Dia-like style for Firefox



I like how Dia looks, but could not stand all of the other things. Especially, I love how Firefox's address bar behave. Zen was a bit too much on the other spectrum (no horizontal tabs).

So decided to customize my existing Firefox for the look of Dia. Tbh, this was done with a lot of help from Claude Code. Not sure how much time we have left before Nova come out, but I thought it would be a good idea to share.

So here we go.
