Working well for me, including my pile of extensions and a custom media-intensive application.

Been using this continuously since the koji build finished and have had no problems.

This fixes 1203913 for me and appears to work fine otherwise.

Been running this continuously since it hit koji with a fairly heavy usage profile (100+ tabs, 15 addons, youtube HTML5, multiple video tags, etc.) and haven't encountered any problems.

Developed some python code and did some git operations; works great for me.

Deployed across 150+ machines and it appears to both work fine and fix my issue (1063827).
