Firefox 26, javascript true in about:config, but no adobe flash plugin saved?
While adobe flash 11.9 is being downloaded YouTube video is playing back without buffering time. But as soon as the download is being installed (7%), the downloaded install file disappears from the download folder and different error messages appear during each install attempt.

hello michla, when you can download the flash installer alright in the first place and only get errors while you run the flash setup, this doesn't sound like a firefox problem in particular. you can consult adobe's help section about common installer errors: http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html
