Okay, I am done with hover ads. I am so done with it, I am starting to avoid website which implement them even though I (used to) like those websites.

Obviously, it is considerably harder to block hover ads than it is to block pop-up or pop-under ads. As far as I know, AdBlock does not stop them, so then what?

My question is: how to avoid or block hover ads? Do you know of any tricks to do so?

I know it is debatable in how far it is fair to block ads in general and so lower the income the proprietor of a website will have from it, but I don't really want to have that discussion.

A lot of these ads offer the option to disable themselves. When you hover over a word and the ad appears llok and see if there's a question mark, or a link to settings. –  alex Oct 28 '09 at 9:31
Put that in an answer, dude, so I can give you creds for it. I have never noticed this and it is great! –  wzzrd Oct 28 '09 at 9:44
Call be paranoid, by I'm wary of clicking anywhere in a floating ad, at lease those on non "big name" sites. How do you know without reviewing the code that clicking the question mark or any other hot-spot won't instead open a series of pop-up/under windows or some such... Hence I used the aardvark option to remove the content while interacting with it as little as possible. –  David Spillett Oct 28 '09 at 13:25

In Firefox I have a filter in adblock plus of *.intellitxt.*

This seems to block them (or it blocks enough so that I have not noticed them).

If you are using Firefox, then the noscript add-on is an option. Most of these ads are loaded by script and noscript will block that. Though this will leave you with sites that depend on script for their basic purpose not working in other ways.

Another option (again Firefox only, though there are no doubt ways to do the same in other recent browsers) is aardvark which lets you manually remove the floaters. I find this handy for removing excess content when printing pages too. This is a manual process, but less of a blunt instrument than noscript. There are some places that are getting wise to such DOM manipulation though, specifically those hawking Microsoft's Silverlight - those floaters seem to detect that you have removed when and they replace themselves (as I've never come across anything on such an affected site that I can't get from many others I just add these sites to my "will never visit again" list, enforced by hosts file entry, and move on).

What you are looking for really is something that automatically does what can be done with aardvark without disabling all script. Unfortunately this is a significant problem as there are many ways to arrange floaters so such a tool would have to carry configuration for each site and would need to support a number of methods of removal, so would be much more of a chore to develop and maintain than noscript and aardvark. Writing something (an add-on or some sort of proxy based filter) to automatically detect and deal with floaters would require a level of AI not currently available (or, at least not currently remotely close to being practical to implement for this purpose!) as there are many ways to implement them and all could be mistake for more useful UI elements so false positives would be a noticeable problem.

You can remove or block hover ads with Aardvark and userContent.css

  1. Get Aardvark addon for Firefox or use it as as bookmarklet.
  2. Activate it.
  3. Identify the DIV, ID or CSS class of the hover ads passing the mouse over it.
  4. Apply a filter to block it in userContent.css file.

I also wrote up a blog post on this if you're interested.
