Today Mozilla made Firefox 30 available, a relatively minor release after the massive redesign in version 29. According to the changelog, new features include VP9 video decoding, support for Opus in WebM, and horizontal volume control for HTML5 video and audio. Developers got support for multi-line flexboxes and hang reporting for background threads. There were also a number of security fixes. The Android version of Firefox received better support for native text selection, cutting, and copying, as well as predictive lookup for Awesomebar entries. The availability of Firefox 30 coincides with the launch of Firebug 2.0, which features an updated UI and a new debugging engine called JSD2. Significant new features include JavaScript syntax highlighting and de-minifying, improved code auto-complete, and the capability to hide or show individual Firebug panels.
