Seem like mediafire.com block links from adf.ly.
I will solve this problem but currently can use these tricks to open mediafire link from adf.ly.
First Trick
1. Open adf.ly link and wait 5 seconds until show "SKIP AD"
2. Drag "SKIP ADS" to address bar (Just like in this picture)
Second Trick
1. Open adf.ly link and wait 5 seconds until show "SKIP AD"
2. Left click on "SKIP AD", select "Copy link location" and paste it in Address Bar.
