Via Tom, I found Jim Andertons blog, which mentions Venkman. It is a JavaScript debugger, that can be used to find those irritating small typos and bugs (not written by me of course ;-). It seems to be a jewel, and I will probably use it when I’m back from vacation!

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.
