Halp me! D:

Alright, when I run Firefox there's this little box that randomly pops up. Doesn't pop up when I'm running Chrome or any other browser. Here's a picture too:

 

i would uninstall visual studio.

Or look through your addons in firefox, it might have something to do with them.

 

Turn off debugging mode for Mozilla Firefox in Visual Studio.

 

Thanks, trying it now. Hopefully it works :]
