I am developing an web app with HTML5 offline browsing support. I wrote a manifest file as shown below:

CACHE MANIFEST

CACHE:
audio/a.ogg

NETWORK:
*

When I visit my app in Firefox, A warning message prompts saying:

‘This website [192.168.2.14] is asking to store data on your computer for offline use. Allow, Never for this site, Not Now‘.
See https://dl.dropbox.com/u/83574968/ff-offline.png

I am using FF 14.0.1 stable on Ubuntu 12.04 and Chrome works fine. Apparently I can’t control which browser end users use and it seems users tend to disable offline storage on seeing the warning message: see here

So, is there any way to walk around this warning message in FF if I want to use offline storage?

Thanks.
