Can't print from Flash in Firefox

[shasimo]

Hi everyone

I'm having an issue with my longtime running Flash applications, from which I have always had a print button that worked without any problems.
Now I discover that it no longer works in Firefox. I hit the button in Flash, print dialog shows, I hit 'OK', print dialog disappears and nothing happens

In Crome there's no problem, but...
Can anyone help me with this ?

Do you happen to have the bug number?  Any idea when this broke (eg. with this weeks release of Flash Player, latest release of Firefox, etc)?

I'm not sure as to when the problem started - sorry.

It's more likely that this is a Firefox bug, but we'll take a look and forward the bug on as necessary.

Thanks!

We know a little more about this now, and I believe that 64-bit Firefox would be a viable workaround until we can ship a patch for it.

If you're on a 64-bit version of Windows, you can try upgrading to 64-bit Firefox.  You'll also get a much better experience from Flash and Firefox in terms of stability, performance and security.

I'll do that, and maybe it will help, but according to a vote, that was added to my bug report at https://tracker.adobe.com/#/view/FP-4198297​, using 64bit version of Firefox won't eliminate the problem.
Also it's not so much myself who's troubled by this - it's the end users of my apps -  I have several running apps like the one in the example.

I've experienced the same problem with Firefox 64bit under Windows 8, meanwhile Firefox 32bit and Internet Explorer work fine. Under Mac OS X instead Firefox 64bit has no problem.

I've opened a thread on the Firefox Forum to ask if this is a Firefox or an Adobe Flash bug: http://forums.mozillazine.org/viewtopic.php?f=38&t=3031163

Let's see what they say.

Hi

This worked for me

in firefox go to addons >

find "Shockwave Flash" and select options next to it

disable "Enable Adobe Flash protected mode"

Restart Firefox

Cheers

Disabling protected mode on 32-bit Firefox puts you at a significantly increased risk for contracting a malware infection.  It's a terrible idea in the context of 2017 (you're basically rolling back to the state of browser security circa 2010).  It's unfortunate that recommendation continues to live on in support documents and the common lore.

You're far better off with one of the following options:

1.) If you're on 64-bit Windows, use the 64-bit variant of Firefox on Windows, which includes a native NPAPI sandbox, eliminating the need for Flash Player's own sandbox.  You'll also get a much better experience from Flash and Firefox in terms of stability, performance and overall security in both the plug-in and browser.

2.) Use Chrome or Edge
