For those who don’t know, Mozilla announced a few days back that it will be releasing a new browser for developers ‘soon’. While it’s not a new browser but its a new version of Firefox Aurora that has been redesigned and launched as Firefox Developer Edition version 35. Mozilla has always had pre-release Alpha and Beta channels that allowed developers to download the upcoming versions of Firefox to test their add-ons and websites. Now, it appears that, the alpha / Aurora version has been rebranded as Firefox Developer Edition.
