If you enter the fullscreen mode [F11] you will see a strange white and a grey line on the top of your screen. I prepared a page where you can see nothing but a picture. 800 pixel width, 600 pixel height. It's completly black, but there is a red line on the bottom of the picture, it's 1 pixel in height. The picture starts on the most left and on the most uppest pixel of the screen (or at least it should if firefox would do what the source code tells him to do). So you should see everything black, but the red line on the bottom of your screen if your screen resolution is 800x600. Instead, you see a white and a grey line on the top of the screen but not the red line on the bottom. you can see the red line, if you scroll down with your mouse wheel. No you can't use the scrollbars, they are disabled in the source code, so that they don't waste space and a picture of 800x600 can be displayed if your screen resolution is also 800x600.

Reproducible: Always

Steps to Reproduce:
1. go to http://www.ontheserver.de/temp/Mozilla/Firefox/fullscreen
2. change your screen resolution to 800x600
3. press [F11] to enter the fullscreen mode in firefox
4. don't see the red line at the bottom but the white and grey at the top

Actual Results:  
you see a grey and a white line on the top of the screen.

Expected Results:  
The white and the grey line shouldn't be there. But you should see the red line on the bottom of the screen.

I am using the default theme. Maybe it has something to do with the theme.

Firefox doesn't provide 800x600 pixels in fullscreen mode, only 800x598.

Reporter, do you still see this problem with the latest Firefox 2? If not, can you please close this bug as WORKSFORME. Thanks!

yes, bug still exists in the latest version. Can't you confirm the bug?

I would guess the gray bar at the top is by design.  When I move the mouse pointer over it, the location and tab bars appear.  When I move the pointer away from those, they disappear and the gray bar is left.  I suspect it's to prevent people from being "trapped" in full-screen mode, but I'm just guessing.

Reporter, with the latest Firefox 3 beta, can you confirm that if you move the mouse pointer over the gray bar at the top of the screen when in full-screen mode, the tab bar and location bar appear?

I don't have the version 3 installed. I am still working with 2.x and there is no mouse over effect in this version.

Confirming as an RFE, though since the gray bar is intentional (see bug 240859 comment 5), I'm wondering if this should be a WONTFIX.  CC'ing mconnor to find out.

I don't know what it'd have been in Firefox 2

In Firefox 3, this is the auto-hide bar, but not in Fx2... going to just resolve this as INCOMPLETE since we probably don't have enough information to figure out what the original user was seeing, or it's now INVALID.  Not entirely sure, so INCOMPLETE seems best.
