I have three google users [personal, work, work] in my chrome on Mac OS X. The chrome for my personal account [not the other two chromes] has text-enhanced ads in every site i go to. It double-underlines some keywords on every page. On mouse hover I get an ad overlay from http[colon][slash][slash]intext.nav-links.com[slash] Upon right-clicking one of the text-enhanced keywords and going to 'inspect element', i see that the text has been wrapped around with a CSS classname called adtext. It even shows the .adtext CSS descriptions on the right. How do i determine from WHICH particular extension is this CSS classname being injected into my pages?
