A while back I spent a few weeks figuring out how to configure Firefox to work exactly how I want a browser to work, then months happily using it. Then a big update was released and everything broke. I never bothered to get it working again. And despite claims of performance improvements that came with the release, it still chugged slower than Chrome. I would love to use a browser that I can actually configure how I want without things breaking every week, even if it's slower in general. But if I can't configure reliably and it's slower -- what's the point?
Actually there is a fairly secret long term version of windows 10 that also does without all the bullshit. No store, no constant massive feature updates, etc. Windows 10 LTSB / LTSC. They try to make it seem like its only for embedded machines but its basically just stripped down windows 10 with a lot more similarities (feature wise) to what windows 7 was.
RedHat has no magic Mozilla sauce, they simply ship Firefox ESR and upgrade it every year. You'll have the same breakage in the end, just yearly instead of monthly.
