There is recent issue with Adobe Flash that could be at fault here. Please see Flash 11.3 doesn't load video in Firefox . Let us know if this fixes the issue.

It works now! I can see videos on Firefox. Thanks so much!

Yes same here, after pulling my hair out!.. finally found that yet another update just wasn't worth the energy and time spent updating.

Uninstalled V11 Flash.. installed V10 ... Voila... all back to 'NORMAL' again.. and peace browsing my favourite recipes and videos

NOT impressed with FLASH efficiency -- Thank you Firefox .. now I am not going to Chrome as much (but Chrome is less troublesome).

OMG, i thought i would never be able to enjoy my firefox again, thank you so much, the adobe unistall stuff totally work and it was so easy

I am glad I could help Omar.. but what I don't know is the answer to this question:

When can we know to trust updates? I guess it's the old Xfile's 'Trust no-one' lol

Updating Real Player solved my solution. THANKS LOADS!!
