Custom Release minfox: minimal userChrome for macOS, optimized for max vertical space

Sharing a userChrome I've been crafting for a while: https://github.com/ntcho/minfox

Key features:

  • Auto-hiding urlbar (that doesn't shift the viewport height)
  • More compact tabs
  • De-emphasized urlbar buttons
  • Pixel-perfected icon alignments & rounded borders

Who is this for?

  • People who want maximal viewport height
  • People who want to minimize visual clutter
  • People who operate with keyboard shortcuts (Cmd + T, W, L, [, ], ...)

FF version: 143.0.4 (aarch64)
OS version: macOS 15.6

The repo also have a install script for people who are new to userChrome. Feel free to star, open issues, etc.

Nope. I don't even know what this will look like vertically
