Mozilla will show off their marketplace for web apps at Mobile World Congress 2012. Mozilla Marketplace will support the upcoming Boot to Gecko (B2G) operating system for mobile devices such as smartphones and tablets. It is rumored that they will announce LG as a partner to develop either a tablet or a phone for developers of the B2G platform.

I ~ <3 Paypal… I guess.

Mozilla Marketplace will be a store where developers can distribute and sell their applications based upon HTML 5, Javascript, and CSS. The marketplace will support both free and paid apps with a variety of terms. Developers can have their users paid for the app up front, within the app for microtransactions, within the app for demo unlock, on a subscription basis (not yet implemented), or by donations.

Paypal has been announced as the payment processor for the Mozilla Marketplace. Paypal is not universally adored although we can understand why Mozilla would need to use an existing package. Prices are locked to one of 30 tiers so pricing is not entirely flexible but does run the gamut from 99-cents to $50 as well as of course free.

Hopefully we will get more details about Boot to Gecko or the Mozilla-powered LG phone at MWC in the coming days.
