Get Firefox 4.
It has some nice new features, in addition to being faster. Some of the addons below require it, also.
A persona specifically for watching movies. It dulls down everything so it's less distracting when watching the movie.
Movable Firefox Button or App Button Clear
That orange button is really distracting! If you choose Movable Firefox Button, you can move the button anywhere, even the tab bar. Or if you like it where it is, the App Button Clear just makes it less noticeable by making it transparent.
Move everything onto the tab bar.
Right click on the Firefox button and click "Organize." Move everything you want onto the tab bar and everything you don't want, delete. This will give you even less distractions. I myself moved up the Firefox Button, the fullscreen button, back and forward, the tab bar (obviously), and the address bar. I can still move around within a site, but I don't have more than I need.
This one lets you hide the tab bar while you're watching the movie. That means that you'll only have one tiny black bar that's required for the minimize/maximize/close buttons! (Hmm...I wonder what will happen if you do all this in GNOME 3...) It's up to you to use either the autohide (which can be annoying if you're trying to browse for a little while) or a quick key press.
Custom Tab Width
If you want to control how big your tabs are, this one will do it, since there's no easy way to resize the address bar.
Smart Bookmarks Bar*
If you still want a few bookmarks on your uber-compact tab bar, this will allow you to make them only favicons. (Don't forget to move the "Bookmark Toolbar" onto the tab bar.)
Make your movie sites a web app....
If you want to, you can open your sites like Netflix, right click on the tab, and click "Pin as App Tab". That way, they're there every time you open Firefox and they barely take up any room.
...or open your movie sites in the sidebar.
Actually pretty handy, you can set your bookmarks to open in the sidebar, so you can continue watching your movie while you browse through the Netflix/Amazon/what-have-you selection.
*(Some of these apps don't technically support Firefox 4, but they still work. In order to make them installable, You have to open up the XPI file with a program like 7-zip, open "install.rdf", change the appropriate line to
That's it! Not alot of changes, but enough to make it worth a post. If anyone else has any suggestions, let me know. Like for example, I thought it would be cool if there was an addon that made the Bookmark Toolbar icons desaturated until you hovered the mouse over them (a feature I saw in bbLean) so they'd be more subtle, but I couldn't find anything like it.
Anyway, feel free to use this as a starting point or leave any suggestions in the comments. Here's what mine looks like both browsing and watching:
