How to make a form-filling google chrome extension

Question

I was wondering if anyone could provide me with some links to some tutorials or explain (with some example code), how I would go about making a simple google chrome extension (or in any programming language or browser if that is impossible), how I would make an extension that can visit a specific site, fill a login form on that site, click some links and then do the same sort of thing on the linked to site.

Thanks

Personally, I would not use a chrome extension, but maybe a perl script. There is an extension called WWW::Mechanize that is designed exactly to do this kind of stuff.

You can find plenty of tutorials and examples, just google it.

Edit in 2021: the above recommendation has become a bit outdated since 2013. For a more up-to-date take, I'd still recommend a scriptable headless browser instead of an extension for most automation tasks, but probably not WWW:Mechanize. There are good lists of options, such as this one.
