I have been publishing IDMcc addons on or short after release dates of latest Firefox beta versions - since Firefox 6.
Hope you find it useful. If so, just put a comment and show your appreciation.
Click on the button below to install. Firefox will ask you to install/update Internet Download Manager Firefox add-on version 7.3.17 on your browser (Should I say that you need to allow now ?).
How to Install here is Guide of Installation.
Internet Download Manager is a commercial software and it is NOT included here. Please purchase/try the software from http://internetdownloadmanager.com . I'm not affiliated with them in any way except I'm a huge fan of it. For those who want to download the file instead, click here to download
