Yahoo expands support for Opera 9

, , ,

Yahoo! just announced an update to their system of Graded Browser Support. This is the scheme where they classify browsers according to capabilities, age, user base.

  • A-Grade browsers get full support. Yahoo does extensive testing, and tries to make services work well in them.
  • C-Grade browsers are known to have problems, and get sent "lowest-common denominator" code. When last checked, the only C-Grade browser was IE 5.0.
  • X-Grade browsers are everything else. They get the same code as A-Grade browsers, but Yahoo doesn't do any testing on them.

A few months ago, they added Opera 9 on Windows XP to their A-Grade list (replacing Opera 8).

This time around, they've made several interesting changes:

  • Expanded A-list support for Opera 9 across all operating systems they support, including Mac OS and older Windows releases.
  • Added IE7 and Firefox 2 to the A-list.
  • Dropped IE 5.5 and Firefox 1.0 from A-list to X-list.
  • Dropped Netscape from A-list to X-list.

The first item is most significant for Opera users, because it brings Yahoo's official policy on Opera support up to the same level as their support for Firefox.

The new chart only shows A-grade browsers, so it's not clear whether IE 5.0 is still supported at C-grade level or dropped to X-grade like IE 5.5. This may reflect support at Microsoft, which maintains support for IE 5.0 on Windows 2000, but not IE 5.5. You can't even download IE 5.5 from Microsoft anymore. You can get IE 5.0 by installing Windows 2000, and you can update to IE6 or download the installer, but you can't update to or download IE 5.5.

The fact that they've dropped Netscape is interesting, and represents another nail in the coffin of the web's former dominant player. Of course, the real action moved from Netscape to Mozilla years ago.

Yahoo! ♥ Opera 9?

, ,

Yahoo! has just promoted Opera 9 an A-grade browser -- one that they test on and aim for full support. At the same time, they've dropped Opera 8 from the list.

Graded browser support basically means that instead of "yes" or "no," they have several levels of support. A-grade browsers are those that they develop for and do full testing on. C-grade browsers are known to have problems, and are given stripped-down code. Everything else is X-grade, which is assumed to be just as capable as an A-grade browser, but they don't do any testing on it.

As an example, Firefox is A-Grade, while SeaMonkey and Camino are X-grade. The browsers should be functionally identical as far as displaying web pages is concerned (well, mostly), so testing in Firefox results in pages that also work in other Gecko browsers.

Since Opera 9 has added quite a bit of scripting and DOM support, as well as features like rich text editing, perhaps we'll soon see full support for Opera on some of the more elaborate Yahoo! services.

The one drawback is that services built for and tested on Opera 9 may not always work on older versions, which they aren't testing. But hey, Opera 9 is a free upgrade, and the system requirements haven't increased as far as I've noticed.
