With Bug 1670480 there is a concern that this will trigger an unexpected change for users who are in the following configuration:

  • use the DevTools light theme by default
  • use a dark theme for their system/firefox

When they update to a version with Bug 1670480, their DevTools UI will switch from light to dark.

This bug will be about switching back to the previous values for the default preferences temporarily while we figure out a solution to notify impacted users.
