Assuming Adobe makes flash for Linux - it will have it's own default install locations that it install to. It doesn't install into the newer version of FF as it does in the past and flash only is used if the site uses it otherwise FF doesn't by default use Flash. Otherwise you need to contact Adobe support for flash install problems.

Hi,

You can download Adobe Flash here :

https://get.adobe.com/flashplayer/otherversions/

And choose 'Linux' - it will be installed on your system, and you'll see it in Firefox 3-bar menu => Options => Add-ons => Plugins, where it will show as 'Shockwave Flash'

I'm running Open Suse Leap 42.3 and have installed the firefox directory in /usr/local/firefox (from the tar.gz file from firefox). I do not see however a plugins directory in firefox to install the flash plugin in (libflashplayer.so). To which directory do I have to copy this plugin. Thanks a lot in advance

It looks like you downloaded the tar.gz file from https://get.adobe.com/flashplayer/

If you are the only user then a easy way is to create a plugins folder in /home/<user>/.mozilla/ and place the libflashplayer.so in that plugins folder.

If Firefox was still running when you do this you can either restart Firefox or type about:plugins in the Location (address) bar so Firefox will scan for Plugin.

Note that you can use the 64-bit RPM Flash installer on openSuse.
