Thanks to the Light Switch add-on for Firefox, you can hide any other content on the website you are looking for that is not some sort of multimedia. Once you install and start using this extension, you can quickly "turn off the lights" when watching videos or checking out pictures too.
Add Tabs to the Title Bar

Need more space in your Firefox toolbars and menus? If you want to eliminate some dead space in the browser, then you need the Tabs Always in Titlebar add-on for Firefox. This extension for Firefox will bump your tabs up a level – giving yourself a little more minimalistic view of your default Firefox GUI.
Leanfox – Minimal Theme for Apple Fans

Looking for a lean, mean Mac only Firefox theme? If you want Firefox to look a little more minimal on your Apple-powered PC, then look no further than Leanfox. This theme has all the style and substance you need, and little to no distractions in the interface.
Le Breeze
Just like Whitehart, here is another simple theme that anybody could use. Personally I don’t like for the browser to get in the way of the content – so with a theme like that, you have nothing to worry about. It is simple and to the point, and does not distract you with a bunch of wacky colors and flashing lights.
Whitehart
When you want a simple, small and to the point Firefox theme – you want Whitehart. Now from the name it reminds me of some brave knight that would go slay a dragon or two. Well, I guess you could think of this theme as a knight slaying the big bad Internet if you wish. The simple – yet elegant appearance makes this theme perfect for any minimalist out there.
