Enabling optional features

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.

Development

If you wanna mess around the styles and change something, you might find these things useful.

To use the Inspector to debug the UI, open the developer tools (F12) on any page, go to options, check both of those:

• Enable browser chrome and add-on debugging toolboxes
• Enable remote debugging

Now you can close those tools and press Ctrl+Alt+Shift+I to Inspect the browser UI.
