I really like Amazon. I shop there a lot, get most of my MP3 from them and I also own three Kindles.
But still, since over a year Amazon tries to sell me their credit card each and every time I view my shopping basket.
I was not able to figure out how to disable it, so I created a one line rule for Adblock Plus to get rid of this.
Just click the ABP symbol in Firefox, select Filter preferences, click on the Custom filters tab then click on Add filter group and name the new group (e.g. Amazon CC BS).
Next, click the button right from the new group and select Show/Hide filters if the filter panel is not visible. Click on the Add filter button and add the following rule:
The result should look something like this:
What this filter does is to block any HTML element with the class cbcc_column which is where this credit card ad is normally displayed.
The part before “##” tells ABP on which sites this filter should be active, in my case amazon.de. If you are using a different Amazon site, just replace amazon.de with the name of the Amazon site you are using.
