The issue for me with Firefox on Android is it would sometimes refuse to load pages when switching back after being suspended from the background and I have no clue why. I'd have to open a new tab and copy the URL to force it to load and it was so frustrating.
I use Brave now (with the promotional stuff off, even though I still don't fully trust them), since it seems to be the only other ad-blocking browser on Android that's even decently easy to use. However, I still use Firefox on Windows with tree style tabs and raindrop.io to sync bookmarks, both of which are god tier productivity tools.
Loved Boost for Reddit and realized it was the only reason I actually checked reddit for anything. Super excited to use the Lemmy version, especially since it was killed right after the Material 3 redesign lol.
