Experimental feature but can be enabled in firefox stable in Settings, Firefox Labs, Tab notes under Productivity.

I found it really useful for when Im researching something and have lots of papers open in separate tabs. Though Im using it more like tab tags, since notes show up when you hover over tabs. It lets me see at a glance which specific topic a tab is related to if I forget.

What do you all think? I was kinda surprised how little discussion I have seen on this, considering that no other browser have something like it. Firefoxs implementation is pretty smart too, instead of just being a sticky notes widget in the browser (like the one in Vivaldi).

This is great, same for me, webpage title doesn't always help and I'll often have loads of tabs open for teaching resources as well as research (am HS teacher)

This was already a thing with a now unsuported first party Firefox add-on.

Yeah I haven’t seen much innovation in the browser space lately (Zen was a nice try but I hate the way it handles multiple windows/multiple monitors) but most features that get added into mainline browsers were once plugins

Notefox by Saverio Morelli: "Take notes on every website in a smart and simple way!" Recommended by Mozilla. Available on Android.

A real innovation would be to pick up the pieces left by the independent developer who ported the Gecko engine (with add-on support) to iOS and start lobbying regulators to mandate its inclusion on the Apple Store. Versus their current, anti-antitrust lobbying.
