@ Mads,I'm not sure exactly what your problem is with my post?

Is it the suggestion to use Flash Aid (which is frequently recommended as the first port of call for flash issues within FireFox), or the fact that I started the post by asking the OP whether he had tried it, rather than just telling him to do so? Having recieved an answer that he has tried Flash Aid and it made things worse then I would attempt to help him by other means as it must be a problem with Firefox and his setup. If you feel like '
reporting' me for that post then feel free and let's see what the admins think about it.
@ vinyl_key,Sorry that Flash Aid caused problems - that surprises me. To try and work out what may be causing the problems;-
Is this just on YouTube, or do other flash video sites suffer the same?
Have you tried to view the same videos through the HTML5 portal I listed?
Is the same issue seen if you install another browser, such as Chrome?
Also, what problems did Flash Aid cause? You should be able to remove it from the FireFox add-ons and reinstall the original flash plug-in from Synaptic without any problems.
