What

The browser error classifier recognises two additional failure messages instead of leaving them unclassified.

Details
  • A safety-category lookup failure maps to the new category_lookup_error type.
  • The extension being switched off maps to domain_blocked.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
