okyrhoe 2 years ago For the past month I can't play videos on Vimeo.com, either with Firefox or with Internet Explorer. However, I have no problem playing the same videos if they are embedded in another site (blog, Facebook). I tried the uninstall/reinstall Flash as suggested on the Vimeo Help page, and disabled Firefox extensions, without any result. In Firefox I can see the starting image of the video. But there is no video player, ie no start arrow, like (heart), etc. On Internet Explorer, not even the start image of the video comes up, it's just a black rectangle.
