I often find myself browsing videos on different invidious instances or posts on various lemmy instances, and I would love to be able to create a “watch later” list or a “favorite” list that works across all of them. I don’t want to have to manually import and export these lists between different websites, either.

I’m currently using a single bookmarks folder to keep track of everything, but I don’t like this because it’s a mess. I’d like to be able to create two or three different lists for different groups of websites, so that I can easily find what I’m looking for. For example, a favorite list for reddit, tumblr, etc, another list for invidious instances, and other lists for other sites.

Is there any way to achieve this? I’m open to using browser extensions, third-party apps, or any other solutions that might be out there. I would prefer a free solution, but I’m willing to consider paid options as well.

I use Manjaro Linux and Firefox.
