It’s been a while I’m using the firefox and I really like it. Especially the developer edition, full of useful tools and etc.
But I also came across with a strange thing (for me at least) which is in the “inspect element” area. For example - if you go to the http://getbootstrap.com/ site. And open up the inspect elements and select an area (a div for instance) and then in the style section (right part of the inspect elements bar) choosing the “toggle classes” button and then type a bootstrap class - for example the “bg-primary” which will coloring the background of an element. You will see then the result before you hit the enter. Most browsers will does it, except the firefox. In firefox you have to hit the enter to see the outcome.
I would very much appreciate it if someone could help me about this.
