Newly created private tab stuck
This started happening after updating from FF52 ESR to FF56.0.2 Sometimes, when using the main menu to open a new private tab, possibly when the browser is under load, a stuck inaccessible new tab is created.
- not marked as private (no dotted underline)
- does not gain focus when created
- does not respond to clicks or attempts to close it
- happens both when e10s is turned on and when off
I haven't had the browser console open when the tab was created, but whenver I hover over it, I get
[Private Tab] getTabPrivacyContext() called for already destroyed tab, call stack:
