firefox-2.0 alpha 1

在维道看到此消息，没啥说的，立刻下载使用，谁叫咱是做网页的呢。

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20060321 Firefox/2.0a1

我能看到的变化是：

1.每个tab 标签右侧，独立的关闭按钮（类似于 opera或者 firefox+tab mix 插件）

2.session saver （似乎从 1.6x nightly build 某个版本就开始支持）

Bon Echo will retain all of the existing Firefox features, with improvements that:

* update the look and feel of the browser,

* improve and augment the capabilities for Bookmarks and History,

* improve the user experience of web browsing and tabbed browsing,

* improve and augment the capabilities for handling web feeds,

* improve the user experience of adding, removing and managing extensions,

* add new capabilities to protect users from dangerous extensions,

* improve and augment the capabilities for web search,

* make it easier to install and distribute the browser,

* include the latest security and stability updates,

* include new security features to protect users from phishing,

* update our end user documentation so it’s more useful to users looking for help

Geir Ivarsoy, the co-founder of Opera Software, passed away after a long battle with cancer.

Geir along with Jon von Tetzchner developed the Opera browser, initially known as MultiTorg Opera, while working for a Norwegian Telecommunication company in 1993. In 1995 the two of them spun off their project and founded Opera Software.

At a board meeting in January of 2004, Geir (together with von Tetzchner) announced his wish to resign as a board member in Opera Software, though he remained active in the company even after that. In June of 05 he was elected as a member of the Nomination Committee of the company.

He passed away on March 9th; Opera employees will pay their respects to Geir at his funeral today at Grefsen Kirke in Oslo.

My condolences go out to his family, friends, and colleagues at Opera.

RIP Geir Ivarsoy.
