The plugin can be made working for newer versions of Firefox in the following way:
- Rename .xpi file to .zip and unpack
- Within the chrome folder extract fullfullscreen.jar (with winzip) so that the included "content" folder replaces the jar file. (The folder "content" has to be there also, not just the files within.) Then delete the jar file.
-In install.rdf adapt the following line: (changing 2 to 5)
-Next to install.rdf add a new file chrome.manifest with the following two lines:
content fullfullscreen chrome/content/
overlay chrome://browser/content/browser.xul chrome://fullfullscreen/content/fullfullscreen.xul
- Zip up everything and rename to .xpi. Install.

Good luck.

Additional options Rated 5 out of 5 stars

Usefull settings:
1. Buttons on statusbar and Navbar to pin bars (stop hiding) in fuller screen. (Very important becouse of annoing jumping of page when showing the bars)
2. Full screen on FireFox startup.

Works great except that it uses both screen and projection media types; only projection should be enabled. See http://test.dragonzreef.com/mediaTest2.htm

Needs updating to work with the latest Firefox.

Sometimes corrupts the screen when switching to full screen.

Esc to exit Rated 4 out of 5 stars

Would it be too complicate to add the option to use the Esc key to exit?

Does what it should Rated 4 out of 5 stars

I got this addon to be able to hide the navigation bar as well as the status bar in full screen view without completely losing them. Unhiding the navigation bar by touching the top border is intuitive, so is showing the status bar on activity like displaying a link's location. I shortened the hiding delay to 1500ms as that's sufficient to my need (4000ms is a tad too long for my taste).

What's unfortunate is that it doesn't play well with the Tree Style Tab addon which I use on my widescreen netbook, the area of the Tree Style Tab (which I put to the right) is not hidden, but the containing tabs disappear nevertheless resulting in a huge gray unused field.

I have found a way for Linux Fluxbox users to get Firefox in a windowed Fullerscreen. I mean a normal Firefox window that looks like it is in fullscreen using Fullerscreen.

Open your ~/.fluxbox/keys file and add the two lines.
OnWindow Mod4 Mouse1 :Fullscreen
OnWindow Mod4 Mouse3 :MacroCmd {Fullscreen} {ToggleDecor} {MaximizeWindow}

Go to the Firefox menu and select “Reload Config” or just restart Fluxbox.

How it works
In Firefox, press F11 to go into fullscreen. Hold down the “Windows key” and left click anywhere on the Firefox window. You will now have Firefox looking like it is in Fullerscreen but will be able to resize and view other windows.

If you wanted the Titlebar to disappear as well, hold down windows key and press right click when in fullscreen.

If you pressed Win+left click
Just press F11 and Firefox will go back to normal.
If you pressed Win+right click
press F11. Then do Win+right click(you might need to right click twice)
This will give you back the title bar.

There is a slight problem with the tab bar. It might disappear. I get this problem using Tab Mix Plus with multiple tab rows. To get the tab bar back, exit fullscreen mode.

If your multiple tab row becomes just 1 row, you will need to resize the window to correct.

This extension is great, but I cant select what extra toolbars I want to view. The preferences has nothing for it(using Ubuntu 8.10).

linux Rated 3 out of 5 stars

In firefox 3.0.5 (original download from mozilla) for linux, after entering in full screen, one second later the window scrolls down a few pixels and show a few pixels of the upper menu. This can avoided by deselecting the "Hide toolbars" firefox option (unfortunately, enabled by default, I think). This is a bit annoying in order to create a web site easily usable in true full screen mode by novice users.

Yet, the way the original FF full screen should work.

Thank you very much for this extension. A must for small netbooks

It works!
Thank you for fixing it. This is great for full-fullscreen viewing.

Could you possibly add a feature to make Firefox pseudo-fullscreen. What I mean by this is for Firefox to act like it is in fullscreen mode, but is actually windowed. This would help save space on the desktop.

Plus on linux, it would be possible to hide even the titlebar and the taskbar.

I don't really like that I can't switch between apps and keep Firefox nice and clean.

Rated 5 out of 5 stars

Really nice. Though it's missing an icon for placing on the Toolbar so I can click the mode on.

We'd love to have Mac support please! (doesn't work on Mac version of Firefox at present)
