Firefox add-ons

Question

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

Answer 1

FireFTP is good for grabbing/uploading any necessary files.

Answer 2

Fiddler is a really great debugging proxy. Think of it as a more powerful version of the "Net" panel in Firebug or the Live HTTP headers.

It used to be an IE-only extension, now it also has hooks into Firefox.

Answer 3

MeasureIt is an unnecessary extension to have if you install the Web Developer Toolbar. Web Developer Toolbar includes a ruler as one of its features. Under the "Miscellaneous" category for Web Developer click the option "Display Ruler" to use a ruler identical to the MeasureIt one.

That will allow you reduce the number of extensions needed by at least one.

Answer 4

For web developing I use the Web Developer Toolbar, CSS Viewer and MeasureIt.

But I'm really not one of those who has a thousand of extensions to do everything. I like to keep things simple.

EDIT: Thanks to Dan's answer I don't need MeasureIt anymore. Can't believe I've never seen that! I guess I'll just have to pay more atention to this WebDeveloper toolbar.

Answer 5

I use Web Developer, it's a real time saver.

Answer 6

The ones I have are...

• Y-SLow
• Live Headers
• Firebug
• Dom Inspector
