Happily I discovered this little gem today – Screengrab which can be added as a Firefox extension. Then full page screen grabs are only a mouse-click away. Handy! You can even do defined-area grabs quickly. I love it – fantastic tool – thanks to the author.

• Web Developer Toolbar – I’ve been using this for years and it has never let me down. It just keeps getting better. When you don’t feel like firing up Firebug this toolbar is a lifesaver.
• Firebug – The best we developer extension, bar none for Firefox. I’ve recently been doing a lot of CSS layout and I think I would have been committed to a mental institution without this.
• FireFTP – I only recently discovered this gem. It seems like decent, free FTP clients are as rare as hens teeth (recent releases of FileZilla are good though) and I discovered this not long after FF3 was released. Works flawlessly as a full-functional ftp client right in your browser – brilliant!
• ColdFire – As mentioned in my earlier post. Like a diamond in the rough, polished while I wasn’t looking.

The only other extension I use every day is FoxClocks – not strictly development related, but seeing as I am an Aussie living in the UK timezones and world clocks are important to me and I haven’t found a neater way yet of keeping track of the time back home. Regularly updated, it just keeps getting better. One of the best general purpose Firefox addins yet IMO.

If there are any other firefox extensions other ppl are using that you regard as indispensible, let me know!
