Both Chrome and Firefox show warnings when a page uses the fullsrceen API. Is there a browser out there that doesn't?

The latest version of Safari shows no warning on fullscreen, making users very vulnerable. The only indication is a short, half-second animation (it's much shorter than the usual OS X fullscreen animation). After that, there's no indication that you're in fullscreen mode.

Safari also completely disallows keyboard input in fullscreen mode, which majorly mitigates the vulnerability.

I am not sure why this is on Github? Typically, I applaud when anything is shared on Github. But why this? What positive value is it to anyone other then script kiddies?

(Certainly, most any adequate web developer with nefarious intensions would be able to reproduce this quite easily. But why make it point-and-click easy for them?)

The user can hover their mouse over the link and their status bar will show https://www.bankofamerica.com, as expected. Google search results use a similar technique to show you the "right" link when you hover. (It's only when you click the link does it muck around with the DOM to insert the google.com/... redirect link.)

This is pissing me off. The link hover should be sacred, browsers shouldn't allow any trickery there.

I won't be surprised if both Google and MS restrict this in their browsers in the near future, but make exceptions for their own search engines.

On linux it tries to emulate Ubuntu with default settings, while I have Cinnamon and different theme and fonts, different user name. Didn't terrify me.

But then, people with custom WMs and whatnot (I'm using herbstluft WM and Zukitwo) aren't exactly the target market are they.
