Firefox is working on tab groups. However I suggest Firefox implement a slightly better version where the browser suggests to the user to automatically group their tabs when they reach a certain number of opened tabs, say 25. Edge currently has a feature called organize tabs that does something similar, but it's a button, and the action has to be triggered manually. I believe a better implementation would be to have the browser suggest to the user, to automatically organize and group their tabs when they reach a certain number of opened tabs. The user should be able to toggle the feature on and off. I believe edge uses AI for their implementation of organize tabs.
