YouTube videos & some other video sites will not run in V5 + V6 yet they do so in Safari and IE.
In FF6 & 5, when running many video clips especially YouTube I can view everything including the "run triangle button". On clicking that button I receive the error message "an error occurred, please try again later" yet, at the bottom of the YouTube screen I can view additional images for other movies. However, to click those images results in the same message.
I have checked cookies and can't find any saying I have blocked YouTube cookies. These same movies run as required in IE & Safari. FF is not crashing and only produces the error message within the YouTube or other video window. Not, some other varieties of videos run as expected within FF6
As a long time Mozilla groupie from way back to the days of Netscape 1 I find this most disconcerting. Help please!
