The Opera Desktop Team just announced a new experimental build of the desktop version of the Opera browser. The version that they are currently working on is 9.2 and when released it will have a few new features, including a usage report collection as mentioned a few weeks ago.
The new feature this week is a set of developer tools that will open in a pop-up window for the website that you are currently viewing. I tried it on our site to see how well it works and it is nicely laid out to help developers quickly troubleshoot problems. Here is a screenshot of what it looks like:
For my primary development tool I’m going to stick with Firebug right now because it seems to be more powerful and feature-packed. However, when designing sites I always ensure that they fully function with Opera and if I end up running into any problems this will definitely help. Thanks to the Opera Team for the nice addition!
