of course I've got my flash player on : http: // get.adobe.com/fr/ flashplayer.
So every time I use flash player on firefox I Have this script from https://fbstatic-a.akamaihd.net/rsrc.php/v2/yy/r/GN23mC2ZFkG.js:13
and cookies coming on all navigators Safari Firefox Chrome : Akamaihd
So if I disable Flash player no more problem, so there officially a problem with flash player and made a correction with version 16.0.0.305 but the problem is not solved because there is still a security hole in flash player !!!!!
So what the solution, if staff doesn't know about this security hole in flash player ???? STRANGE
I wanna have a solution ....
bcause of this I reinstalled my computer with fresh yosemite not problem during 2 days and after intalling flash player problems are coming back, so for the moment I have uninstall flash player : no more problems...
So the problem is coming from flash player, so ADOBE HAS TO SOLVE THIS MATTER and make a new version of it!
