How to set file type .swf to open in shockwave plugin
Firefox 61 on Ubuntu. When I try to open .swf files, it tries to use the system's video display application, which cannot handle it (because it's not a video).
In Preferences->Applications there are 3 entries for SWF file type: application/x-shockwave-flash and application/futuresplash which are assigned to Shockwave Flash plugin, and application/vnd.adobe.flash.movie, which is assigned to Videos (and does not has an option for the plugin in its drop-down menu).
Somehow, all SWF files are assumed to be of the last type, which does not work. How can I assign all SWF files to the plugin?

Shockwave Flash is old name for Flash Player so no it s not related.
You can check the handlers.json file in the profile folder.
You can also check all involved MIME types in the OS.
- xdg-mime query default <MIME type>
Thanks everyone. I should have said that I'm aware that newer versions of Firefox block the Shockwave plugin by default; I have already taken care of that. This plugin did work before, it's just that the mime type which is assigned to SWF file type does not use it.
xdg-mime query shows that indeed all .swf files are assigned to mime type application/vnd.adobe.flash.movie. It seems the trouble had started with installation of a new video application, which might have messed up file type.
So the question is really how to restore the association of .swf file extension with mime type application/x-shockwave-flash, and / or how to convince Firefox to use the plugin for all mime types which are associated with SWF files?
Thanks much.
