Created attachment 8893459 [details] Screenshot of problem On the pt-BR first run page, text is overlapped. See attachment. font size is at 150% (recommended by msft for my 4k screen). I tried to reproduce on Chrome, but our firstrun page doesn't work on Chrome. We should really do something cool like animate a Firefox logo rising instead of the sun on Chrome :)
Thanks for the report - this looks like a dupe of Bug 1387034, which there's already a fix in for.
