The best extention, I cant work without it

very nice

Wonderfull addon. Great to see update at 2020!

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.

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