I know that we can use moonlight to play silverlight content on website.
However, I know that moonlight can install on latest firefox. However it does not reliably work actually after i follow their procedure to install it again.
Moonlight extension not working with new Firefox versions
Does anyone able to play silverlight content in Firefox using 11.10?
No, this is impossible. Sorry. :(
Silverlight is proprietary; run by Microsoft, if I'm not mistaken. As for the sites that don't work with Moonlight, well, you're screwed unless you can get Virtualbox to work for you.
Moonlight works with Firefox these days (I'm running 19.0 right now, and it's working,) but, so far, I have never, ever, seen a single thing that supported Moonlight: video, service, anything.
If you've installed Moonlight on your Firefox after updating, but it still appears not to work, I'd recommend contacting the site's feedback centre to let them know how much you'd appreciate Moonlight support.
Is is possible now thanks to the trick shown at the end of this answer:

(uses wine and Firefox for Windows in Ubuntu).
