Flash Player Plugin starts multiple processes

Hello,

I’m experiencing problems with my Flash Player Plugin (11.9.900.52). As I’m no IT expert, I’ll provide a tentative description of the problem. I probably should start with my system. It’s Windows 7 32-bit system. I’m using a Firefox (25.0.1) browser. And now with the problem. When I start up Firefox, 2 Flash Player Plugin processes show up in the task manager. Every time I open a webpage using Flash (or in fact start a second Firefox window), 2 additonal Flash Player processes commence. However, even when I close a tab using Flash or I close Firefox completely, the Flash Player processes do not end (I guess) and do not disappear from the task manager. The problem is preposterous! Yesterday, after a couple of hours of using my PC I had more than 600 Flash Player processes running!

Furthermore, Firefox often informs me that the Plugin is malfunctioning. There are some errors, the browser freezes for a moment and then starts functioning “normally”.

I tried to reinstall Firefox, Flash Player, check whether everyting is okay with the plugin, but from what I see and am capable of doing, there are no apparent problems.

Do you have any ideas what can be the source of my problem? Obviously, I can provide you with more information, but I have no clue what else I can tell you at the moment.

I tried to find a solution to this problem, but I couldn’t find anything.
