Firefox plugin for webscraping
Students here are often interested in how to efficiently collect information from the web. Here's a basic tool: iMacros is a plugin for the Firefox browser and lets you create macros to automate tasks or collect information. It exploits that all elements in html pages can be identified and hence targeted. For example a form field will have an ID that iMacros finds and fills with a value of your choice or click a specified button for you. Two nice features are that you can record your own macros without scripting, and that you can use the plugin to collect text information off the web. The capabilities are not what you would get from your customized Python script but it's easy to use and edit, and gets the basics done.
(The basic plugin is free but they also sell other editions with more capabilities.)
