How to create plugins/addons for firefox, IE and chrome

Question

Hi

I need to create plug-ins/add-ons for IE, firefox and chrome browsers for the following requirement:

If the url requested is in a particular format/ matching a particular regex pattern, the plugin has to block the request and pop up and alert box.

I have searched a lot but did not find anything helpful. For IE, I think we can create BHO for this purpose. But is there a way to achieve this using javascript?

Thanks in advance.

Regards, Maggi

Unfortunately, IE's addon development is still very arcane compared to Firefox and Chrome for the behavior you're trying to accomplish. You'll have to develop a BHO for IE whereas both Firefox and Chrome use Javascript as their addon platform.
