Back in mid-2010, Mozilla released Firefox Home, an iOS app designed to sync users' Firefox histories, bookmarks, and open tabs from their desktops to their iOS devices. Several months later, Mozilla acknowledged that it had no plans to bring a full-fledged Firefox browser to iOS, due in part to "technical and logistical restrictions" that would make it difficult to create an acceptable user experience on the platform.
While Mozilla apparently still has no desire to try to replicate Firefox on iOS, The Verge reports that Mozilla has been working on a stripped-down browser known as "Junior" that is intended to simplify and improve the browsing experience on iOS.
Junior offers a full-screen experience for users that forgoes tabs and relies on a pair of navigation buttons at the side of the screen to access the browser's functions. Navigation is accomplished through a separate page showing recently-visited pages, bookmarks, and a unified address/search bar. Junior also supports the creation of multiple user accounts, recognizing that the iPad is frequently shared among members of a household.
Mozilla still has a fair amount of work to do on Junior, and thus it will likely not be making a public appearance for some time, but it could add another notable browsing name for iOS users to consider as Google has also been reported to be bringing Chrome to iOS.Update: A Mozilla spokesperson has contacted MacRumors to clarify that Junior is still in the experimental stage and may never see a public release.

, I think third party browsers at a lot of functionality on iOS. You can do things with browsers like Atomic and iCab that you just can't with Safari (changing user agent, "plug-in" like javascript functions, seeing page source, downloading, uploading, lowering the brightness further from the lowest setting (great when in total darkness)).
