Firefox Sidebar and Vertical tabs: try them out in Nightly Firefox Labs 131 – Firefox Nightly News

I tried this last night and I actually really like it. The default theme seems to have changed also and looks much cleaner.

And you can have AI models open in the sidebar. Not only chatgpt but also other open source and free models like huggingface. I thought that was very cool.

I don't know if the general public have even tried any other model than chatgpt. It's fun to play around with others.
