Can you copy the raw data from Help > Troubleshooting information using the button there, and put it in an attachment here? ( https://bugzilla.mozilla.org/attachment.cgi?bugid=1098034&action=enter - you can paste it in as an attachment at this link)

Does this happen on 34 beta? ( https://beta.mozilla.org/ )

Always the same with Vimeo (( 

I see something (strange perhapse): right click reveal that Firefox doesn't see this video as flash content. While videos (from other services/domains) that play normally show in right click conext menu completely different options, that is "About Adobe Flash player" etc.
