iMacros is a wonderful Firefox extension that allows us to do many things. Its advertised features include the following (from MozillaUpdate):
Form Filler on Steroids and Password Manager
iMacros for Firefox relieves the repetition of checking on the same
sites every day, remembering passwords, and filling out web forms.
iMacros is the only web form filler that can automatically fill web
forms that stretch over several pages. All information is stored in
human-readable, plain text files that can be easily edited. Passwords
are stored securely with 256-Bit AES encryption.
Web Automation
iMacros can also automate the download of pages (with or without
images), PDF documents, and all kinds of images or files. In the other
direction it can also automate the upload of data from a file to
websites. You can use variables inside the macros, and import data from
CSV files.
The recorded macros can be combined and controlled with Javascript, so even very complex tasks can be scripted.
Data extraction/Web Scraping/Web mining/Enterprise Data Mash-ups
Just the opposite of form filling. With the EXTRACT command you can
read data from a website and export it to CSV files. iMacros includes
full Unicode support and works with every language, including
multi-byte languages such as Chinese.
Web Testing
Web professionals use the iMacros add-on for functional, performace,
and regression testing of web applications. With the built-in STOPWATCH
command exact web page response times can be captured. iMacros also
includes support for many AJAX elements.
Besides that, I have a few ideas. One of them would be to use this macro for RSS Pinging. Just record a macro that consists of visiting each pinger's site. Then, whenever you publish a new item, just run the macro! Be careful, as whenever you run one of these macros, your browser tabs tend to be closed, and the pages change. The product comes with many test macros, which demonstrate the usefulness and power of the extension. To get it, click here.
