Comment on attachment 8892677 [details] Bug 1386457 - Export Screenshots 10.10.0 to Firefox Approval Request Comment [Feature/Bug causing the regression]: https://github.com/mozilla-services/screenshots/issues/3257 [User impact if declined]: A hard-to-reproduce race condition between the web extension starting and Shield putting the user in a cohort. Appears mostly with slow session restores (browser is upgrading, or user has lots of tabs, etc.). [Is this code covered by automated tests?]: No [Has the fix been verified in Nightly?]: Screenshots & Release QA have verified the Try builds. [Needs manual test from QE? If yes, steps to reproduce]: No [List of other uplifts needed for the feature/fix]: None [Is the change risky?]: It's a low risk patch [Why is the change risky/not risky?]: This prevents the web extension from trying to load twice and breaking itself [String changes made/needed]: None
