Chrome does everything you need because Chrome is your baseline that you are used to and because of that your requirement is "it does what Chrome does".
Firefox has features that people "need" but they only know they want it because they already use it and they won't switch away from Firefox unless whatever they'd switch to has the same feature.
Ex: I will never switch away to another browser unless it has extensions that allow you to group tabs and "store them in the background" like you can with Firefox's Simple Tab Groups. Likewise I know people who won't switch to a manifest v3 browser because they don't want their adblock crippled.
TLDR: Your requirements are "whatever I currently use but better". You will never win users by trying to beat a better funded and better staffed project at that. Instead you have to try to do new things and discover what can make your project stand out.
I used Opera before FF due to its unique and innovative features, then FF when Opera became Chinese, then Chrome when FF went to shit by changing its UI for the worst every week.
None of the new features FF introduced did I ever need, and judging by its market share I am not alone. FF just focuses on useless features that nobody asked for. If you asked for those feature, congrats, you're part of the 0,001% userbase, too bad that's irrelevant. Bad leadership. You can defend FF all you want but the market share speaks for itself.
They had unlimited money from Google and they squandered it. That's like playing a game with cheat codes and coming in last every time. Mozilla leadership should resign and go flip burghers at McDs instead as they're shit at their tech jobs.
Mozilla had to just not fuck with the UI, features and put ads, and it would have been as easy win.
