Here’s a small but useful post for people, who use Internet Download Manager and have recently moved to Firefox 4. The old firefox addon that came with IDM is not compatible with Firefox 4. There are alternative solutions on the internet like the FlashGot extension. Anyhow, it’s a simple matter of a new addon. Download the addon below and install it on your Firefox 4 browser.

1- Open Firefox 4,
2- Paste the link to the addressbar and Go,
3- Wait for the download,
4- Restart Firefox,
5- Enjoy.

Alternatively, if the above link doesn’t work for some reason or is an older one. Here’s on hosted on my site with the latest version.
