It may be that I remember associating Limewire specifically with music. I know it was just a torrent client, but as a highschooler I only knew it as a way to get free music. I think a lot of people in my school had the same impression.
Once I was more tech savvy I also went the uTorrent, qbittorrent route. That’s what I use in my Jellyfin setup today.
Raindrop.io. I use the Firefox extension on desktop and the android app. Bookmarks are in the app, not actually in the browser, but it’s simple and it works. It also makes bookmarks easier to search.
