During prox. last half a year, Mozilla Firefox Web browser jump from one major version to another... Unfortunately Adobe Acrobat X Plug-in for Mozilla Firefox is not so quick in its own updating (prox. only one time in 3 months or so), to simply follow compatibility with all this new Mozilla Firefox new version explosions... Also, before, when you enter Private Browsing mode in Mozilla Firefox, most like in IE, this Adobe Acrobat X Plug-in would not shown/would not be engaged in the Private Browsing mode... Only in normal mode will... But, as of the last Adobe Acrobat X v10.1.2 Update, the Adobe Acrobat X Plug-in for Mozilla Firefox is not disengage anymore during the Private Browsing in Mozilla Firefox v10.0.2, only in IE InPrivate Browsing Mode still is... My question is, is it this OK (concerning privacy issue), or, how to setup, that, only in Mozilla Firefox Private browsing mode, the Adobe Acrobat X Plug-in will disengage automatically, and when you run in the Mozilla Firefox Normal browsing mode, he will be still automatically available? Thanks everybody for help in advance!
