Even if you had a system that could ... the average mind isn't able to process and remember that many items of data ... there's a reason why they came up with seven digit phone numbers decades ago ... most people are capable of recalling on average about seven numbers in a sequence ... anything beyond that takes more training ... anything beyond about a hundred things takes years of memory training ... and anything beyond a thousand things is a one a million freak ability combined with training.
This is why I have about 5k tabs arranged in containers and groups. If I change between topics I hotkey to bring up the grouping panels. Stuff for network management can be left to return to exactly where I left off. Same with the web control panels for my 3d printers. Isolated social media crap, work crap, etc also.
With all the web apps and documentation and references, it's just too much of a pain in the ass to dig up a bookmark only for it to be a forgotten number of pages/scrolls/dynamic bullshit behind. Its like a modern version of losing my position in a school textbook. I'm old and battered enough now that merely being alive is a chore and nobody can tell me to close my tabs.
Years ago I wiped a friends IE history with CCleaner.
She freaked out because it turned out she wasn't saving barely any favorites/bookmarks and was relying on the browser's history to "save" her visited websites.
Firefox handles those poorly heads up. If I search "random topic" and all my related bookmarks populate I cannot open multiples. I cant select multiples to move. Their app sucks.
I often go through a late night browsing session and open up three or four Firefox windows with ten to 12 tabs in each .... but after about an hour it all just becomes too confusing and distracting. So I got in the habit of just nuking everything every hour or so. Just shutdown all of firefox and restart again.
If I found anything significant, then it was bookmarked, noted, turned into a PDF or documented some other way.
Stuff that had a bit of importance go into bookmarks, more important info is noted with the link, stuff that is very important is fully documented, linked and turned into pdf. Everything else is just forgotten because they weren't that important.
So, a normal user, lol. I may reach 50ish during my "late night browsing" but close them once I'm done. I've fallen into the same 5 websites for everything habit.
While this might seem like a horror story for those who value their browsing tabs and history (and for systems with Chrome browsers), Hazel retrieved those tabs-of-treasure thanks to the X community explaining how to restore an old Firefox browsing session from the profiles cache.
Good news for her. But I must say that's not a healthy way to use a web browser. Even on my phone at about 50 Firefox tabs I will clear them all. If I was that crazy I would have 10 backup copies of the profiles cache file so I'd never lose it.
There are extensions for this sort of thing... i have probably 40 or 50 tabs stored in groups, but i use a tab group extension to allow me to store tabs based on context, and switch between them easily. Ive got my normal tabs, my shopping tabs, tabs for learning stuff for blender, programming tabs, all grouped off so i normally only ever have 10ish tabs open at a time.
