Mozilla Rushing to Fix Firefox 3.5 Bugs
Mozilla will rush out a patch to its Firefox 3.5 browser to correct a number of bugs that users have cited as causing them issues. The patch, if it proceeds on schedule, will be released later in July.
The patched version will be named Firefox 3.5.1 and include a fix to the browser’s JavaScript engine, TraceMonkey, and another to how the browser runs in Windows XP. Mozilla has scheduled a Firefox BugDay for its community to tackle "major 3.5 bugs" on July 7.
According to the real-time counter on the Mozilla site, over 8 million copies of Firefox 3.5 have been downloaded worldwide since the browser’s general release on June 30. Mozilla had released Firefox 3.5 Beta 4 on April 27, allowing users to test-drive the new features, including support for JSON and Web worker threads.

The futility of chasing html 5 w/o video and audio codec std ?
Currently, Triple play is standardizing on Mpeg2 and Mpeg4(mjpeg). So, opera will eventually be obsoleted, from lack of media conformity.
Most computer people are not aware that media transmission must conform to broadcasting camera technology. Otherwise all the media formats need conversion and will be bugs galore.
Witness the many years of promoting Mpeg4 versions, now settling on Mjpeg, Dolby 5.1 and html4(Yahoo webpages). Its futile to offer more codecs to be converted and wasting realtime power and speed.
I believe that those groups chasing technology invented without hardware support will fail. That media generated by broadcasting cameras will end up the defecto standard.
Footnote:
Mjpeg is digital camera std. Mpeg4/h.264 is digital camcorder std. Mpeg2 with five layered video files are broadcastin camera std.
