Beta/Release Uplift Approval Request

• Is this code covered by automated tests?: No
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: Yes
• If yes, steps to reproduce: - check that there's a toolbar with a Download button on the top of the pdf viewer

• open a pdf in Fenix
• tap the button "Download" and the pdf should be saved in the Downloads folder on the device

• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): It's a small change.
  The toolbar itself has been introduced in nightly few days ago with no specific issues and we just changed the css today to make more friendly with the help UI/UX team.
