Multiprocess won't enable with addons enabled, even though the addons are compatible.

I can't get electrolysis/e10s/multiprocess to not be disabled by add-ons. Running on Debian.

So, I upgraded to FF50 (From the Debian unstable repos, 50.0.2 according to the repo and the about: page), and flipped the about:config key browser.tabs.remote.autostart to True.

Looking at the "Multiprocess Windows" field at the about:support page it tells me that it's enabled properly, with all my addons disabled.

But if I enable any addon (I've tried with every addon installed that the compatibility reporter tells me is compatible, you can see a list in the troubleshooting information) and restart the browser, the about:support page tells me that multiprocessing is "Disabled by add-on".

From reading at the mozilla wiki (https://wiki.mozilla.org/Electrolysis) and generally around the web, it seems that from version 50 and on, e10s should be working with add-ons as long as they are multiprocessing compatible, which the Add-On Compatibility Reporter (https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter) tells me all of my add-ons are. (Except the DOM inspector, which I only enable when I need anyway)

Is there something I have overlooked? Something more that I should try?

Troubleshooting information is with the Add-On Compatibility Reporter enabled, and all other add-ons disabled.

Also, I'm aware of the force enable option, I'd just like to try and see if there's a problem that causes this or if it's just a weird bug. If there's a problem that disables e10s, there's probably a reason for doing so, meaning a reason not to force enable.
