I think a lot comes down to preinstalled SW on phones (Chrome/Safari) and the enterprise world. My rather large employer just switched from FF preinstalled to Edge for all work devices since it alreadz comes with Windows.
Maybe Firefox is missing a really compelling enterprise offering for Desktops? Everybody less savvy is on mobile anyways, which is dominated by the Duopoly Apple/Google.
Actually in my country DuckDuckGo is the only reliable search engine left. Google started giving me a bunch of bogus results for very specific queries a couple of years ago. Sad that FF depends so much on Ma'Google.
Affinity is just great and reasonably compatible with Adobe files. It's been my way out of the Adobe hegemony, after trying for Corel or Opensource tools for years. Without the creative cloud client crashing life has been so much more enjoyable !
