when viewing a video on the newest Firefox version it runs two simultaneous versions of flash in my task manager-----this is maxing out my cpu which results in the video running slow and glitching----how do i disable one of the flash plugins from running?
There are multiple Flash Player processes running?
I believe this is how the protected mode feature works. It splits various Flash processes out of plugin-container.exe into independent processes. Although protected mode has some theoretical security benefits, it is buggy and I recommend disabling it.
If Windows gives you problems with permissions, try this way:
(1) In a My Computer or Windows Explorer window, open this folder:
If that folder does not exist, then you are using 32-bit Windows, and you can open the following folder instead:
(Note: This folder exists on both 32-bit and 64-bit Windows, but on 64-bit Windows Firefox uses the Flash player in the SysWOW64 folder instead.)
(2) Check for a file named mms.cfg:
Note: If you do not see file extensions such as .ocx, .dll, .exe, and .cfg on the files in this folder, then Windows may be hiding these from you. In order to work with file names accurately, it is best to unhide the extensions. This Microsoft support article has the steps: http://support.microsoft.com/kb/865219.
(A) If mms.cfg exists, drag it to your Documents folder where you can edit it without being bothered about administrator privileges
(B) If mms.cfg does not exist, open your Documents folder, right-click > New > Text File and name the new file mms.cfg
(3) Open mms.cfg from Documents into a text editor such as Notepad.
Add this on its own line (I put it last):
Save the file and close Notepad.
(4) Hold down the Ctrl key and drag the mms.cfg file back to the Flash folder to make a copy there, keeping the original in Documents
This change will take effect once the Flash plugin is completely unloaded, which may require exiting and restarting Firefox (allow a few minutes for all the Flash processes in memory to terminate after exiting Firefox).
There is a specific reason why there are two Flash processes (actually three if you include the plugin container EXE too) running for the video you are seeing. This is to ensure more stability for Firefox - so that any glitches in Flash player don't cause issues on Firefox. This also provides higher security wherein the Flash exe has more restrictions on it.
