Impressed Rated 5 out of 5 stars

I've been using Firebug and Quirk SearchStatus for years now and I still like these two a lot.

However, I've started using this add-on yesterday and a whole new world of possibilities appeared; for a non-programmer who's still technical-minded and SEO oriented, this is exactly what I need right now.

My only downvote for Web Developer add-on (which could also be a fault on my part, since I've just discovered the add-on, thus won't be reflected in the stars given) is that my FF bar now looks like it's been hijacked by an ugly script, with icons everywhere. Hopefully that will be "fixed" not too long from now.

But lately not displaying Generated Code! Which is pity. Could anyone check out what is going on? When clicked, Generated Code displays only initial HTML. Thanks. DB

Great tool ! Rated 5 out of 5 stars

This is by far one of the best tool for web developers. It answers all our coding needs and make things much smoother for us.

Used to be one of the best Rated 3 out of 5 stars

It's an all time classics, one of the first developer extensions that were available for Firefox. But let's face it: when its author switched to Chrome it started its slow decline and as today it's just abandoned. Not only it hasn't received new features in years—as Firefox upgrades come in more and more features stop working and it's very unlikely that they'll ever get fixed. As far as I know, there isn't even an active channel to issue bug reports.

It used to be great but it's time to move on.

Please update it Rated 4 out of 5 stars

Youtube HTML5 video player troubles Rated 5 out of 5 stars

С недавних пор стало дико тормозить видео на ютубе (через HTML-player), если отключить это дополнение - тормоза пропадают.

В остальном - идеальное и очень нужное дополнение
