I have an older friend who used Ubuntu on his laptop, as he had never used Windows and just wanted a simple web browsing capable laptop (before the days of Chromebooks)

The number of times I've discovered umpteen copies of Firefox tarballs on his desktop, and every time he complains it's been a pain to 'upgrade Firefox'

Sure, I could have done more handholding, but yes, Firefox could certainly have made it easier back then and still today.
