We can't ship it on Release until storage initialization failures are addressed.

Only c3 on win debug failed and that can be easily fixed by increasing the number of expected assertions, like in bug 1581722.

Bug 1606781 - Disable LSNG in 72; r=asuth

Beta/Release Uplift Approval Request

• User impact if declined: If LSNG is enabled, LocalStorage depends on QuotaManager storage which is currently broken for some users. We don't want to ship LSNG until the issue is fixed.
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): This patch just disables LSNG, so the old implementation of LocalStorage will be used in FF 72. We fully support downgrading of LocalStorage data, so if some users already tried a beta build, they should be safe. We disabled LSNG in previous beta cycles and there were no problems reported after the switch.
• String changes made/needed: None

I requested an approval before actual r+, so please wait a bit, thanks.

I talked with :asuth yesterday and he agreed that we are going to disable it in 72.

The same changes were reviewed in bug 1594299 and bug 1581722, I think that's good enough; approved for 72.0-build4.
