https://support.mozilla.org/en-US/kb/end-support-adobe-flash says Firefox 84 still supports Flash. Yet on some learning websites that use Flash still, like alison.com but it doesn't really matter where right, it shows this where the flash app should be and all blank white around it: (see "capture" screenshot below) And I can't click on it nor is there a pop-up bar nor a little plugin icon at the beginning of the URL / address box to click on. How do i enable it? I found this: (see "extensions,plugins,shockwave_flash" screenshot) Am I close? :)
