Any time i hit the 'Preview' button in a new thread or replying to a post, it just shows "Fetching preview..."
If i use the "Quick Reply" at the bottom of a thread and hit 'Preview' it works fine.

Using Ubuntu, Firefox 45.0.2
Plug-ins...
Adblock Plus enabled/disabled dont make difference.
Ghostlery enabled/disabled dont make difference.

Same with Win7 and Firefox (sorry, dont have win7 firefox version)

Is it just me ?

Works fine here (using Win10 and Safari).
