This is one of the first addon I install when reinstall FF. I'm very happy to see that the "View Javascript" function work fine again.

A few things weren't working in prior release. However, they've been fixed now. This Web Developer tool is essential for my work, I've been using it for several years (have lost count how many). It is very handy. I rely on it. Thanks to Chris for maintaining it.

So many things aren't working: Color Picker, Line Guides, Display Ruler, cookies aren't modified, among them - for both FF and Chrome :(

No other Firefox Add-on is used more by me.

I find it EXTREMELY intrusive to open the addon's homepage (release notes) out of the blue after an (apparently) automatic update! Especially since the known breach on the Chrome addon a couple of years ago.

The addon itself includes some nice features and shortcuts. Three stars off, solely for not being able to fully trust this addon while it requires a lot of permissions.

SEHR GUT

nice !

every web developer must download this add on...very cool add on...
