Jëkýll & Hyde is a powerful and useful toolbar and menu set for Opera, but its last version was designed over Opera 8, so it doesn't include support for some features introduced in version 9, such as Create search or Content Blocking, so when you install this toolbar yo lose this options.

I've made a modified version of Jëkýll & Hyde toolbar to include support to those features and some other improvements and fixes. Some of the changes included:

I know I've already criticized Internet Explorer because of its distinctive way to interpret standards. But then I found the bug-of-the-day issue which means that Internet Explorer will give you an unexpected behavior failing where other browsers get success, so you must waste even hours or sometimes days to guess that what's going wrong this time with Microsoft's most (in)famous product may be:

• If a JavaScript function modifies the src attribute in a <img> tag, but it doesn't do it at the end of the function, the loading of the image may be canceled.
• An <IMG> tag with id and name but without src (common case of an image that will be manipulated through JavaScript) causes to loss session variables unexpectedly.
• If you change a <div> visibility style from hidden to visible, sometimes this change is not applied to the child objects which should inherit this property.
• IE doesn't support position: fixed;.
• PNGs using an alpha channel for transparency show black background instead of transparency in IE.
• If you create an object with document.createElement() and then append it to content with appendChild() it won't be initialized, you should use innerHTML property or insertBefore() or similar.
• onmouseover event doesn't work over transparent backgrounds.

These are the most recent that I can't remember now, but any web developer can surely apport much more. Many of these bugs have been solved in Internet Explorer 7, but 5.5 and 6.0 are still the most used.

Update: Opera 9.50 seems to solve this problem. Check your version and update if needed.

After a serious vulnerability had been discovered in Acrobat Reader for PDF, one of the leading products from Adobe now becoming a standard, which affected all browsers now the online video format they are also trying to introduce as a standard doesn't work with some browsers. You can check that Flash plugin for Linux (it seems that also affects Windows) doesn't play FLV video with Opera (you can also find cases with Firefox or Konqueror). You can find many reports of many users with this problem, I also had my fight with it. Finally, Gentoo Bugzilla gave me the answer:

Opera has just announced through its desktop team the releasing of a new developing version for betatesting that includes a tool that makes reports about browser usage and configuration and without private information to send it anonymously to the company to improve the browser. Someone named this Opera 'Spyware', though it's a feature not present in official releases, which can be deactivated, you can read reports before sending it and the browser warns you about this the first time it's run.

Those are the results of running the Acid2 test against the most popular browsers.

The results are eloquent, but just in case, I'm going to clarify it: it should be a yellow smiley face over a white background that when you pass the mouse over or near the nose, it becomes blue.
