I have found Mozilla's sync across devices handy, but now I'm in the process of moving over to using Vanadium on my GrapheneOS phone and FireDragon on desktop.
FireDragon started out as a Librewolf fork, but is more recently based on Floorp. They are still keeping in sync with Librewolf's privacy enhancements, with some of their own thrown in. I like that the default search engine is Garuda's instance of Searx, with Whoogle as another option if you don't want to self host. FireDragon will also sync your Firefox account off Garuda's server instance if you like (which would be more useful if I weren't going with a Chromium fork on mobile). The Garuda project is certainly looking more trustworthy than Mozilla these days.
I caught mumps at around 30, during one outbreak thanks to the proliferation of antivax garbage. Only about half of kids in some London boroughs were fully vaccinated, centered around a couple of the wealthiest areas--and that was nearly 20 years ago. (Meanwhile, I was indeed fully vaccinated as a kid. It's not foolproof, and especially not forever.)
Thankfully recovered just fine without complications, but that really was NOT much fun. Adults are pretty much guaranteed to get sicker, even if they're otherwise fairly young and healthy--and lucky enough to avoid any of the serious complications which are likelier to occur.
