Firefox copes fine. Me? Not so much (:
Use some kind of tab session manager addon, and start organizing things - no need to have them all open concurrently.
I used to bookmark everything into Diigo. Then their Firefox extension stopped working... and I haven't got a cross-platform, cross-browser process up and running again.
Is there a tab session manager that does that, and lets me send tabs from my current session to another session? E.g. I'm on my "Writing C for a hobby" session and quickly search for something cooking related, and then need to send that to my cooking session?
I use tab session manager on firefox. It doesn't easily let me shift around tabs inside a session, if I want to combine sessions I have to open both and save as a new session. It does allow duplicating and trimming tabs from a session though.
If you need better session management capability, you could probably get an LLM to extend/fork an existing extension to add what you need with about 30 minutes work.
Searchable. Works with sync. Stores the tabs as bookmarks.
EDIT: and recommended so it gets vetted by Mozilla.
