I've sent you an email. Get back to me for an updated teamviewer password/id
That screenshot is in my first post.
While fiddling I've just noticed I get an error message when I go back from the static preview picture to the live preview.

"Wrong URL"



I can choose a base picture, but thats not what I'm trying to do. Sorry should have been more clear about that. The live preview picture of the site isn't working.
I am trying to use http://www.reddit.com/r/formula1/ and http://www.reddit.com/r/oculus/ but I've also tried with reddit.com and all of them fail.
Thanks for the reply, I'm running on stable Firefox 38.0.5

Since it's working for you I'll see if there's any addons that may cause problems on my end. I guess there is no logs I could check for any hints on what exactly goes wrong?

edit: Tried to turn off all the addons but FDV and I still only get the "Failed" message.
