So you either kill the process or just wait. Although the window doesn't show the familiar "-not responding" in the title, nothing responds, not even minimize. Mozilla freezes really randomly, for a long period of time and it has nothing to do with specific sites, although it does it more often on Youtube for me. Since there is no alternate for disabling protected mode, myself and all 4000 of my colleagues have no options for fixing this freezing problem.Ĭan you please solve this issue by either 1) working with Firefox so that the browser will no longer freeze when Adobe Flash player is installed, enabled, and protected mode is enabled, or 2) make protected mode a configurable feature that can be enabled or disabled by any user group in Windows Control Panel.I experience the same problem too. The company I work for has all computers without such admin privileges. The method of adding a line to the mms.cfg file requires users to have admin rights to editing files in the \windows\system32 directory structure. Unfortunately, the method available for disabling protected mode will not work for myself or anyone else that works on computers issued and supported by my Fortune 500 company. There are many reports that the freezing in Firefox can be solved by disabling protected mode in Adobe Flash.

I have read on the web that many other Firefox users in the Win7 environment have the same problem that Firefox freezes when Adobe Flash is installed and enabled. In order for me to make Firefox usable, I always disable the Adobe Flash plugin. I am 100% certain that flash is the source of the Firefox freezing problem because I can cause the Firefox freezing to stop and start again by disabling and enabling the Adobe Flash plugin. This same problem has existing for at least the last 5 versions released by Firefox and Adobe Flash Player.


I am using the latest version of Firefox (v19.0.2) and the latest version of Adobe Flash (v11.6.602.171). Flash player is causing Firefox to freeze for about 30 seconds whenever I access a website which uses flash.
