Yeah, that's what I was doing as well: using tabs as a poor man's bookmark management tool, because Firefox on its own doesn't care about you actually using bookmarks to any real degree. I basically never had many of those 400+ tabs actually loaded.
Just in case you might want something different, you might like linkhut for trying to deal with this instead. It's something I've recently started heavily using myself along with the extension linkput making it extremely convenient to bookmark all the things. It's open source, bookmarks can be imported and exported via a single HTML file via the web or through various means on the command line (or other external tools) through its 1:1 Pinboard API. Along with other people using the flagship instance of it, it also turns into a great search tool in general, not only for just your own bookmarks. Also has RSS feeds for any combination of tags and user profiles. It's sick as hell.
@kenney
YES! I CANNOT STRESS ENOUGH HOW IMPORTANT THIS IS!
-D.
@TabascoEye @kenney RDR2 does a great job recapping the story thanks to its journal, but the controls… nothing.
I like how in every Ubisoft title there’s always a button to show the current context-aware controls.
@kenney That's a neat idea. Micro-tutorial, as it were.
Not about controls, of course, but a design decision I think is brilliant in Return to Monkey Island is the "Previous on..." feature where if you haven't gone back to it in a while Guybrush gives you a previously-on to remind you of the story so far and what you were up to.
@kenney we could bring back the "help" function of the F1 key.
Or not. Within a genre controls are quite often the same across many games. And controls in the settings menu tell the bulk of the deal pretty quickly.
Probably the only major outliers are simulators. But *their* control schemes can be so elaborate so as to be difficult to forget 
And to the story so far, please.
@kenney Dos shareware games used to give a few screens on how to play, accessed by pressing F1. All disappeared in favor of slower onboarding sequences which appear once.
Doom even did it single screen.
@kenney Elite Dangerous is a game I drop in and out of every now and then (months in between sometimes) and it's very complex in terms of what you, the ship, your ground vehicle etc. can do *plus* all the controls and interfaces you use to do all those different actions.
Luckily, it does have a load of tutorial missions and encyclopedia entries available at all times... so besides constantly having to go through the control settings again and again, I have occasionally done some basic training missions to relearn how to maneuver during dogfights or use mining equipment or whatever.
