R – How to disable Firefox’s addons Adblock Plus’s Tab on Sifr text in Firefox

It was some kind of CSS problem. Rolling the sifr css properties into my screen and print style sheets fixed the problem.

In this particular case, I fixed it by adding 1px padding around the element. The text was a link within an list-item. The sIFR was applied to the <li>. Adding 1px padding to the <a> fixed it.

Not sure if it is the proper way, but it works and I've got tons more work to do.
