Open `userChrome.css` with a text editor and follow instructions to enable extra features. Keep in mind this file might change in future versions and your configuration will be lost. You can copy the @imports you want to enable to a new file named `customChrome` directly in your `chrome` directory if you want it to survive updates. Remember all @imports must be at the top of the file, before other statements.
## Known bugs
### CSD have sharp corners
See upstream [bug](https://bugzilla.mozilla.org/show_bug.cgi?id=1408360).
### Icons color broken
Icons might appear black where they should be white on some systems. I have no idea why, but you can adjust them in the `theme/colors/light.css` or `theme/colors/dark.css` files, look for `--gnome-icons-hack-filter` var and play with css filters.
