To fix this I created a new about:blank style, Arctic Firefox, that is lighter while still maintaining the firefox logo goodness.
To install this you will first need to:
- Install Stylish, a plugin for Firefox. Stylish allows you to apply custom styles to web pages, or as they say “easy management of user styles.”
- Go to the Arctic Firefox page and click the ‘Load into Stylish’ button
- Click Save in the window that pops up and you’re done
