I need to temporary disable IDM to download some file with my browser. How can I do this?

If you want to temporary disable IDM for single download you may hold Alt button while clicking on the download link to prevent IDM from taking the download. If it does not work, read here how to configure keys to prevent IDM from taking a download.

Or you can temporary turn off IDM integration into a browser in "Options→General" IDM dialog.

Disable IDM integration in your browser

You may also delete this file extension from the IDM extensions list in "Options→File Types" dialog (arrow 1 on the image). Or you may add this server to the exceptions list in the same dialog. To do this press "Edit list" (arrow 2 on the image).

Delete file type extension

Then press "Add" (arrow 1 on the image), enter a site that you do not want to download with IDM from and press "OK" (arrow 2 on the image).

Add exception for some Url

Please note that if you want to prevent downloading from entire site you can use asterisk ("*") after site name like "mysite.com/*" or after some path like "mysite.com/articles/*".

In the latest version of IDM if you cancel downloading of any file twice, IDM will automatically suggest you adding it to the exceptions list.
