Same. I stopped using bookmarks around 1999 or so because I found them to be a terrible solution to anything, really (it was a graveyard where links went to die, and this was before bookmark syncing was a thing, so you always forgot to back them up as well).

I've tried all the third-party type attempt to solve it (everything from saving the links in a textfile I always keep open to ReadItLater, OneTab, Pocket etc. All those things are where tabs go to die, never to be read again. More like ReadItNever, amirite?). That's a "solution" I guess.

Now I try to be more selective in what I "keep" to read later, and as soon as I hit 40-50 tabs, I go through and kill a bunch of them. It hurts a bit, but not as bad as when I have hundreds of tabs.
