Somehow flash player has gotten inside Tor and I do not like it. It offered one-click enable flash, but it doesn't state its risks and how long it will be enabled. I don't want to give up privacy for any videos, in fact, I want flash player to never attach itself to Tor browser in the first place. I want to have no way of enabling flash player in Tor browser as long as it does not offer privacy by design(read: forever). And also how did this function appear? Was it the Tor update or the flash player update? I can't believe they did not even notify the users how much privacy they give up by this feature.
Are you using Windows 8? If so, I have the same problem. Apparently, Flash installs itself into your Windows 8 system through a software update. I found this walk-through on how to get rid of it from your machine. Hope it helps: http://betanews.com/2013/01/10/you-can-remove-adobe-flash-from-windows-heres-how/
You don't say what OS you're using. If you're using Windows, you can just prevent plugins from loading from the Windows registry in the Tor Browser (which is actually Firefox). I have tested this on Windows 7 with the Tor Browser Bundle v. 3.5.
To prevent the Tor Browser from loading plugins start by typing
about:plugins into the browser to see what plugins you have installed. In this case, you should only see Flash installed.
about:config into your browser and then set the preference
plugin.scan.plid.all to false. If you check
about:plugins again, you will see that Flash is no longer listed. When you relaunch the Tor Browser, Flash will be gone.
