Right a couples of minutes before to write this article I had an issue: how to go back to the default font size / page view in Firefox after I zoom in ( Ctrl + scroll down) and zoom out (Ctrl + scroll up) for a couple of times.
I really really screw up. My website was looking like a mess. But how to reset in Firefox the web page’s text size to default size? Not easy to solve the problem but after a while I figure it out what is the way you can do it.
You have to press CTRL + 0 (zero) and the page font size and the entire page view in Firefox is coming back to the original size. A great discovery for me and hopefully for you, too :)
