Does the Adobe test page show the Flash plugin?

Does the Flash plugin show in "Tools > Add-ons > Plugins"?

Hi Team

Thank you for sending me the information, from the links you sent through, I am apparently running a new version of flash Version 11,8,800,115 installed.

With this in mind I could see that the only thing that it could be was some sort of protection, as I noticed that I was seeing 2 flash processes running in task manager, ie flash running in protected mode. So I edited my mms.cfg as per instructions, Firstly I have backed up my original mms.cfg and copied into new (my docs due to UAC saving issues) and edited adding the line ProtectMode=0. Saving and copying from my docs back into Macr..../flash folder under UAC and refreshed firefox and now appears to be working for the first time in weeks. Thank you...this is why I love FireFox...support when you need it.

Feel free to post online to help others...

I have the same problem as "cj_gadget" but with a Macintosh configuration, so the solution may be different!

After a long period without using it, this iMac (running with Mac OS X 10.6.8) has been recently updated with the most recent versions of Firefox (25.0) and Flash Player & Plugin (11.9.900.117). The result is that Firefox freezes on every page with Flash content. For other reasons, I have to stay with Mac OS 10.6.8 without upgrading to more recent OS versions. I have looked through Firefox and Adobe Flash Player help pages, as well as through many posts on this forum without finding an effective solution.

Following some of these posts, I have unchecked (in Firefox > Preferences > Advanced) the use of hardware graphic accelerator. Many posts advise to do the same for Flash Player with a right click on the video frame, but this is NOT possible since Firefox freezes immediately as all Flash video start automatically when the page is loaded.

I have also checked that a HTML5 video displays correctly as for : "http://www.youtube.com/watch?v=cTl3U6aSd2w&html5=True" while "http://www.youtube.com/watch?v=cTl3U6aSd2w" stucks Firefox. This Firefox freezing problem is general for all pages with Flash content (that is for a large fraction of the Web!) and NOT limited to Youtube which was just used here as an example.

Some more information : RealPlayer was not present on this computer when the problem appeared. If I disable the Flash pluging in Firefox, it does nor freeze, but of course does not display the video. Safari (version 5.1.10 - ok for Apple software update) works fine with Flash content.

I have sent many hours on this problem without progress and would strongly appreciate any help or even better a solution !
