Gen z? Probably not as they’ve mostly know Chrome as having been the best web browser.

Chrome hasn't been "the best browser" in at least a decade. Even at its peak, it was notorious for sucking up system resources like a sponge.

And that was in the interim period when people were flirting with Opera and Safari on non-Mac machines as an alternative to old-school IE. I remember having to lobby my office just to get Chrome whitelisted (and then doing it again for Firefox a few years later) because using anything but IE was considered "insecure".

Now it's mostly won default status because of the Android OS rendering it the default (much like how Edge is the default on Windows and Safari on Mac). Plenty of Millennials/GenZ had to make their way to Firefox the hard(ish) way by knowing it exists and realizing how many gigs of memory Chrome was eating up.

Gen alpha and boomers, no way.

In my experience the number one "I made the jump to " conversion stories has been the end-user experience. Edge cleaned up its act and runs relatively smooth now. Chrome is still a bloat-a-saurous. Firefox has to fight with an increasingly locked-down computer experience. If you're using a school device or a work laptop and it doesn't come pre-installed, you likely won't have rights to download it.

If I had to bet, GenAs are the ones most likely to do a Firefox install simply because they're the ones most likely to still be out there buying their own PCs for recreational use.
