So I don’t forget what extensions I am using in Firefox 1.5, here is the list:

• ShowIP - shows the IP of the current web site in the status bar
• MeasureIt - measure sizes and lengths using a rubberband
• Tabbrowser Preferences - some “must have” additions to tabbed browsing
• Disable Targets For Downloads - stop getting annoying empty tabs when downloading
• Web Developer - really useful stuff
• Console2 - great JS/CSS/XML error console
• Live HTTP Headers - to see what actually is sent to and from a server
• PDF Download - makes PDF documents more easy to download
• Extended Statusbar - more stuff in the statusbar, such as speed, percentage etc.
• SEOpen - search engine optimization
• unclosetab - I sometimes close the wrong tab

I tested Google Reader, but I think Bloglines is faster, easier and overall better.
