Comment 5

[BugBot [:suhaib / :marco]]

The patch landed in nightly and beta is affected, along with ESR.
:sajidanwar, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta and ESR approvals.
  • See https://wiki.mozilla.org/Release_Management/Requesting_an_Uplift for documentation on how to request an uplift.
• If no, please set status-firefox154 and the ESR status flag(s) to wontfix.

For more information, please visit BugBot documentation.

Comment 6

[Sajid Anwar [:sajidanwar]]

Hmm, I'm not sure why this is marked as affecting versions before 155? The original regressing patch only landed on 155. Going to clear out the statuses for the other versions, hopefully that's OK.

Comment 7

[BugBot [:suhaib / :marco]]

Set release status flags based on info from the regressing bug 1827404
