Is there a "CSS coverage" option in Firefox (or Developer Edition) ?
I'm looking for CSS Coverage in Firefox (Like it is in Google Chrome). I saw a YouTube video from a couple of years ago and there was a way to use CSS coverage at that time, but it looks like Firefox removed it... YouTube video: https://www.youtube.com/watch?v=Qrzf1lsBMMw
Mozilla says "This feature is experimental and is not yet available in Firefox", but I hope there is an option to use it in Developer Edition. (maybe we can activate it in about:config ?) https://developer.mozilla.org/en-US/docs/Tools/CSS_Coverage
Additional System Details
- Shockwave Flash 29.0 r0
- User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0
CSS Coverage was a GCLI command (csscoverage start|stop|report). The GCLI command line tool is no longer available (removed in Firefox 62). There is code in the current release, but I see nothing to start it.
I checked the csscoverage command in Firefox 60 ESR.
