Hi, When i open firefox dev tool and hover on an html element , firefox will show a blue area to highlight that html element on the website but if i select ( click ) on another html element, the blue area will suddenly disappear and i have to move my mouse out and in the html element which i has just clicked to make the blue area appear back. I have try to clear all data and reinstall my firefox to the latest version ( 70.0.1 (64-bit) ) but it still the same. I have tested on some other browser like chrome, opera, edge chromium and they don't have this issue. Although it not a critical bug but still make a little uncomfortable for me and other people who heavily use firefox dev tool everyday. Does it have any setting in firefox dev tool to solve this issue ? If not , please consider to fix this :D Appreciate and thanks to firefox team, this is an awesome browser.
