    • do any of the installers now recommended mess with the protected mode setting ? (And is that still important for some Windows users ? )

    I've had protected mode disabled (ProtectedMode=0 line in the C:\Windows\SysWOW64\Macromed\Flash\ mms.cfg file) through many updates and it's never changed. I use the .exe plugin installer link on the Adobe Flash Player Distribution page to update Flash.

    I leave Flash protected mode disabled because of how badly the focus bug (bug 768802) affects SeaMonkey when you don't disable it (see this mozillaZine forum thread).

    • We contradict ourselves

    We suggest downgrading to Flash 10.3 as a workaround, when the latest Flash version is causing problems or if updating RealPlayer doesn't resolve Flash video display issues. An alternative to downgrading Flash on Windows Vista and above, which SUMO doesn't recommend (not sure why not ... too complicated?) is disabling protected mode. We refer users to this adobe forum post or to this section of MozillaZine's Flash article for that.

    I see you took out disabling protected mode in Flash 11.3 doesn't load video in Firefox so now that article and the new Adobe Flash plugin has crashed - Prevent it from happening again article both recommend downgrading to Flash 11.2.

    Hey Alice. Just catching up on some stuff here. In response to this question and the previous one, this issue got really out of control on Friday. We consulted with some other groups at Mozilla and it was decided that for Crashing issues specifically, the best course of action was to rollback. The flash not playing issue is still believed to be realplayer related. Since rolling back to an older version is now being offered as a last resort for the flash not playing issue, the disabling protected mode steps just seemed redundant. We were concerned the article would be too long and people wouldn't use it

    Can you give a reason why we should add disabling Flash protected mode for troubleshooting purposes, as an alternative to downgrading Flash?

    Disabling protected mode in the Flash mms.cfg file might be too complicated for many users but it may help others. I'm on the fence.

    This is one of the "Related Questions" links that this article includes in the sidebar:

    This is a long thread with many "me too" posts. Cor-el gave his usual answer for Flash issues:


    You can check for problems with current Flash plugin versions and try these:
    
       disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
       disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
       disable hardware acceleration in the Flash plugin 
    
       http://kb.mozillazine.org/Flash#Troubleshooting 
    

    jscher2000 also gave this reply on page 3:


    (1) If you use any recorders/downloaders that interact with Flash media, make sure they are as up-to-date as possible, or disable them temporarily.
    
    (2) Disable hardware graphics acceleration in Firefox and in Flash
    
    (A) In Firefox, un-check the box here and restart:
    
    orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"
    
    (B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues
    
    (3) Disable protected mode (Windows Vista/7/8)
    
    See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox? 
    

    ...and he added this in another reply,


    To ease editing the the mms.cfg file, you can drag a copy (hold Ctrl while dragging) to your Documents folder where you have full read/write privileged. Then edit the file there. Then Ctrl+drag it back to the Flash folder. Hopefully that will work for you. (Full steps listed here: https://support.mozilla.org/en-US/que.../973998#answer-489685) 
    

    Right now, the only place we mention disabling protected mode is in the "Recent Flash issues" canned response: Forum Response - Flash problems ...which says this:

    I am strongly in favour of having disabling protected mode mentioned in one of the kb articles that we may link to. This is especially so now that we may expect the user Carm to post recommending a software solution employing this in near enough every AAQ thread posted relating to Flash.

    I have amended the canned response but not self approved.

    No article now recommends trying disabling protected mode.

    This step was removed because there was the option to downgrade, but that option no longer a recommendation because 10.3 is EoL.

    Flash 10.3 is EOL - removed solution recommending downgrading to 10.3

    Is this still a valid possible trouble shooting step that users should be aware of ?

    This is a case where it may be handy to have a good advanced search for the forum, as it can filter for solved threads, I am not aware google can however a glance at some results from this search would suggest it may still be a suitable method to try

    Starting in Firefox 35, you can disable Flash Protected Mode by setting the dom.ipc.plugins.flash.disable-protected-mode preference to true in about:config and restarting the browser (bug 1108035). To re-enable Flash Protected Mode, reset the preference back to the default "false" value. At time of writing, however, this option does not work on Windows 8. https://bugzilla.mozilla.org/show_bug.cgi?id=1112709 http://www.ghacks.net/2014/12/21/how-to-disable-flash-player-protecte...
