Bugmasters/Marking bugs for the Firefox 57 release

From MozillaWiki
Jump to: navigation, search

The bug that will overshadow all the hard work we put into the Firefox 57 release has probably already been filed. We need to find it and fix it.

If you think a bug might affect users in the 57 release, please set the correct Firefox versions affected in the bug, and then set the tracking-request flag to request tracking of bug by release management team.

You need the EDITBUGS privilege to do this.

Making decisions as the 57 Beta approaches

As we review the list of bugs, it's important to mark the status flag (affected, not-affected or wontfix). If something is affected, that means we'd consider an uplift into beta; otherwise it's wontfix. You can label bugs as fix-optional for 57, but those will quickly get converted to wontfix. There will be an approximate 2 week window after uplift where we can get non-catastrophic bugs into Beta. After that 2 week window, the bar will be quite high: i.e. "Will this bug trigger a dot release? If not, it's wontfix."
