For what it's worth, I gave up on all external bookmark tools and went back to using Firefox's built-in bookmark manager. I enjoy that it's a CTRL+B away to see all my bookmarks, and that I'm able to sync it with my Firefox account.
With a s* for brains search. It fails to search anything, even it's own folders! or parts of the url. or the tags that gets added and removed from the UI every now and then and are ignored in search. heck there's a 18yr old bug about performance being so bad in this search that if you have over 1k bookmarks it will just hang for several seconds. edit: that said, i also use firefox bookmarks exclusively, but just for…
* If I have over 1k bookmarks, that probably means it's time to go in for spring cleaning and start deleting some
* Other comments have made it apparent that you can tag bookmarks, but I personally just prepend the names of bookmarks like "javascript js - How to reverse a singly linked list GeekForGeeks" to make it easier for me to search for it in the future.
In the end, I prefer the benefit of not having an extra site/tool like Instapaper/Pocket/Shiori to have to deal with.
