Hi malware fighters,
For those that want to regulate ads and Flash etc. , and how these appear in the browser when a web page load into your Firefox or Flock, you can make up a personal userContent.css file and put it into the Chrome folder inside the Profile folder of your Firefox or Flock browser.
Here you can get a ready made one and instructions: http://www.floppymoose.com/
To get the content I want I use ABP, NoScript, userContent.css and to delete annoying things that appear on a web page I use the NukeAnything add-on, and to really get them off for good the R.I.P. add-on.
Use the browser the way I like it, that is a very important thing for me, also read:
