Comment 5 for bug 1748761

I would suggest that you submit a merge request, where you propose the change be merged into:

https://code.launchpad.net/~mozillateam/firefox/firefox-trunk.head

Then there is a need to make the same change for the snap version, but that seems to be a truly upstream matter:
