[Plugin: WordPress Download Monitor] Problem with Firefox

Hello,

I’ve performed the upgrade some years ago, but only today I’ve discovered that the download it’s not possible con Firefox (it reopen the download page when I go to a download file) meanwhile everything is okay. Please can you help me?
And in the case there is no solution, is it possible to come back to a previous version of Download Monitor wihout lose something?

Best regards
Marco
