Modular software can be pain - you end up installing tons of add-opns. I recently configured a new desktop box and had to reconfigure Firefox. Here's the lsit of extensions I installed, I'd be interested in comments about better or missing add-ins

•  Adblock Plus
  This is a tricky one. I get content for free for looking at some ads. Might be a fair deal, but often it's too much. On some sites I allow ads, on others not.
• BetterPrivacy
  Prevent Flash Cookies from tracking me
• Brief
  An RSS/Atom/... Feed reader
• Certificate Patrol
  Notifies me when sites change their SSL certifactes, might prevent fraud.
• Change Rerer Button
  I don't like being tracked. At least not always
• CookieSafe
  Firefox's cookie handling is damn limited. With this add-in I can edit/delete single cookies way simpler and easily change the per site settings
• Firebug
  Good for fixing broken sites
• FoxyProxy Standard
  When switching between company VPN and my local net I need different proxy configuration. With this extension I don'T have to go through the settings
• Greasemonkey
  Improve websites according to my interest
• JSON View
  Renders json more nicely. Good when working with JSON-based protocols
• NoScript
  per-site configuration of javascript and stuff. Some websites have nice JS free versions.
• Open in Browser
  Adds a new option to the download dialog to open in Browser as web page or plain text. Useful for files a server sends with a "wrong" header.
• Tab Kit
  The wider the screen the more I want to have the tabs on the side. This add-in shows tabs in a sidebar with a tree structure and different colors and such
• Tamper Data
  Edit HTTP Request before the browser sends them, initially I've got this for security research, nowadays I use it to work-around issues in bad WEb-UIs
• User Agent Switcher
  Maybe switching the User agent every now and then makes tracking a bit harder, certainly it can be nice to get a different view. Many sites have a mobile version which is focussed on the content way mor than the regular site.
• Web Developer
  Nice tool for working with HTML stuff
  

Recently I improved my XUL and JavaScript skills and wrote a small XUL application. To browse some data from a database. While at it I tried to create a list with resizable columns. While trying to get some help one of the suggestions was not to use a tree instead of a listbox to show a list. But well, that didn't solve the issue, the next important thing is to add a splitter betwwen the column headers, but well that alone would be too easy: You also have to set the CSS class to tree-splitter... So that's what such a tree looks like:

Thanks to Arne and Uwe for answering my stupid questions
