Hello I'm new to the GS4 and everything was working fine until I installed Firefox for Androids. After installing Firefox anytime I am using the twitter app I see a link to Instagram. I had prevously set the instagram app as always ude as defaukt before FF was installed. However, now I can only choose between Firefox and Internet Browser!!! Despite clicking on an Instagram link I am not given the choice to even select Instagram app as default choice. The same holdd true for Keek and Vine links as well. I have the Keek, Vine, and Instagram apps installed and had them all set as always use as default action in the Twitter app. After installing Firefox I am ubable to select any of those three apps in twitter. I am only given the options of picking from Firefox and the default Internet browser. I do not want to uninstall Firefox as so far its the only browser on my GS4 to play Flash. How can I choose from more than just two apps when the "Choose default action" window pops up? If this is not possible how do I remove the Internet app?
