Wow. According to the vote you guys like Firefox. Want your Firefox to look cleaner and sleeker? There is so much you can tweak. If you haven’t optimized your Firefox setup so you can do more efficient research/development/browsing/downloading, it is time to start. Stay tuned for more posts that will look at different ways to improve your ‘fox experience.
Today we will look at modifying the userChrome.css file to remove unused menus, give you more viewing space, and generally give you the flexibility to see only what you care about and nothing that you don’t. Mozilla has created a Configuration Guide that you should check out to find the directory to create your userChrome.css file (it does not exist by default, but there is an example file in that folder).
Find it and open it up in your favorite text editor. Paste any of the following snippets under the @namespace… line at the top. Make your edits and restart Firefox to see your changes.
