javascript - Detecting if AdBlock extension is installed on the browser -

-

i need detect if adblock extension installed on user's browser.

i have seen similar question on so, of them suggest check if dom has been modified.

i rather want check if extension installed (maybe javascript ?) on browser rather check dom. how do ?

try global navigator.plugins variable. loop should work. (js)

nice blog topic: http://webdevwonders.com/detecting-browser-plugins/

edit: chrome can try if app guid.

try {     var appguid = "nnbmlagghjjcbdhgmkedmbmedengocbn";     = new image();     a.src = "chrome-extension://"+appguid+"/icon16.gif";     if(a.width != 0) {        //app installed!     } } catch(e) {    //app not installed }
