My use case is probably a bit more niche but I have Memory Impairment and bookmarks don't work that well for me. I'm a very organised person and did previously use things like bookmarks extensively. But since my memory has gotten really bad I need more visual representations. Visual bookmarks could kinda work for this but I am yet to find something that's private, easy to set up (or just works out of the box) and isn't fiddly to use. Bookmarks that aren't visual, don't stay in my memory so I forget about them. Search bar helps a bit but sometimes I also can't think of the right words to use to get Firefox to bring up the right bookmark (even with extensive keywords - because I also can't always think of the right keywords to set).

So I have heap of tabs open. I need things to stay in my recent memory and recent use, otherwise they just get forgotten. It does mean over time more and more tabs get left open. But I do fairly regular sort throughs where I go through each tab to make sure it's something unimportant where I've just forgotten to close the tab or something I am actually using/working on.

It's not ideal but it's the only thing that works for me right now. I have so many things going on at once, it sucks that I have to remember so much at once when I have memory issues but such is life when disabled folks aren't properly supported, lack of volunteers means I have to take more volunteer work that I should, western society sucks for supporting parents, and sexism means that I'm still default parent (mother) despite my husband being more progressive than most hsubands/dads are (he's also woefully disorganised which is in part just him and also in part how boys and men are socialised). Anyway, this isn't meant as a commentary on the differences in organisations levels and how that affects tab usage between mothers and fathers lol.
