This script bypasses detection of Flash Player on websites using SwfObject.
Since Firefox version 69, the "Always Activate" option was removed from Flash Plugin settings. Instead, each time a Flash content appears on website, we have to activate it manually. This change also broke detection of Flash Plugin, and some websites ask us to download it, even though it is already installed.
I made a quick and dirty script to override the detected Flash version to 32.
Note, this works only if you have Flash Player installed, and with option "Ask to Activate" ticked in Plugins Manager.
Tested in Firefox 70.0.1
