How to completely remove Folx on Mac OS X? I installed Folx download manager on my MacBook Pro. I didn't like it, so I removed it from the Applications folder. I also searched for its dependent files in /Library/Preferences, but I found nothing related to Folx. 

Now, when I try to download files, it tries to download using Folx—but Folx doesn't work. How can I fix this problem?
For prior version than Folx 4

Go Download the Folx.dmg from their website, and open it. In the dmg image, there will be a package file called uninstaller. Run that.

It is only for prior versions than Folx 4, as said by Eltima Software. For Folx 4 or newer, it is mentionned on their website that it is enough to remove Folx.app to permanently remove it.
