As Firefox is by far my most used app, I find that bookmarking the current tab and describing the task with no more than a few words or even as little as a few chars, to be a good way to keep track of what things I need to do soon. For things I would get to later or whenever I feel like it, I’ll put them in Firefox’s “Boookmarks Menu” or “Other Bookmarks” folders, and have lots of folders consisting of Reddit posts and searches about different topics.
OP has 0 downvotes (here on my instance at least) just not a lot of upvotes either.
Also I use them a bit different as shorrcuts for sites I need to visit often so when I have to do stuff for studys or in peivate I can get there very quickly.
to me op has 6 downvotes. maybe look at your settings, i remember after an update i had to turn downvotes back on
edit: (forgot to say it before) i also use them like that, the first ones being things i visit often (but not often enough to remember the link easily), which i leave in specific folders, and the rest is to-do stuff or the same as the other thing but more important
