Saw some comments about people not being able to use this add on with the latest Firefox alpha code, guess there are a few people checking out webm and the vp8 codec :-)
I 'tweaked' it and got it to work.......
Attached a sample modified .xpi file , all I have done is changed the install.rdf xml as follows :-
em:maxVersion3.7a5</em:maxVersion>
