Firefox add-ons

Question

What Firefox add-ons do you use that are useful for programmers?

Answer 1

Web Developer for web development. Scribefire if you're a blogger-progammer

Answer 2

I was learning DOM inspector, but I've switched to Firebug.

Answer 3

• +1 for LORI ("life-of-request-info"). It's a very convenient alternative for rough measurements of the load time of a particular web page -- the kind of thing that you might otherwise use an external stopwatch for.

• New Tab Homepage. Combined with a "speed dial"-type homepage (a personal, fast-loading page of links that you use frequently), helps you get where you're going faster when you open a new browser tab.

• LastTab. Changes the behavior of Ctrl+Tab to let you navigate back and forth between your most-recently-used tabs with repeated presses of Ctrl+Tab, the same way that Alt+Tab works in Windows. Also provides a nice view of all open tabs while Ctrl is still being held down for easy navigation. (The resultant behavior is very similar to the Ctrl+Tab behavior in recent releases of Visual Studio.)

Answer 4

Adding to everyones lists, Tamper Data is quite useful, lets you intercept requests and change the data in them. It can be used to bypass javascript validation and check whether the server side is doing its thing.

Answer 5

As far as web development, especially for javascript, I find Firebug to be invaluable. Web developer toolbar is also very useful.

Answer 6

I find Hackbar to be quite useful. Very useful if you want to edit the querystring part of the url, to test for vulnerabilities, or just general other types of testing where you might end up with complicated query string values.
