Ok so here is the problem that got me looking at this.
Recently Battle.net closed their "website bug forum" for the Diablo 3 forums. In its place the put two buttons at the bottom of the page next to the red Blizzard logo. In linux I have tried Firefox and Chrome but neither show those buttons.
I recently installed virtualbox with Windows 7 lately for a certain program that doesnt run on WINE so I opened up IE. Sure enough the buttons are present in IE. Then I installed Firefox on Windows 7. The buttons appeared there too!
This isnt just one computer either. I have another laptop with the same exact problem.
So, what is the issue? Why is it on Windows that things are working normally but on linux they arent?
