Bug 1565518, emergency preferences to turn off individual bug fixes: 1563695, 1556491, 1562315, r=kershaw!

Beta/Release Uplift Approval Request

• User impact if declined: Gives us a possibility to flip off individual changes (restore previous state) we want to uplift to release in case of major problems found during dogfooding/field testing/release.
• Is this code covered by automated tests?: No
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce: There are currently 4 bool preferences, giving combo of 16 possible configurations. Doing testing of all of them is excessive and not necessary.

Local testing on each of the pref was made.

• List of other uplifts needed: Bug 1563695, Bug 1556491, Bug 1562315
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Extremely low risk, this is nothing more then branching of code the way as it was before each individual patch based on a pref flip (read of atomic bool values). Note that this copies the pattern from bug 1563538, which is on Nightly/Beta since Jul 7.
• String changes made/needed: none

prefs for http2 proxying fixes, approved for 69.0b7 / 68.0.1 / 68.1esr

https://hg.mozilla.org/releases/mozilla-release/rev/5d966839d6dd

Change the status for beta to have the same as nightly and release.
For more information, please visit auto_nag documentation.

Per discussion with jcristau, we're uplifting this to 68.0.1esr also to maintain parity with the non-ESR 68.0.1 release and hopefully avoid some confusion.

default (68.1esr): https://hg.mozilla.org/releases/mozilla-esr68/rev/399e7261f098dbac19bdd10fadfcc869c970bb87
FIREFOX_ESR_68_0_X_RELBRANCH (68.0.1esr): https://hg.mozilla.org/releases/mozilla-esr68/rev/3c4fda3c06ecf69a3a9e3cd48d58a164c650980c

Do we need a bug for removing these prefs eventually?

Do we need a bug for removing these prefs eventually?

Yes, I will file one, but I'm not sure about a release to land it yet. I think we may need these, just in case, for a while. There is no big harm.
