Mozilla Developing Secure Full-Screen Firefox Feature
Mozilla's Robert O'Callahan said that the company is currently working on a full-screen implementation for web apps in Firefox.
However, O'Callahan said that Mozilla is concerned about security issues, for example about the fact that a user will not see the URL of a service in full-screen mode.
The engineer suggested that Mozilla could go different routes to make full-screen scenarios more secure, for example by enabling full-screen modes only through a manual user request and providing a pop-up window.
"We can make sure that when going full-screen, we display a clear message describing how to leave full-screen - like Flash does, but hopefully better, O'Callahan wrote. "Then if a malicious page goes full-screen when the user didn't want to, the user will probably exit full-screen immediately."
More problematic are spoofing attacks that occur when a full-screen window is already opened. However, O'Callahan says that "most spoofing attacks require user input that the browser can detect" in which cases the URL bar could be shown. But even there appear to be issues, as especially games are designed to be in full-screen mode all the time "while receiving the full range of user input."
Mozilla does not have a solution for this problem and is asking security researchers for feedback.

So by Nov then, sweet!

Next thing they'll be making their browsers compatible with triple monitor displays....
Haha. I remember I sent a screenshot to one of my mom's co-workers a few years back and she didn't know how to close it. Hahahahahaha. She said she kept clicking the red X button from the picture for a minute or so. Omg... And I even had the silver theme on... I hope I don't EVER get like this when I'm old. Damn.
Full screen is awesome on my netbook, FYI...
Also, I see this as a bad thing. It sounds like it could be hijacked and then the user would think they were connecting to a site but it could then be spoofed.
+1 on memory hog argument. But 412 MB for seems to high to me, with 9 tabs opened right now FF6 is 296MB here.
also, ctrl+ about 3-4 times, its how i get websites to look good at 1920x1200 (full screen, not f11 full screen)
They couldn't think of this?
That would be great. I just started beta testing 7 a few hours ago, I hope to see improvements.
