They got rid of everything. Relay and VPN are both five years old. Other than MDN, everything they've done, including "browsers and browser accessories" have been killed. For company as old as Mozilla, if your two oldest offerings are less than a quarter of your lifespan, what does that say?
And on the browser front, they're really not making a whole lot of anything. Ignoring fixes and web standards work, the latest version has.... Vertical tabs? Which there's been an extension for since pretty much forever. Some AI stuff? Changing the background of the New Tab page? I'm supposed to be excited for this? This is supposed to make me want to give them money?
Meanwhile there are startups like The Browser Company who are actually doing exciting things with the web (that people use! that are exciting enough to raise funding for!), and users love it. You can't say "we're building the best browser" and then not even ship anything.
What gets people excited are quality of life improvements, like video chat picture in picture, or new ways of grouping and managing tabs (your reminder that Mozilla killed Tab Candy). Firefox only got a cookie cutter clone of Chrome tab groups on v137.
There is no shortage of ways browser vendors can ship features that make browsing the web better without getting in anyone's way. Hell, they could have a build of Firefox that just has all the new stuff and merge it back to trunk when it's been proven out.
The thing is, for people like my mom, every other browser has features she uses and likes. Firefox hardly does more in the core experience than it did fifteen years ago when they started shipping every six weeks. My mom has every single department store's app installed on her phone, she's not choosing a browser based on how much it may respect your privacy.
