming back to inactive tab, it's opening instantly). 


Expected results:

Selected tab should be suspended (when coming back to inactive tab, it's loaded back from scratch).

This disables e10s.  discard only works with e10s enabled.
