I have installed the fantastic Allvideos 2.4 plugin on my joomla 1.0.12 site (www.bethanybaptist.co.uk) to play sermon files and music videos streamed from youtube.

On the Audio Recordings page i have a table of mp3 audio files with the allvideos player on each line so users can play each file easily on the main page.
Recently i have noticed that in IE the audio plays fine but in Firefox when i click the play button nothing happens - however if i click my mouse on the volume part of the flash player the audio starts playing, if i take my finger off the mouse button it stops and so on.

Could this have anything to do with Joomla mambot/plugin site ordering?
I used to have mgmediabot installed but removed this as i had read about incompatabilities.
I have also gone into the mambot and saved it as read from other posts.

I do not have a lot of Joomla/coding experience and this is my first website so any help would be very much appreciated.

Regards in advance
Justin
