Neo Diggler is a Firefox Add-on that lets you define and run actions based on your current URL, like jumping to parent folders. It’s the successor of Diggler compatible with newer browser versions. It’s a very useful Add-on, I’d say. I’ll provide some actions I hacked together over the time. I guess there’s be much room for improvement, but they are indeed working real nice for me.
Reload the current page from CoralCDN.
Name: CoralCDN
Matching Regular Expression: ^http://(.+)$
Show Action as Menu Entry: no
Action: http://$h.nyud.net$p
Opens the BugMeNot entries for the current domain in another window. Doesn’t work in Windows.
Name: BugMeNot
Matching Regular Expression: ^(.+)$
Show Action as Menu Entry: no
Action: javascript:window.open("http://www.bugmenot.com/view/$h", "$h"); javascript:window.reload();
Loads the current page with an www subdomain (http://some.example.com/foobar.php becomes http://www.example.com/foobar.php).
Name: www Subdomain
Matching Regular Expression: ^(.+//)([\d\w]+\.|)(.+)$
Show Action as Menu Entry: yes
Action: $1www.$3
Loads the current page’s base address with a www subdomain (http://some.example.com/dig/around/here.html becomes http://www.example.com/).
Name: www Subdomain Index

Loads a current http page as https (ssl).

Click the left thumbnail to see how these actions appear in Neo Digglers context menu next to the Firefox address bar.
A great help when building Regular Expressions is KDE’s kregexpeditor, part of kdeutils. You can visually compose and analyse your regexes and match them against desired text.
And well, while this regex might seem like black magic at first (and second ;) sight, and it can be kind of mind boggling oftentimes, it’s really worth learning it! The syntax is being used in so many places (tools, programming languages) and will come very handy for parsing and substituting texts.
