I am getting them on openbsd, I assumed it was going to be some sort of certificate issue, I was going to update, but with these recent reports of Mozilla getting ready to turn full bore into a ad company, I might just wait until after March 14th and see what happens.
What is especially funny/insulting, is there is a click here to update button, and I am like "there is approximately a 0% chance that will actually work on openbsd".
Which version of each are you running? I use esr these days (I don't remember why I switched though).
