Adding an extention
Previously I was able to add IDM (internet download manager), but now I get the message, "does not support IDM " Will this be changing? If not, how do I go back to the previous version of Firefox. If I can't use IDM, then I will go back to Chrome.

There are several programs with that name. Can you give us the link to its webpage?
What's your Firefox version?
Firefox 60.0.2 (64-bit)
That is a third party program. Check at its support.
