629944 - Full Screen Mode: Duplicated Full Screen Buttons

Status: RESOLVED WORKSFORME

(Firefox :: Toolbars and Customization, defect)

Description

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b11pre) Gecko/20110129 Firefox/4.0b11pre
Build Identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b11pre) Gecko/20110129 Firefox/4.0b11pre

I have one full screen mode button in my navigation bar. When I click it (or use the keyboard shortcut), a second identical full screen button shows up right after the url bar. It goes away when I leave full screen mode, and both buttons are completely functional.

Reproducible: Always

Steps to Reproduce:
1. Make sure the full screen button is in the navigation toolbar.
2. Click it, or hit F11.
3. Notice the second full screen button, and click either one.
Actual Results:  
A second full screen button appeared immediately to the right of my URL bar.

Expected Results:  
There should be only one full screen button at a time. If there is no full screen button in the toolbar when it is triggered, the full screen button should appear after the URL bar, just not when there is already a full screen button on the toolbar.

This problem occurs in Firefox 3.6.13, 3.0b10, and 4.0b11pre (up to date since January 29, 2011).

I doubt this is an issue with addons, but I can try again in safe mode if it would help. I can also offer screenshots, but I feel I already made my problem pretty obvious.

I don't see this in the most recent nightly (Mac OS X 10.6.6) and I don't see this in my own trunk build either (2 weeks old). I added a full screen button to the top toolbar, then went into full screen mode and I can only see one button in the toolbar.

Can you try in safe mode?

You mean Cmd+Shift+F here, I guess? Or are you using windows/linux?

Hm, don't have this problem if I add the button to the toolbar in safe mode (4.0b10). I might try this again out of safe mode with extensions disabled or default toolbars.

Yeah, command-shift-F works too, but so does F11. I'm on a Mac.

Hm, I just reset my toolbars and my problem is gone after I re-added the button. I'll set my toolbar back to what I'm used to and see if it's gonna act up or not.

No issue in Minefield, I'll set this to resolved for now.

Re-resoving as wfm, since the fixed resolution is reserved for bugs fixed with known patches.
