Most of the people use IDM (Internet Download Manager) to download files from internet. No doubt, IDM is a great software and is much better than other such applications. One of the best thing about IDM is, it integrates itself to all the browsers. However, recent upgrade of Mozilla Firefox makes IDM incompatible to Firefox 7. This has been happening since the release of Firefox 3. The reason behind this bug is, Mozilla team is unable to find the update of the Internet Download Manager addon for IDM.

Anyways, good news is IDM does support the latest Firefox 7 but you have to manually install the updated and compatible IDM addon. I have come up with a very simple yet useful tip that makes IDM compatible to Mozilla Firefox 7.
