Can Konqueror use user-specified stylesheets, like those in the Firefox adblock extention?
Yes, you can set Konqueror to use any kind of valid css stylesheet to filter webcontent or improve accessibility. From the Konqueror main window simply click Settings->Configure Konqueror… and select Stylesheets. Set the radio button to Use user-defined stylesheet and browse to where the stylesheet you want to use is located. Alternatively, you can select Use accessibility stylesheet defined in “Customize” tab and then set your own options. An example of css rules that implement ad blocking can be found at: http://www.mozilla.org/support/firefox/adblock.
