There aren't too many software sectors that are changing, tweaking, and innovating as fast as the browser sector
. Mozilla's Firefox is fighting for mindshare and marketshare against the likes of Safari, Internet Explorer and Google's Chrome, and given that the true future of the Web is likely on the mobile, it's hardly a surprise to see a lot of new changes coming to Firefox's mobile counterpart.
The beta build of Firefox 25 has been announced, and it's going to be quite an improvement once it hits the masses. The major add is a Guest Browsing mode, which will allow you to hand your smartphone to a friend and let them hit the 'net without fear of them logging in via any of your account passwords. When your guest signs out, your browsing session returns to normal.
There's also a mixed content blocker, support for new add-ons, and an option to set your own pictures as contact photos / wallpapers. Interesting in taking a peek? Download it from Google Play.
