If your system shows an error when trying to play flash videos in Firefox, and you have our Downloader extension installed, you have run into a compatibility issue with Adobe’s latest Flash release. You can fix the issue with playback and use the RealNetwork’s Video Downloader extension in Firefox by disabling Adobe Flash’s protected mode. To do this, you must edit Adobe Flash’s mms.cfg file. On 64-bit windows, you can find the file in C:\Windows\SysWOW64\Macromed\Flash On 32-bit windows, the file will be in C:\Windows\System32\Macromed\Flash To edit, first close Firefox. Next, open Notepad in Administrator mode as seen in the video (You don’t need to open the file with special permissions on Windows XP). Then, open the mms.cfg file from the appropriate directory. Add ProtectedMode=0 to the last line in the file. Save and close. You will have to repeat these steps and delete this line to re-enable protected mode.
