An update on how to maintain multiple installations of Opera xx.xx and newer for Mac OS X. If you are not entirely confident in what you are doing, you should start by backing up your Opera profile. If you use Time Machine, you are already backed up. Lets dive into it:
Version 3.0 does a much better job of not flooding your cookiejar and destroying your PREF cookie on YouTube’s domains. It comes with an extension options page that let you do some new cool stuff including the addition of a download link beneath all WebM videos. There is also a new more aggressive mode that prevents plug-ins from playing back movies altogether.
Download the extension from the Opera extension gallery.
The extension source code is also on GitHub were I would welcome translations and other contributions.
By the by, do you see speed improvements with HTML5 on YouTube?
Following up to my article explaining the occasional ‘XML parsing failed’ error messages. Starting with today’s Opera Next release the error will be handled silently by reparsing the document as HTML. The user will no longer be shown an error and prompted to reparse as HTML. The error message will be printed to the error console instead.
This is a move from developer centric do-what-the-spec-says to what other browsers are doing by applying magic that fixes the problem for the end user. To be, this error seems like just one of those things that should be on by default in a separate Developer/Debug Mode in the browser.
As we no longer show the error, it also means that Opera will no longer be a fully valid XML parser.
Update: the ODIN blog has more information about this change.
Think YouTube does not care about HTML5? My YouTube network performance graph might just be indicating the opposite:
I have got a 126% increase above the global average video loading performance, and 90% increase above my ISP average. The data have been collected over 30 days since August 27. The results are from my MacBook Pro and Windows 7 PC. Neither has any plug-ins installed and are running Opera 12 (WebM and Ogg Theora codecs only).
Want to help the Web reach its full potential and be more open and inclusive? Join the YouTube HTML5 beta using the Opera browser! The only thing you will miss out on is videos that have overlaid ads. Videos embedded on third-party sites are included in the beta too!

Do you remember November 23, 2009? It was the day Opera Software said it would reinvent the Web and release version 10.10 featuring Opera Unite. Maybe Opera’s Segway-moment (we haven’t rearchitectured our cities nor the Web) was not that memorable; but the technology is still around. Since November 2009, I’ve used Opera Unite for a few scenarios and thought I would share the use cases with you.
I’m currently busy testing to make sure Opera behaves like a good Mac citizen on Mac OS 10.7 ‘Lion.’ We’re looking good in the current release, and we have some improvements on the way for a future release.
