Approval Request Comment
[Feature/Bug causing the regression]: Enterprise Policy Engine
[User impact if declined]: about:preferences will indicate that PDFs will be previewed within Firefox even if that feature is disabled by policy.
[Is this code covered by automated tests?]: The policy has tests to ensure that it is functioning properly. There is not a test to ensure that this particular UI element displays properly.
[Has the fix been verified in Nightly?]: Yes
[Needs manual test from QE? If yes, steps to reproduce]: Abe will be verifying this fix.
[List of other uplifts needed for the feature/fix]: None
[Is the change risky?]: No
[Why is the change risky/not risky?]: Patch only affects whether the PDF handler is enabled in the UI and change has no effect if the policy engine is inactive or if the DisableBuiltinPDFViewer policy is inactive.
[String changes made/needed]: None
