I’ve to work with what I got :P Either way even if I was doing jQuery or Vue (like I did in the past) I wouldn’t ever use Firefox because even without the Angular extension, just plain JS/CSS debugging I like Chromium dev tools more.
Besides the fact that my target users are always Chrome users and by using Firefox for development in the past I run into issues because specific features would work in Firefox but not on Chrome and vice-versa… or some piece of CSS rendered differently Chromium offers a level of polishness on small details that Firefox wasn’t ever close to. Firefox’s dev tools are always playing catch-up time to Chromium’s, that’s what I see.
Maybe I’m biased like you seem to be, but in the opposite way :P
