The following website for example:

What i do the erase all traces:

  1. Firefox -> Clear history -> All (cache,cookies,history,..)

  2. Deleting Flash cookies manually (AppData->Roaming->Macromedia->FlashPlayer)

  3. changing mac-address -> becomes changing IP address

NO PASSWORDS are saved in Firefox for these Websites.

I am clueless how those few websites can identify me even after doing all that.

Why they still identify me?? Is there something new?

When you say "recognize data" what kind of data are you talking about? – wizlog Feb 8 '12 at 1:53

There is a second location


%APPDATA%\Roaming\Macromedia\Flash Player\\support\flashplayer\sys\



Maybe they are fingerprinting your browser.

i knew that, thats common knowledge. Thats why i wrote: AppData->Roaming->Macromedia->FlashPlayer. the reason is definetely not flash-cookie based since i stressed that out by disabling flash. Also i don't think that a company like myopenid would identify me by easy hackable javascript characteristics like screen,resolution etc. its my login we are talking about. thax though for your answer – Email Feb 8 '12 at 17:42
Login information is always stored in a cookie or a browser, so something is lingering on your system.."common knowledge" you obviously don't answer many questions here or on forums, I assume nothing, besides you stated you were clueless. ;-> – Moab Feb 9 '12 at 4:00
