Operating system Windows 8 This is happening with Firefox 24.0 and also 28.0. but not with google chrome 34. It was not happening yesterday and apart from updating firefox in case it was my older version nothing else has changed.

I have the same problem :( I am also using Firefox.

I'm also using Firefox and was having this problem earlier this morning. Have you tried clearing browser history? Clearing the cache fixed it for me.

Thank you so very much! It's working again now^^

Thank you I had tried that earlier but it has now worked after a reboot

No problem. Glad it worked for you both. :)

Locking this up as resolved! :D
