Here’s a small but useful post for people, who use Internet Download
Manager and have recently moved to Firefox 9,10,11,12. The old Firefox
add-on that came with IDM is not compatible with Firefox 9,10,11,12.
There are alternative solutions on the internet like the FlashGot
extension. Anyhow, it’s a simple matter of a new add-on. Download the
add on below and install it on your Firefox 9,10,11,12 browser.http://www.internetdownloadmanager.com/idmmzcc/idmmzcc.xpi
1- Open Firefox,
2- Paste the link to the address bar 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 one hosted on my site with the latest version. This works with Firefox 9,10,11,12 as well.
