For impatient people (like me) who don't want to wait 5 seconds :D! Also adf.ly has started showing problems with mediafire links, so to get those links to work here are 2 ways to bypass ad.fly. (If you have other methods please share them ^^)
Method 1: Delete the ad.fly extension in front of the link once you click it and press enter. It should bring you directly to the link you want.
Delete the section inside the red rectangleMethod 2: Right click the link and copy the url, then open a new tab and paste it in your browser.
I personally use method 1 the most because I'm too lazy to open new tabs and copy and paste xD Both ways should help you to bypass the annoying adf.ly
