Chrome has a useful feature in Inspector - when you add a class to an element using sidebar it shows you a list of defined css classes so you can be sure that you type the right one or can search through them if class names are structured. Also, by going through a list of suggestions it applies the class so you can see how the element would change before adding it
Is there a possibility of having this in Firefox? Styles tab already can autocomplete class names
Also, one thing I miss in Chrome’s implementation is fuzzy search - it doesn’t allow to skip characters in structured class names, so sometimes typing almost the whole class name is faster than scrolling to a suggestion
