In a tailspin
I remember that Mozilla's Firefox browser was once the only mainstream one that was usable. Once they got to the top of the heap there, they systematically began taking a hatchet to that software, making it objectively worse with every release and update. They gave in to bloat for no reason, in the form of things like "Pocket" and "Hello", which made no sense to literally anyone outside the involved companies, since they already had a robust extensions architecture for such things, but felt the need to bake them into the core browser so everyone had to load them, rather than just those that wanted those things (i.e. nobody).
Unfortunately, they do not seem to show any signs of correcting course. I remember some rumblings about this new "Great or Dead" design philosophy, which they seem to be implementing on some of their projects, including Firefox to a small degree. Unless they SERIOUSLY prune the bloat and sources of instability (Australis UI overlay among others), the software simply is not stable enough to recommend or use.
We're now in a sad situation where all of the mainstream browsers are terrible in different ways, and nobody but small players are interested in making a program that is just a browser, and that's it. This would be fine normally, since we could just go to alternative browsers, as I have done. Unfortunately, that is complicated to a novice because doing so has been hamstrung by companies and people writing web pages to specific browsers, and use of onerous user agent sniffing behavio[u]r that requires me to lie and say I'm Firefox in order to get some pages to let me in.
