How do I tell which font Chrome is using? [duplicate]

Question

Imagine I have the following CSS

font-family: 'Non-existant Sans', Arial, sans-serif; 

Assuming 'Non-existant Sans' is not installed on the system, Arial will be used by the browser. Using Chrome, is there any way of finding out which font is being rendered?

Edit: Dave (in the comments to the question) has pointed out a similar question. I'm specifically asking about Chrome here. Many of the answers in the other question suggest extensions which are okay, however; is there a native way of determining this information using the Dev Tools alone?

Edit Sept 2013: The Chrome team have just announced that font-family inspection is now available in the latest builds of Chrome Canary (Twitter link contains an image with more info). This should trickle down through dev > beta > stable over the next few weeks – great news!

Answer 1

In Google Chrome devtools in the 'Elements' tab, under 'Computed':

Answer 2

I'm a bit late to the party but I've just discovered a very simple way to debug which font your browser is using.

In the Chrome Web Inspector, go to the font stack in the CSS pane of the Elements Panel. Then, starting with the top of the stack, change the name of the font (I add random letters) while keeping an eye on the text in question. When you change the one in use you will see the text change font as it falls back to the next one in the stack.

I assume something similar is possible in most dev tools
