(Firefox :: Toolbars and Customization, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.9) Gecko/2009050519 Iceweasel/3.0.6 (Debian-3.0.6-1)

is unconpfortable because of links move away under your mouse-pointer

Reproducible: Always

Steps to Reproduce:
1. open several tabs with content
2. focus one 
3. press f11 to make it fullscreen
4. try to hit a link inside of the screen
Actual Results:  
the screen pans away while fluently hiding the tab-bar after a while

Expected Results:  
content shouldn't move 

the content of the tab-bar should rather "shadow" the upper two collumns of the web-site than pushing / moving around the whole site while re-rendering it for fading in/out the tab / iconbar again and again.
its pain in the ass on netbooks with low cpu and less screen real estate, so scrollbars will appear disappear and make the content jump arround under your mouse cursor.

When in full-screen-mode the client area should be the primary focus rather then the menu/tab handling.

You can disable the animation by setting browser.fullscreen.animateUp to 0 in about:config (the animation was implemented in bug 240859).

Given that I didn't find duplicates, it doesn't seem to affect many users. And because there's a preference for the few who don't like it, it's probably a WONTFIX.

setting it to 0 makes it a lot better, but it still has to change scrollbars (which if the right scrollbar wasn't needed before might also create a vertical one...) A behaviour similar to the windows taskbar when in "always on top + autohide" - mode would be what i'd like here, as still the whole content bounces over the screen.

Reporter, are you still seeing this issue with Firefox 3.6.13 or later in safe mode or a fresh profile? If not, please close. These links can help you in your testing.

downloaded the fresh firefox, created a new unix user, ran the fresh firefox in that user, pressed f11 to enter fullscreen mode, moved mouse up so it would unfold the tab-bar, and the tab bar still doesn't overlay the existing window.

The tab-bar still takes away size of the content-window, resizing the content window with all its consequences.
for example 'www.heise.de' shows it resizing the scroll-bar.

seame behaviour in ff4 beta.

bug 470534 is the most reasonable way of fixing this issue.
