The Secret Button to get 3 Panels of Developer Tools - HTML + CSS + WAY MORE!

[@LeLeTesoro]

Never would have noticed those little icons. I'm loving these videos!

[@kristianjavieraguirretorre4851]

I love you FireFox.

Great! Finally they are here, glad to see these new videos with that kind of information that was something I was looking for time ago.

[@codepearls]

there is also a selector highlighter button i.e like a check box "says: Highlight all elements matching this selector". Thanks Mozilla team.

could you make a video on dev tool grids?

[@iftakharhusan]

Why firefox still doesn't have a sources panel like chrome? That is very useful to have.

It's important to mention the version of Firefox you are using. Version 60 is an extended support release but doesn't have this feature.

Are you just using regular Firefox or the dev version in this video? I have moved to Firefox dev and really like it.

@@MozillaDeveloper Thanks Jen. I have been using the Flex/Grid stuff in Firefox Dev that seems to be better implemented, in my opinion, over standard FF. I haven't done the FF Beta yet, but so far I think I will stick with Dev. Thanks again for your input and clarification.

@@MozillaDeveloper What's with the title "Firefox Browser Developer"? This can be seen in the About dialog box of version 70 and a few versions back, as well as www.mozilla.org/en-US/firefox/developer/ in this point in time. Has Firefox Developer Edition been renamed to Firefox Browser Developer? I don't like this. Firefox is a browser? Really? No kidding? Browser Developer... oh you mean me? No, not really. I'm not a browser developer. I'm not sure where you're going with this. If the idea is to familiarize us with the new name and then eventually rename it, then I don't approve it.
