So, I need plugins to associate odt files, doc, avi, mp4 and others to their respective programs. Recently migrated to the opera browser and I'm missing these features found in firefox and chrome. Another difficulty I'm having is with netflix, I could not even make it work.

Hello,
I have the opera version 39.0.2256.48 installed on debian stretch and can not associate .avi .doc and others to their respective programs. Every time I click on a link to these files, the opera opens the download box.
