[SOLVED] How to play .swf files?

Apparently I have not had reason to read swf files for long time.
I remeber i could years ago.
Now me and my son is building the legendary Reprap Darwin 3D printer version 3.0 kit, and some instructions are in swf.
vlc plays the sound and on some files i have some more or less distorted still picture.
lightspark say file is SWF version 8 not handled by lightspark and try to launch gansh which is not available
trying to use firefox, it "downloads" the local file instead.
After applying the known fix
https://askubuntu.com/questions/478169/ ... -swf-files
first i tried the tip there on the mime spec file in my home, reasult is that firefox repeatedly opens a new tab...
Undid tha tand tried theother fix there which is also here:
http://superuser.com/questions/687414/f ... -swf-files
http://superuser.com/questions/726789/f ... of-opening
https://bugs.chromium.org/p/chromium/is ... ?id=369015
Result then is that OK it stopped to download it and instead launch vlc - which as said fail.
(despite i found a setting in firefox that it should open it internally in the window)
Then i got the idea to try chromium-browser as that have internal flash, or is that old news.
Result it that it calls firefox, that in turn start vlc... AAAHH
BTW i tried all above in cauldron, and some of it on mga5
