Opening links in Firefox for iOS

This open-source project provides support for opening links in Firefox for iOS. There are classes (for Objective-C and Swift), along with a sample project that uses them, available for reference and use.

Using OpenInFirefoxControllerSwift or OpenInFirefoxControllerObjC to open links

The OpenInFirefoxControllerSwift and OpenInFirefoxControllerObjC classes provide methods that handle the making of custom URI schemes, checking if Firefox is installed on the device and opening the URL in Firefox. We have provided Swift and Objective-C implementations of these classes to accommodate your language of choice.
