There have been some issues with Firestick users successfully downloading the Mobdro app. This prompted the official Mobdro website to post a step-by-step tutorial that they say all but guarantees success.
Start the process by navigating to the “settings” section on the Amazon Firestick homepage. Once there, find your way to “developer options.” Choose the “apps from unknown sources” option and turn it on. You should see one of those warnings about downloading content from unknown sources; check “okay” anyway.
Navigate back to the homepage and get to the search bar. There you should type in “ES File Explorer.” Users who have previously successfully downloaded Kodi may already have this available.
Once you have selected and downloaded ES File Explorer, select “favorite” from the menu and choose “add.” Next, you should type in the file path http://bit.ly/2oxB1rb and rename it Mobdro. Click “add.”
Click on “more” in the bottom right corner of the screen and choose “open with ES downloader.” This begins the Mobdro download on your Amazon device. Click on “open folder” and install Mobdro. Once it is fully installed, navigate back to the homepage again and go to your apps. You should see Mobdro in the ribbon. Click on the app and launch Mobdro to begin the streaming process.
