Reproducible on: * Nightly 42.0a1 (2015-07-07) * Aurora 41.0a2 (2015-07-07) * Beta 40.0b2 (20150706172413) Affected platforms: * Microsoft Surface Pro 2 - Windows 10 Pro x64 (Insider Preview Build 10162) Steps to reproduce: 1. Enable "Table Mode" in Windows 10. 2. Launch Firefox. 3. Visit https://www.mozilla.org/ 4. Tap the lock icon and then tap "More information". Expected result: The site information is displayed in a small dialog box or its content is properly adjusting to full screen. Actual result: The site information dialog box is displayed in full screen but its content is not adapting properly to it and the rest of the screen is filled with black. Additional notes: * Intermittently, the content from the dialog is not displayed properly in full screen.

I ended up with the fully painted dialog across the entire screen. I think what you ran into might be a simple drawing glitch. The dialogs you can open off page info though seem to be a problem, I close one and I lost the browser window. That's filed under another bug I think.

Yeah, the interaction of tablet mode with closing windows is not intuitive. I'll look at this as soon as I get done with the titlebar coloring stuff.
