The Internet Explorer Developer Toolbar, developed by Microsoft, offers several features and options to aid web development and design.

It shares many features that we love from Chris Pederick’s Firefox Web Developer extension such as: outline div elements, mark-up validation tools, ruler and measuring tools, resizing the browser window precisely (i.e. to 800×600), and all that good stuff.

It’s an essential tool for analyzing and troubleshooting web pages.

2. Web Accessibility Toolbar

The Web Accessibility Toolbar, developed by Vision Australia, was designed specifically to assess and analyze the accessibility of a web page, but it’s very useful regardless of whether you’re testing for accessibility or not.

Some features:

Some features:



4. WebCollect

IE still can’t match the Firefox’s number of extensions for web developers but these extensions help even out the field a little bit.

Got any interesting experiences with any of these tools (or horror stories)? Share it with us in the comment section.

The prospect of using IE again as part of my development environment just makes me cry, in the good way of course (like after sex or skydiving), I’m just so happy at the prospect of using IE again. I’m especially excited about the microsoft plugin which I’m certain just kicks firebugs a%#.

I’ve never used any of these tools but I certainly have my share of IE horror stories. One problem in particular comes to mind, after installing SP2 on XP my IE actually stopped working. Funny thing, a service pack actually breaking a application, just wonderful; but hey its microsoft I don’t expect anything they make to work without extra work.

FYI. My sarcastically expressed hatred of IE and microsoft shouldn’t be taken personally, I appreciate this blog and the valuable posts made here thats why I’m subscribed to the RSS feed.

Thanks for the list, so far I’ve only used the “Developer Toolbar” on IE6 once in a while hunting layout issues.
I hope the future will no longer be about a browser having all the developer tools (we all know FF has a good start and Safari also introduced some sort of web developer extension).

Eric Lawrence Apr 23 2008

Hey, thanks for the mention of Fiddler. Note that there are a few great add-ons available for Fiddler; check out

I’ve recently just made a decision to use nothing but Firefox from now on. This makes me regret my decision, because deep down I love IE7, and this might be a good enough reason for me to go back. Nice read.

what is wrong with you people? Firefox is one of the only browsers a real webdeveloper should be working with, you’re actually not even a developer if you work with IE!
creating plugins and addons for IE (with probally a load of spyware) is like putting a sticker on a wrecked car!
please i beg you, use Firefox with the correct extensions and develop like a man.

Lee G. May 15 2008

i agree with glenndavid… IE is out and firefox is in. even though IE7 has made massive improvements, I know if dev companies all around the world that only now only dev in FF. all hail the mighty firefox !

I recently ran across this web based application for building forms and search applications without programming. I was quite impressed with what Caspio Bridge can do. Go to

@glenndavid and @Lee G.

Considering that IE still has the largest market share, I wouldn’t trust any “real web developer” who doesn’t test in IE.

Thanks for the list

Use it Yet? Jun 14 2008

glenndavid, before you say that, have you ever infact use the ie developer toolbar yet?

i bet not. it really kick that little firebug ass.
i used firebug, and i try ie developer toolbar, and i will never switch back.
firebug just give me too much junk which can not even show me what and where is the source css files came from.

ie toolbar on the other hand, it simple and right to the point, it can even tell you what is the css source file name, where is it, and what are the other in there. it even offer some handy little tool like color picker, ruler….etc
if you want to do anything with css, this tool rock.

you probably not even know how to use that amazing tool, but you are already framing it!! make sure you use it first before you blasting at it.

I have used firebug for a while but was forced to use IE7, so i installed ie developer toolbar and it has NO chance against firebug!
There is also no good way to debug javascript in IE, i installed debugbar but it only crashed IE all the time.
It’s time you realize that IE sucks, why should you use a browser that can’t follow W3C:s recommendations?

Inspect in iframe Feb 04 2009

Do you know a tool which will be able to inspect DOM elements in iframes?

Jacob Gube Feb 04 2009

@Inspect in iframe: I haven’t tried using IE Developer Toolbar in a web page that has iframes, but I’m betting it can do it. If not, try to open the iframe in a new window, but that would probably defeat the purpose of what you’re trying to do – which is to see how your iframes work in a web page.

Daniel Lihaciu Feb 13 2009

It’s very useful that tools for me even if work with marmura. Thank-you

Hey guys,

Does anyone know of any tools where I can alter the CSS live in IE7? Similarly to what Firebug can do.

The IE developer toolbar only allows you to add CSS attributes from what I’ve found so far. Even that is cumbersome.

Lance Aug 28 2009

Internet Explorer is a joke and I hate the fact that I have to test sites on it at all, let alone develop specifically for it.

Microsoft and their unwillingness to follow standards will eventually get them into trouble. How many people are sick of having to recode something that works great in 4 different browsers but not in Micro$hite Explorer
