A common sentiment (which I share) is that Firefox has less and less to distiguish itself from Chrome(ium). Along with compatibility issues (even if they are rare and not Firefox's fault) there is less and less reason to choose it. Being as good as Chrome is not good enough to maintain users when Google is agressively pushing their browser in ways that Mozilla simply can't.
So why would anyone use Firefox over chrome?
Because it is open source? Sure, but so is Chromium. But both seem to have mostly cathedral-style development and someone outside of Mozilla is unlikely to be able to influence the direction of the project in any meaningful way. It's open source software but not an open source project. User feedback is continuously ignored, often with the only argument being developer convenience.
Because of a focus on privacy? While they do like to push that angle in their marketing and in some ways do more to prevent websites from tracking you they show little concern for making the browser itself respect your privacy with opt out telemetry, eperiments, in-browser advertising and more. Again, any user pushback is summarily dismissed.
The only remaining advantage are some niche features here and there. And those are often provided by extension whose API Mozilla limits more and more.
So I still use Firefox but its only because it is the lesser evil, and the differrence is shrinking. I certainly don't trust Mozilla's autoupdates and won't use upstream builds. Thankfully Linux distros still provide a last defense layer - but that we need that layer at all for something that is supposed to be an open browser is ridiculous. I don't fault anyone who says fuck it and just uses Chrome so that ALL sites work out of the box.
I use firefox on Linux for a pragmatic reason actually: it has a better font rendering than Chrom(ium). On my 4K screen I've started to notice that, with all the fixes for it to work right on Wayland, the fonts are still somewhat blurry. I googled and apparently some experts say that Chrome breaks some font rendering rules, on linux. On Windows I guess it isn't an issue since people wound surely notice.
