If I'm the only one with this problem you can wontfix this. :) Right now we've got 2 options for making the video bigger, either full screen or ctrl+'ing the window. Full screen doesn't work with 2 monitors because when the monitor loses focus it exits full screen (this might be a linux thing). ctrl+ing the window works to an extent (which is what I do) but after a certain size the vertical bar on the right overlaps part of the video. Can we make the bar on the right collapsible or removable or at a lower z-index? If I'm the only one with the problem I'll just remove the bar with adblock or firebug or whatever - I just wanted to file as I figured making the video larger was a common use case.
Less like WontFix and more like Can'tFix, at least right now. The problem is that Air Mozilla is currently just a Wordpress blog, so the only layout control we have is in a WordPress template. I'm leaving this open and marking it as blocking our tracking bug for issues to consider in the next version.
Now that we have control of the layout we should add this to the list of items for consideration when we review UI design.
I think the right answer to this is to implement a tear-out resizable video window. So I'm going to mark it as a dupe of 975517.
