My Favorite Firefox 12 Feature? View Source

Firefox 12  view source

From the ‘Little Things that Matter’ files:

The new Firefox 12 release is generating headlines for being the first have silent updates. As a Linux user though, that doesn’t interest me much, since Yum-Update and Apt-get are my installation/update methods of choice.

What does interest me personally about Firefox 12 is View Source. More specifically, the new numbered view source feature.

That’s right. After a 15 years+ of struggling to correlate view source/browser code with site development, we can now finally see what line we’re on — without the need to copy/paste into another tool.

Sure, it’s a simple thing, but it’s something that I’ve wanted for a long time. Modern websites have lots of code and being able to talk to someone about something on a specific line is a fantastic thing to have.

Now why did this take so long to land in the open source Firefox browser? It’s a question I asked Mozilla and this is what they told me:

“Recent re-writes and re-architecting made adding line numbers easier than it would have been in the past,” Kevin Dangoor, Product Manager, Developer Experience at Mozilla said.

I for one, am thankful for the addition. When combined with the other awesome developer tools now in Firefox, this is truly the icing on the cake.
