Can’t integrate IDM into Firefox? We’ve got you covered with a solution here. We’ve already covered how to set IDM to pickup downloads initiated from Chrome browser, we realized Firefox users too have Internet Download Manager integration problems.

After installing the update for Firefox, which IDM claims it supports, it downloads files from browser, however, shows an error now and then: ‘You have an obsolete Firefox Browser Integration or Firefox integration is not installed. Would you like to read how to fix it?’. If you click ‘yes’, it takes you to Firefox integration help page on the IDM website, which doesn’t help much.
