There is a good chance that you may be letting potential subscribers to your email list slip through your fingers. It has nothing to do with your copy writing skills or the way your squeeze pages look. It is because of the popularity that Firefox web browser has gained and one of it's most widely used add ons.

This may or may not effect you depending on which autoresponder you use and how you add your autoresponder code to your squeeze page. I use Aweber as do a great majority of the Internet marketers that I know. When you create a web form in Aweber you click on a link to get the html code to put on your site.

The page defaults to a "Javascript Snippet" which is recommended. The reason for this is because you can make changes to the form and you don't have to make any changes on your website. The other option is the "Raw HTML Version". This code is easily customizable. You can change the look and feel of the optin form to better match your website.

I think that most people go with the recommended "Javascript Snippet" which can be a very costly error. Let me explain why. Firefox has become very popular and I would say that it is more popular amongst Internet marketers than IE. The number 1 downloaded add on for Firefox is called "AdBlockPlus".

This cool little add on blocks all kinds of advertisements which slow down your browsing. It blocks banners as well as javascripts that power a lot of advertisements. It will also block out your opt in form. Your squeeze page will show up with everything except for the little boxes where people enter their name and email address.

When I discovered this little tidbit, I realized that I had lost hundreds of potential subscribers to my list. (Thanks go to Rodger Hyatt for pointing this out to me.) I have always used the javascript code for all of my squeeze pages. If you are too, you need to get off your butt and change them right now because you are losing subscribers.

I am curious to know how many of you have fallen into this trap. Please leave a comment and tell me about your experiences with this. Maybe I'm the only dummy who has been doing this.
