Uploading files using FF is not working

[James]

Flash has been a thorn in our side since FF 1.0. It's time FF developed a native way of playing Flash content, the way it does PDF's, but I don't know if that's possible, not being a programmer.

Since before Fx 1.0 as the web browser existed since 0.1 Release in Sept 2002 (when it started as Phoenix) and not as of Fx 1.0 in Nov 2004 as many incorrectly think.

Mozilla did have Shumway however it was retired early last year.

FireFox just had another update today but no joy with the flash compatibility again.

Fx 52.0.3 came out on May 19 while 53.0.2 was released on May 5th.

Just because some seem to have Flash Player issues does not mean there are compatibility issues with Firefox. And please do not say well I tried insert random older version and it seems to work fine now. Note Firefox and SeaMonkey uses the NPAPI version while IE uses ActiveX and Chrome uses PPAPI version so a comparison is not the same.
