Does anyone know what libraries I have to install to play .swf files?
You can use the standalone flashplayer by Adobe : https://help.ubuntu.com/community/FlashPlayerStandalone
But you can also open the file in your Internet browser if you have installed flash plugin.
What worked for me is going to the adobe site and then selecting
Download the Flash Player Projector (64-bit)
Then extract the contents,inside the extracted folder there is a file called flashplayer open it. Then CTRL+O to open the file locally isntead of typing it as a url.

Here are steps in resume:

How to open a .swf-file with Firefox browser
Right-click on the file. Choose

It will open in the Firefox and play itself. I assume the flashplayer-plugin is already installed in Firefox, else it will ask you to install flashplayer-plugin. Follow the steps and you are good to go.
In order to locally open

78+), old methods wouldn't work, e. g. changing/replacing entries of
application/vnd.adobe.flash.movie with appropriate entries for
application/x-shockwave-flash (or creating the latter, where the former was missing).
in FF' Shockwave Flash plugin's settings, enabling
applying the above in FF' profile folder's 'mimeTypes.rdf'
creating file ~/.mime.types with entry:
application/x-shockwave-flash swf swfl
vnd.adobe.flash.moviewith that entry in
replacing/adding an appropriate entry for
<mime-type type="application/x-shockwave-flash">to /usr/share/mime/packages/freedesktop.org.xml
So, even with
xdg-mime query default application/... pointing to
.desktop starter configuration file, for both

to execute local
.swf files in Firefox (with some of the above maybe
still required beforehand):
Replace following entry in FF profile folder's file handlers.json (mind replacing exactly between the correct 2 commata!)
Disconnect from the network (!)
Temporarily reset the desktop's system date, back to before the official EoL date (< December 31, 2020) of FlashPlayer, or else it will attempt redirecting to Adobe's EoL website (!)
Now finally 'enjoy' playing your favorite local SWF / FlashPlayer files!
After finished, restore the original system date (!)
NOTE: There might be a problem with all add-on's disabled after a restart, if restoring the original system date before hasn't occured before (or while FF trying to update its components, unless disabled before).
To fix this, reset all of Firefox' registry entries, starting with
P.S.: It might be arguably a 'good idea', to store away a copy of the last version (32.0 r0 / 18.104.22.1685) of Shockwave Flash player's binary from /usr/lib/flashplayer-mozilla/libflashplayer.so - you never know, it might vanish from the repositories someday. But then, Mozilla could also blacklist the plugin completely.
Also, if somehow it doesn't work out, you might check for the following
registered mime type in the
Shockwave Flash plugin's settings in FF:
application/x-shockwave-flash (Shockwave Flash: swf)

To execute a local

Due to the notorious security problems history with Flash Player, use this method at your own risk! It's generally a bad idea, and most especially, to download new
.swf files from dubious websites and executing them. This method should be used with caution, and only if you 'know what you're doing' !
