Some popular extensions add their own UI floating on top of normal webpages. This is as you would expect when that is what the extension does. However, you do not expect to see that on site's Speed Dial thumbnails. I'll show you how to prevent your extension from being displayed in Speed Dial thumbnails.

Status update on plug-ins (updated)

Saturday, December 17, 2011 12:06:13 AM

plug-ins

Many of our users on forums and elsewhere are echoing reports of issues with the Adobe Flash Player and some other plug-ins in Opera on Mac OS. Instead of continuing to answer in twenty different threads, I thought I’d sum up the issues in one place:

• Fixed in 11.60. Flash 11 causes a lot of crashes. Get the update. A restart may be required afterwards if the issue persist.
• Fixed in 11.61. Clicks are not registered in Flash in Opera 11.60 on Mac OS 10.5. We hope to address this in an update soon.
• Issues with streaming videos not starting in Silverlight. Update to Silverlight 5.
• Unresponsive and crashing plug-ins in general. The quality of plug-is on Mac are generally bad. There will be a major revamp of plug-ins (unstable preview release) that should prevent these issues from interrupting your browsing.
• Some older and unmaintained plug-ins (none of the popular ones) that use very old programming interfaces are unsupported since Opera 11.60.

Working with many third-party plug-ins is a complex issue. We hear your frustration. We hope that our continuous work on better plug-in support will result in great plug-in support on the Mac in the future!

In the meantime: update all of your plug-ins; disable unused plug-ins to improve start-up time, security, and stability; maybe even investigate alternatives to Flash. All of these suggestions should help brighten your day.

Multiple installations of Opera for Mac

Tuesday, November 1, 2011 3:13:42 PM

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:

YouTube WebM Plus extension for Opera updated

Tuesday, October 25, 2011 7:12:25 AM

extensions, youtube, plug-ins, WebM

I have forgot to mention that I posted an update to my YouTube WebM Plus extension for Opera. The extension that keeps you in the HTML5 Trial on YouTube to offer you plug-in free video playback.

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?

The next installment in the ongoing series of “where stuff are stored” covers Opera 11.50 and newer. All locations are as usual backed-up by the system-wide Time Machine service:

~/Library/Application Support/Opera/
~/Library/Opera/
~/Library/Preferences/com.operasoftware.Opera.plist

No longer showing XML parsing errors

Wednesday, September 28, 2011 12:11:00 PM

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.

Better than average network performance with HTML5 YouTube

Monday, September 26, 2011 4:27:51 PM

plug-ins, the-web, youtube

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!
