I work as a core QA at Opera. Do you have examples of the javascript problems that you experienced? We rewrote the engine for 10.50 so it's possible that that has fixed the issues you saw. On the DOM side we are working hard with other vendors through W3C / WHATWG / etc. to make the web specs precise enough that we can all converge on the same behaviour. Any bugs that you report [1] would be much appreciated. [1] https://bugs.opera.com/wizard/ https://bugs.opera.com/wizard/
