Control panel, security, remote-settings; Allow remote Assistant ...
</p><p>I swear I had unchecked that box months ago. I went looking because of the phony-update malware and my investigation of jquery.min.js where some code is used by many sites from the <a href="http://ajax.googleapis.com" rel="nofollow">ajax.googleapis.com</a> site dynamically, and some user wanting to change files on a machine and an answer was to lower the security settings.

After a lot of troubleshooting, I found the culprit of this problem:

</p><p>After a lot of troubleshooting, I found the culprit of this problem:
Today I tried opening a .pdf file and the exact same issue occurred which made me think that there was something else going on. So I did a reinstall and everything worked fine again. After the reinstall, I did my normal post installation routine: install addons, settings tweaks, about:config tweaks.
</p><p>After that, .swf and .pdf files stopped working again. Long story short, this problem is caused by the BetterPrivacy addon. Now I can imagine someone might think "duh you could have figured that out easily by starting Firefox in safe mode and/or uninstalling your addons in your troubleshooting process". The problem is, that I already did all that but once you have installed BetterPrivacy one time, it screws up your configuration somehow for good even when you already uninstalled the addon and/or tried Firefox safe mode.
</p><p>Anyway, the fix for this is uninstall BetterPrivacy, close Firefox AND delete the Firefox prefs.js file. After that, you can restart Firefox and all is working again.

And I'll guess that developement is also done for free by well meaning people. It's possible something has changed inside (on Win10?) or something you had on another machine or OS did not make it over or work the same on an OS upgrade.
</p><p>You specified .swf files. I have the situation that swf files play, but if they are on one certain web site, they will NOT. I have to use (cough cough) IE to view them. I'm living with it. I really only wanted to state the first two sentences.

Anyone else from Mozilla staff? This issue should be fairly easy to reproduce imo.
