What could cause Vimeo videos not to play on Firefox?

[airborne]

I've had this issue on Firefox for over a year, Vimeo videos will load and buffer but not play whether embedded in a page or on Vimeo itself. Videos of any other kind or from any other site youtube/dailymotion etc play fine.

With Vimeo videos the video thumbnail will load, video buffers or even loads completely but pressing play does nothing, dragging the video position marker forward also does noting.

Anyone else had something similar happen with Vimeo or know a way to solve this?
Probably an add-on or setting but my similar Firefox setup on my laptop is fine

Try clear the cache in Firefox, this normally fixes video watching issues.

Vimeo might use a flash based player. Firefox by default disables all flash scripts - and for good reason.

You mean the Flash plugin?
Mine is enabled and I don't think Vimeo is flash based.
