waiting if jim is getting to popover stuff

Marking as quantum flow p1 because this is about the ability to run webextensions in a seperate process.

I went through the Quantum Flow release criteria and I don't believe Linux is a blocker for that. So taking off the :p1 designation.

Nightly 56 x64 20170706100310 @ Debian Testing (Linux 4.9.0-3-amd64, Radeon RX480) extensions.webextensions.remote;true works now (I have stylo enabled), but panels have fat black (webrender:red) borders, which is okay for testing dom.ipc.processCount.extension;2 does not work, no addons are loaded then, I will wait patiently

There is a problem with OOP Webextensions inside locationbar if the otherwise perfectly working GPU Process is enabled (for example for having some more stability while testing WebRender). This might not be a blocker for this bug because the GPU Process is currently disabled by default on Linux.

We mentioned that change in 61 release notes for macOS, therefore I'll add a note in 63 nightly notes with the same wording: WebExtensions now run in their own process on Linux

Backed out changeset ef1550969466 (Bug 1357487) caused perf regressions & author didn't justified them. Push with issues: https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&revision=ef1550969466fbe9049ee922735f020af82f66d6 Backout link: https://hg.mozilla.org/integration/mozilla-inbound/rev/ed6567a175dd6a9b9de58b8867f03db7a17ee330

Note about this feature disabled from nightly 63 release notes following the backout.

BTW enabling extensions.webextensions.remote also disabled Firefox' JSON viewer on the manifest.json. I doubt this is intended. See bug 1481012 for a related issue/problem with the JSON viewer for WebExtensions.

Verified using Ubuntu 18.04 and FF Nightly running on latest build as of (04/08/2018). As the feature has also been validated previously, will be closing out this bug as well.
