Editors’ Review

Download.com staffFebruary 29, 2024

The extension is actually a large collection of various tools for a Web master. Using Web Developer, you can get extensive information about page elements: link details, size, attributes, and colors. Web Developer can highlight any kind of elements (for instance, block-level ones and tables). You will even find a ruler utility to measure anything on a page. The add-on allows you to validate style sheets and HTML code of a page. Finally, you can use Web Developer to enhance the look of a poorly designed page. It lets you linearize a page, hide the background, and enforce large fonts. The extension installs a toolbar that accelerates access to the utilities. The extension will primarily interest Web masters but common surfers may use it for making pages more readable.

Cons
same as above
Summary
A useful tool.
pcpro17July 24, 2007
Pros
Firefox being the most W3C compliant browser out there, the developer toolbar enables development of CSS code without endless refreshing of the browser and the using up of bandwidth. I nice feature.
Cons
The thing is just plain useless if starting from code that is too non-compliant. It refuses to render any CSS in the browser window (while the debeloper bar is active), and no errors or prompts are generated as to give the developer a clue as to what is wrong.

One of my top 3 Firefox extensions

Pros
A must for web developers, information, image information, CSS and HTML editors, the list goes on! You have to try it to discover just how great it is. Even if your not a web developer it's handy as it has page info such as security certificates, links, forms and javascript errors! Resize your page, validate, view source, view cookies.
Cons
Nothing!

Pros
Of the programs I tested, Eusing found 1307 problematic registry entries, Super Utilities 1320, Registry Boost 288, and WinASO 1232. So it has a very thorough reg cleaner (but is not as good at telling the user why the entries need to be deleted, or sorting those entries out). I liked some of the add-ons like file analyzer, which is a very simple but clever and useful tool.
Cons
This program is like a swiss-army knife--it does a lot of things, but none of them as well as more dedicated application. There are more than a few features here which are simply rebranded standard windows utilities. I also didn't like the fact it tried to access the internet (caught by my firewall) without asking me immediately after I installed it. Seems like a rather high price for what it is offering.

It's a dyamo!

Pros
This tool is very useful for web development. The latest version actually include a Javascript console, so you can debug javascript. Wish it had a VBScript and PHP debugger.
Cons

Redirect your download

Pros
Haven't tried it yet but looks good! The link here just gives you a useless txt file, but I found the real deal here: <p>https://addons.mozilla.org/firefox/60/ <p>Hope this helps those of you who were victims of the same bad link I got!
Cons
Summary
Can't use it in it's present form!
ONEdererAugust 16, 2006
Pros
I can't tell what I like, it is currently not usable, with a ".txt" extension. Firefox will not pick up this program.
Cons
Unless there are instructions to tell us how to convert this downloadable program into a usable form, it is a wasted effort to download it. The ".txt" extension will not help us any.
Summary
wrong extensions
avouraAugust 16, 2006
Pros
NA
Cons
when I download the extension, it is the IE Tab 1.0.9 extension, which was already installed, but no sign of the web Developer extension at all. And the file downloaded with a .txt extension added to the filename, which was weird. When the link is fixed then maybe the extension will be available and I can review it properly then.
Summary
Gotta Have It
gnotellaluvrAugust 15, 2006
Pros
I love every aspect of this extension. I downloaded, but didn't really expect it to do much for me. Man was I wrong. This extension puts so many tools at your fingertips that it can be overwhelming at first, but you quickly get use to the power it and flexibility it gives as a developer. If you do web development on any basis, get this extension.
Cons
There is nothing to report here.
