For several Torbrowser versions & Flash Player versions, I've randomly found flash files running in background, when no Flash content was played, nor was there any user request to start Flash player or download / install it. It's happened perhaps 12 or more times, easily. It took a long time to figure out what may trigger the files to start in background. In both TB & vanilla Fx, the Flash plugin is & always has been disabled. The only reason it's installed, is for rare use in vanilla Fx. No way to "uninstall" it only for Torbrowser. * Maybe there should be a method, by default, to block Flash plugin from *automatically* showing under Torbrowser, if Flash is installed for other "plugin-based browsers." Unless users specifically request it. I'm reporting this, because others may use Flash in Firefox & may be unaware if Flash files start running in background under TB (if it actually happened). I may just uninstall Flash, but this still needs reporting. I finally determined when the flash files start in background, it's (sometimes) very soon after page was visited that had flash content. But it doesn't happen on all pages w/ flash content (where Flash files wind up not being played, by any method, e.g., html5). I do NOT play or attempt to play the flash files in TB, the times when Flash files start running. On the sites where the files DO start in background, appears all I must do is LOAD the page w/ flash content. The websites report that Flash is disabled or not installed (it IS always disabled). The times the files start in background, I did NOT play any Flash content in IE (don't use it), or vanilla Fx. I've confirmed that many times. Besides, the processes are ALWAYS listed under the *TB Plugin Manager* process, never vanilla Fx. I don't click anything on the webpages to download or install Flash. I don't attempt to play Flash content, then "back out" (would be impossible w/ Flash disabled). The command line for one of the background files looks like: "C:\Windows\SysWOW64\Macromed\Flash\FlashPlayerPlugin_12_0_0_77.exe" --channel=4128.0027F650.1150601763 --proxy-stub-channel=Flash5736.60497F48.24779 --plugin-path="C:\Windows\SysWOW64\Macromed\Flash\NPSWF32_12_0_0_77.d ll" --host-npapi-version=27 --type=renderer (this was for a previous Flash ver., but still does it w/ later ones) Don't have the full command line for the 2nd Flash process, but it contains the same "FlashPlayerPlugin_x.x.x.exe\...\NPSWF32x.x.x.dll." **Trac**: **Username**: joebt
