Hi, when i try to run mozilla plugin container (on flash videos) in fullscreen mode, it just runs on left screen. I've managed to make it work, but when i have to monitors, it goes fullscreen on the left one, i need it on the right one, i managed to make other aplications, like VLc to work on my right monitor properly, jus making my right monitor the main one (editing monitors.xml on my config directory). But still, it doesn't work on firefox. I'm working on Ubuntu 14.04 on gnome shell enviroment. Thanks!

These are references for ask ubunutu, however you can Reset Firefox to defaults if there are preferences that are not saving. http://askubuntu.com/questions/253907/failed-to-open-and-save-monitior-con... http://www.sudo-juice.com/dual-monitor-settings-in-ubuntu/

This may also be a question beyond this forum. If you cannot find an answer here try the ubuntu forum above or stackoverflow.com :-)

Thanks, but i already have that done, in my case, VLC and other players works in primary monitor, that is the external one, and in xrandr, my external monitor appears as primary one, so that's not the problem, the problem is that mozilla persists in going to the laptop monitor, even if this is not the primary one.

Thanks anyway! ;)
