Beta/Release Uplift Approval Request

  • Feature/Bug causing the regression: Bug 1532685
  • User impact if declined: The help button now opens only 1 tab (good! fixes regression from bug 1521040) but opens the generic sumo homepage in the user's locale instead of a topical page (bad!)
  • 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: See comment #0
  • List of other uplifts needed: n/a
  • Risk to taking this patch: Medium
  • Why is the change risky/not risky? (and alternatives if risky): The patch itself is straightforward, but I said that last time... I took the opportunity to clean up a difference between windows/linux and mac, so now these help pages will always open in a new tab instead of a new window.
  • String changes made/needed: nope
