Humble Bundle has worked out a partnership with Mozilla to offer a new package of browser games - the Humble Mozilla Bundle - which can be purchased by gamers at a fairly low cost in support of some well-known charities.

With Mozilla having recently announced that devices running its Firefox OS will start shipping to consumers in the next couple of months, popular microblogging site Twitter has committed to a Twitter for Firefox OS app for the devices.

At its Sunday press conference at the 2013 Mobile World Congress (MWC) event in Barcelona, Spain, Mozilla - the not-for-profit organisation behind the Firefox web browser - announced that it will be launching mobile handsets running its own mobile-devices OS, the Firefox OS.

Mozilla has recently announced the release of its newest Firefox beta for mobile and desktop, bringing aboard the browser a number of attractive features, including support for Retina Display for OS X version 10.7 and higher, along with preliminary support for WebRTC.

Just days after rolling out Firefox 12 with a number of enhancements, Mozilla made a beta version of Firefox 13 available online.

Firefox 13 promises to offer easier and faster Web navigation, thanks to the default incorporation of SPDY- the successor to HTTP. SPDY hacks the amount of time it consumes to load a website and makes browsing more secure.

The software maker wrote in a blog post, “SPDY encrypts all communication with SSL, which makes browsing more secure. Users will notice quicker page load speeds on sites that support SPDY networking.”
