1652134 - Add Fission Feature Gate to about:preferences' "Nightly Experiments" section

Status: RESOLVED FIXED

(Firefox :: Settings UI, task, P3)

Description

[Chris Peterson [:cpeterson]]

(Fission probably won't be ready to be listed in the Experimental Features section until August or September. This bug is a placeholder reminder for the Fission team.)

We will need to add Fission to toolkit/components/featuregates/Features.toml. See https://firefox-source-docs.mozilla.org/toolkit/components/featuregates/featuregates/index.html for instructions.

Features.toml entry schema:

restart-required = true
preference = "fission.autostart"
type = "boolean"
is-public = true
default-value = false

We'll also need to add Fission documentation to MDN's Experimental Features page:

Deferring to Fission M7 Beta because listing Fission to Nightly's Experimental Features UI doesn't block running our A/B experiment.

Comment 2

[Chris Peterson [:cpeterson]]

Moving back to Fission M6b because we'd like to promote Fission in Nightly's "Nightly Experiments" UI before we run our Nightly A/B experiment. Our current plan is to fix this bug near the end of August.

We don't want to show Fission in the Nightly Experiments until the end of August, so maybe don't land until Fx82 Nightly starts on August 24?

We want to fix some more stability bugs and finish Fission session history (meta bug 1467221) first.

No worries, I had this in my triage queue and figured I would just write the patch as a fast way to clear it from my queue ;)

Waiting for Fission printing (bug 1480547) and session history (bug 1467221) to be fixed before we land this patch.

Don't need to block on printing but definitely on session history.

[Chris Peterson [:cpeterson]]

Note that we're adding some new Fission prefs (in bug 1660057) to support our Normandy experiment, but Nika assures me this checkbox patch still only needs to read/write the fission.autostart pref. So no changes to the current patch should be needed!
