Works great -- Validate Local HTML hangs now Rated 5 out of 5 stars

Love this toolbar and use it a lot, particularly to check Responsive Layouts and to validate code.

One thing .. starting recently, the Validate Local HTML tool just hangs -- the green bar keeps spinning and never resolves. (Validate Local CSS still works). Will there be an update for this?

Even so, I'm giving it 5 stars.

Reset / Cancel modifications needed Rated 4 out of 5 stars

It looks a great module no doubt about that, only flaw is that it needs a 'reset everything' / 'cancel modifications' button after changes have been made.

Even after having cleared firefox"s cache and everything, and removed/disabled this module, changes I made before were still active - for example disabled maximum font size' and enabled 'disabled pages' color' were still active, so everyhing I browsed after that had no colors, fonts setting problems and stuff like that. I think that it's not normal that once the module is disabled/removed (and cache is empty) that changes you made before are still active.

Everything sems back to normal (no 100% sure though), but WD should have done it by itself I think. I may have missed something but honesly I don't think so.

Most Definitely DOES work with SeaMonkey 2.31 Rated 5 out of 5 stars

And remains the champ. This belongs in everyone's tool chest for the quality of its forensics. Bravo again, Chris

Not Available for SeaMonkey 2.31 Rated 5 out of 5 stars

Life was good, Web Developer was great, then I upgraded to SM 2.31, and my life came apart.

What happened? Is there any hope for future compatibility?

Unhappy :(

Very helpful - even with Firefox Developer Edition Rated 5 out of 5 stars

Awesome add on! I use Firefox Developer Edition, and this still adds cool stuff!

I like how it has a conservative look - doesn't distract, but if you need it, the icons are easy to read.

The one feature I wish it had is a User Agent switcher. This developer makes one, but it would be nice if it was included here.

This is a must have for all developers. It has lots of great tools. I find the window resize and the ability to disable the cache by far the two greatest tools

Really useful if you do anything with CSS or HTML. Definitely one for your toolkit.
