Standing up here means getting into a working but unfinished state. It’s a slightly uncommon turn of phrase, but it’s legit English.

To me it's very common in the tech community. Maybe a transfer from the embedded/sysadmin/DBA side of things, from what I've seen its usage move over time.

You aren't used to hearing about "standing up" new servers?

I must have written my text poorly, that's what I intended to convey; that in my experience the term's popularity started in the embedded/sysadmin/dba communities and then spread to the wider tech communities. Sorry! :)

I hear this phrase frequently in programming. In order to get your program running, you first have to make it stand up.

Is this the opposite of "stand down"? It seems to be.

I think its more like "to erect"; "to stand down" is more like "hold back", "disengage" or "retreat" (intransitive).

stand up (intransitive) ~= stand from a sitting or lying position

stand up <direct-object> == erect, build, appoint, enact

stand-up, upstanding (adjective) == moral, ethical

stand-up [comedian] == actually standing on ones feet

Computer jargon for "set up", likely from (US?) military jargon.

It doesn't yet work on fennec (regular Firefox for Android, which is non-e10s). Instead we're working on it for geckoview.

To add to this - this means it could be enabled in focus/klar nightlies, except they don't have an about:config page. You can build it from source, though!

It's very early days currently so you're not missing anything, but as it gets more stable I'm sure it'll be easier to try out.

I keep wondering about GeckoView vs Fennec. Surely Fennec already contains something much like GeckoView, so what will the difference be and when will (Nightly) Fennec switch?

GeckoView and Fennec share the same Gecko code, but GeckoView provides an embedding API for other apps and has some runtime differences like enabling e10s (sandboxed content process separate from the app UI). GeckoView-based features (like e10s and WebRender) will eventually be folded back into Fennec.

Me too. A bit of Googling told me that if you set the variable MOZ_WEBRENDER=1 it enables it. That worked.

That doesn't seem to work

I haven't tried these instructions, but the Android WebRender bug:

https://bugzilla.mozilla.org/show_bug.cgi?id=1453367#c13

says to download the "geckoview_example" app's APK:

https://queue.taskcluster.net/v1/task/AY-d7ns9QOGZuFj3syrsDQ...

and then remotely launch the geckoview_example app from a connected desktop machine:

  adb shell am start -n org.mozilla.geckoview_example/.GeckoViewActivity --es env0 MOZ_WEBRENDER=1
