Flash doesn't work in Firefox 13

Question

Installed Firefox 13 yesterday. Now flash doesn't work. Have done all the supposed fixes to no avail. Have uninstalled and reinstalled flash. I'm at my wits end with this issue. I'm a web designer who uses flash in a number of my sites. VERY IRRITATING when my sites don't display properly. Anyone have a solution other than the pat Mozilla "fixes"?

I received a PM from '''CheckMate''' about this thread. Since this is something that I think should be discussed openly I'll reply here.
The ActiveX plugin (npmozax.dll) issue is now fixed via the Mozilla blocklist, which automatically disables it. For some background on the ActiveX plugin issue, see [https://support.mozilla.org/en-US/forums/contributors/708425 Blocking the old ActiveX plugin] in the contributor's forum thread.
The Flash 11.3 Firefox protected mode problem is a separate issue and one related bug is [https://bugzilla.mozilla.org/show_bug.cgi?id=747683 747683] So, if you did have the ActiveX plugin installed and it is now disabled, AND you have Flash 11.3 installed, then the issue is no longer the ActiveX plugin.
If the problem is Flash 11.3 protected mode (or other issues with Flash 11.3) it's not a good idea to suggest downgrading to 11.2.202.235. The reason why uninstalling Flash and going to a page that requires Flash installs an older version is because the Plugin Finder Service hasn't been updated yet! This is from http://kb.mozillazine.org/Flash#Installing_Flash_on_Windows <br>

''If the Flash plugin is not installed and you visit a page that has Flash content that requires the plugin, the Plug-in Finder Service can download and install Flash for you (see [https://support.mozilla.org/kb/Installing+the+Flash+plugin Installing the Flash plugin (Firefox Support)] for more information). If you want to try this method and Flash is already installed, you can [http://kb.mozillazine.org/Flash#Uninstalling_Flash uninstall Flash] and then visit [http://www.adobe.com/software/flash/about/ Adobe's Flash test page] to launch the Plugin Finder Service ; however, it may offer you an outdated version.''
The alternative (disabling Flash 11.3 protected mode by editing an obscure file) is not good either. I don't know what to suggest in those cases. I think it would be a good idea if you could bring this up in the SUMO Community Discussions forum. There's already a topic started on Flash 11.3 issues, here:

Here is your original message, for reference:
''Hi, Alice- You locked the thread on the Adobe Flash Plugin update 11.300.257 not working question but you really shouldn't have for the following reasons. First, although I too found today that the Active X has been blocked as of June 7, the problem persists and the instruction is to contact the manufacturer. How about contacting Adobe and straightening this out on the Developer level instead of closing the thread because there's another temporary but much simpler solution that I found. Second, the instructions on how to disable Protected Mode are nuts. I'm pretty advanced, but my common sensed tells me this is too complicated to bother with and shouldn't be necessary and you yourself say this isn't a permanent fix. Third, I found a much simpler solution, at least until this bug is fixed. Completely uninstall the Plugin from the Add and Remove Programs list. Then, when you try to access any video on YouTube which uses the Plugin, Firefox reports that it needs an additional Plugin to play the video (look specifically for the FF blue plugin icon). When you click on it, it automatically downloads the PREVIOUS VERSION, 11.2.202.235 which works perfectly. But if you click on the warning below it that Adobe Flash is needed, the buggy 11.3.300.257 version will be installed again! This has to be fixed by the Developers. Until it is, the fix is simply to roll back the faulty update, which could have also been done with a restore point but I wanted to find the cause. FF apparently knows automatically that this plugin is faulty and installs the previous version, but the other instruction is contradictory and installs the 11.3.300.257 Nice!?!? ''
