Since currently Lemmy is mostly made up of nerds, I'd like to know what browsers you use and why? You could just upvote the comment with your browser of choice if you don't want to explain.
For Firefox I'm moreso concerned about performance issues that I've run into with certain sites, as well as apprehension surrounding Mozilla (though Google is DEFINITELY not any better). Extension syncing (and general setting syncing, for that matter) mostly comes into play when I try to use something like LibreWolf or Ungoogled Chromium. I love the latter, but it's painful to have to manually sync my extension changes across devices. At least I can do bookmarks with xBrowserSync, but I'm SoL for everything else. 😭
