Opera 12 supports Mozilla's "Do Not Track" header
This experimental build of Opera also includes optimisations to improve SSL handling and updates to XMLHttpRequest (XHR) that its developers say should "improve the upload experience on Google services (no more Flash uploaders on YouTube and Gmail)". More details about the development snapshot, including download links, can be found in the announcement blog post. Its developers advise users that the development release of Opera 12 may crash or lead to data loss situations, adding that "In fact, it may not work at all". The current stable version is Opera 11.61 from January.
