How to Remove IDM-CC
IDM CC is an extension for the Firefox Web browser that allows it to integrate with the utility Internet Download Manager. Internet Download Manager can make some Web downloads faster by downloading different portions of large files simultaneously from different servers. If you have tried Internet Download Manager and decided to remove it from your computer, IDM CC remains in Firefox because it is a separate program. Remove it from the Firefox Add-ons menu.
Open the "Tools" or "Firefox" menu at the top of the window, and then click "Add-ons."
Select the "Extensions" tab to see the list of your installed Firefox extensions.
Select "Remove" under "IDM CC." This removes the IDM CC extension from Firefox and prompts you to restart the browser to complete the removal process.
Click "Restart Now" to restart Firefox with IDM CC removed.
