It does behave strangely. I get a long bar where the marker is at 10. If I drag it back to 5 and then click the play button, the second half plays but the video is very tiny and behind the bar. If I try to drag the marker back further, it doesn't play at all.

I don't know enough about WebM to know why this file is behaving weirdly.

This is a 2MB file often used in demonstrations of WebM video. Assuming your bandwidth permits, does this one play normally for you?

It is a 9 second file in other players, so I'm not sure why Firefox shows 10 seconds

VLC shows this when I open the URL.

The file plays if I disable WebM temporarily (media.webm.enabled = false)

Yes, that other file plays fine. Seems like its an issue not just with my installation at least. Wonder if the file is the issue or firefox is.

It is likely that Firefox has a problem with this specific WebM file and it may have to be recoded.
