Additional notes

• Attached a screen recording.
• Note that this issue is occurring only on a Windows 10x64 and macOS 12 machine. I can’t reproduce it on Ubuntu 22 or on other Windows 10x64 machine.
• This also happens when the default browser is Chrome when opening the new migration window.
• This issue occurs once after a Firefox startup. The issue occurs again only after a Firefox restart or close/reopen.
• I am not aware of any functionality issues for this error.

:atrif, could you try to find a regression range using for example mozregression?

The bug is caused by the extension not having a description in its manifest.json file, see: https://robwu.nl/crxviewer/?crx=https%3A%2F%2Fchrome.google.com%2Fwebstore%2Fdetail%2Fi-dont-care-about-cookies%2Ffihnjjcciajhdojfnbdddfaoknhalnja%2F

The name is required but the description is not so we should account for that.

I don't think this is a regression since it's a new feature.

Based on comment #0, this bug contains a bisection range found by mozregression. However, the Regressed by field is still not filled.

:willdurand, if possible, could you fill the Regressed by field?

For more information, please visit BugBot documentation.

I don't think that counts as a regression since this is a new feature.

Verified fixed with Firefox 116.0a1 (2023-06-29) on Windows 10x64, macOS 12 and Ubuntu 22.04. I no longer see the error mentioned in the description.
However, an invalid manifest log is displayed on all systems after opening the Migration Window for the first time. Please let me know if this isn't expected and if we should file something against it.

This is the log.

That debug log statement is indeed expected, thanks!
