The BEST! Rated 5 out of 5 stars

This is hands down the best FF add on out there for web developers. I use it every day, all day.

Fantastic Add-on, I've used it for quite a long time. One thing that I dislike is the old drop menu options. I don't us the toolbar for it, so I use the drop menu. However, I feel this is a little slow because it's just a bland, single column list with no icons to quickly identify the menu options so I tend to miss the one I'm looking for. Why not make it more like the Chrome edition, with the Firefox SDK it makes it easy to use "panels", so you can make the interface more Chrome-like using HTML files in the panel. Plus then it would be restart-less since it would be adding things programmatically, instead of through XUL overlays.

A must have for all web developers. Combine it with firebug and you have almost everything you need for front-end debugging

I learnt a lot with this tool. Very good to see a link hidden on a page with display link/view link information button.

While this is a great extension, it has some annoyances. Firstly, even though I opted for the toolbar to display "Text and Icons", it always reverts to showing Icons.
Secondly, I love the "Display window size in title" feature, but I have no idea how to disable it. Selecting the option again is not successful, and there is actually no indicator to show whether it's currently meant to be on or off.
If anyone is able to resolve these issues for me, I will raise my rating to 5 stars. Thanks in advance.

Huge problem Rated 1 out of 5 stars

In CSS panel, Ctrl-Z doesn't work anymore, if you :
Open the CSS editor.Make some change. At this stage, CTRL-Z is still working, till you don't click outside the panel.
Click anywhere on the page content.Click on the CSS editor tab, try a Undo, it doesn't work....

Neverending problems with that extension since the big 1.2.1 update.

This tool is fantastic for amateur web developers like myself. It allows me to find problems myself rather than referring every little issue to the extremely already busy dev team at my place of work.

Although I am yet to be able to fix the issues, I'm still learning, by being able to pin point them they can be fixed quicker. Very handy.
