I managed to disable those annoying Flash banner ads in Chimera (I most often see them on Wired.com). Since you probably don't have one, create a file called userContent.css in your Chimera user chrome directory, which is located at ~/Library -> Application Support -> Chimera -> Profiles -> default -> random -> chrome. Replace 'random' with the name of the directory, which is usually a string of random characters followed by '.slt'. In the new userContent.css file, enter the following:
/* this hides the usual 468x60 Flash banner ads */Now restart Chimera and it should work.
embed[type="application/x-shockwave-flash"][width="468"][height="60"] {
display: none !important;
visibility: hidden !important;
}
/* this hides the not so usual but very annoying 728x90 Flash banner ads */
embed[type="application/x-shockwave-flash"][width="728"][height="90"] {
display: none !important;
visibility: hidden !important;
}
I (Rob again now) have shortened and slightly edited Dan's email; you can read the full text of the original post on his blog site. I tested this hint with Chimera and cnn.com, which runs a highly annoying vertical Flash ad down the side of the main page, and it worked perfectly! Thanks Dan!
