Here's a thread of cool things I found exploring the #Firefox Developer Tools!
First, a really convenient thing: You can "pop out" the Toolbox into a separate window!
To do this, open the Toolbox (using F12), click on the ellipsis menu on the right, and select "Separate Window".
I like this much better than the default "docked" modes, especially when using a scrolling window manager like #niri!
