But worse is, it relies on recalling the text in the bookmark's title to resurface it. You might not remember the page title, but you can always scan through open tabs.
I can also open all in tabs, if I really want to.
Mostly the way I deal with this now is sharing the tab to another Firefox on a different computer then use it there and decide it's fate.
Both of these make context switching easier as I can quickly hide all of the tabs I'm not currently using, knowing they'll be just as easy to reopen later. In Chrome, tab groups can be saved too, so they give you a bit of the persistence of bookmarks.
I'm still a Firefox user where I have a choice, and I'm really excited to hear they're working on first-class tab groups
Example: Have a primary window with you email, calendar and important sites pinned.
Then open another window and open a few tabs.
Then at the end of the day, close your primary window first, then discover you still have the secondary window open and close it as well.
When you restart Firefox you will get the secondary window and your "primary" window will be lost with all your pinned tabs.
I actually went down a rabbit hole of trying to log it as a bug, but the behavior is by design apparently.
