新版火狐 拖 功能

Firefox 28 already? It’s been a full six weeks since Firefox 27 and Mozilla is back with a freshly-baked version. You can get it in one of three ways: Waiting for an auto-update; choosing About Firefox from the menu; or downloading the installer from Firefox.com.

Firefox 28已经？ 距Firefox 27和Mozilla刚推出新版本已经整整六个星期了。 您可以通过以下三种方式之一获得它：等待自动更新； 从菜单中选择关于Firefox ； 或从Firefox.com下载安装程序。

Again, there are few obvious features for end users but we developers are more fortunate…

同样，对于最终用户来说，几乎没有明显的功能，但是我们开发人员更幸运……

开发人员工具更新 (Developer Tool Updates)

I find myself using the built-in Developer Tools more often than Firebug. While Firebug still has the edge in most areas, it can’t beat the Mozilla tools for speed and quick inspections.

我发现自己比Firebug更频繁地使用内置的开发人员工具。 尽管Firebug在大多数领域仍具有优势，但它在速度和快速检查方面无法击败Mozilla工具。

Firefox 28 introduces a split console mode that allows you to use the DOM inspector, debugger, profiler etc., without having to switch back and forth to the console pane. You can see this by clicking the toggle split console icon in the top-right of the tool window.

Firefox 28引入了拆分控制台模式，该模式允许您使用DOM检查器，调试器，事件探查器等，而不必在控制台窗格之间来回切换。 您可以通过单击工具窗口右上方的切换拆分控制台图标来查看。

The inspector also lets you change CSS colors using a new color picker widget rather than typing hex codes.

检查器还允许您使用新的颜色选择器小部件来更改CSS颜色，而不用键入十六进制代码。

游戏手柄API (Gamepad API)

HTML5 games are becoming increasingly sophisticated, but keyboard, mouse, and touch are not always the best control mechanisms. The new Gamepad API defines a cross-browser interface for traditional game console controllers offering a collection of buttons and axes.

HTML5游戏正变得越来越复杂，但是键盘，鼠标和触摸并非总是最好的控制机制。 新的Gamepad API为传统游戏控制台控制器定义了一个跨浏览器界面，提供了按钮和轴的集合。

The Gamepad API appeared in Firefox 24 but had to be enabled by setting dom.gamepad.enabled to true in the about:config preferences. The API is enabled by default in Firefox 28 and is also implemented in Chrome with a slightly different set of features and a -webkit prefix.

Gamepad API出现在Firefox 24中，但必须通过在about:config首选项中将dom.gamepad.enabled设置为true来启用。 该API在Firefox 28中默认情况下处于启用状态，并且也在Chrome中以稍微不同的功能集和-webkit前缀实现。

It’s possibly a little early to use, but see Using the Gamepad API on MDN for more information.

使用它可能还为时过早 ，但是请参阅在MDN上使用Gamepad API以获得更多信息。

影片更新 (Video Updates)

A few updates have been made to Firefox’s video handling:

  支持并启用了WebVTT(Web视频文本轨道)。 这用于使用<track>标记显示文本轨道。 蒂芙尼·布朗(Tiffany B. Brown)的HTML5入门：多媒体专门为这一技术撰写了一章。

杂项更新 (Miscellaneous Updates)

放弃地铁模式 (Metro Mode Abandoned)

Finally, Mozilla has decided to abandon a Metro version of Firefox on Windows 8 and RT (I realize it’s not named Metro any longer, but I’m yet to meet anyone who doesn’t use that name!)

最终，Mozilla决定放弃Windows 8和RT上的Firefox的Metro版本(我意识到它不再命名为Metro了，但是我还没有遇到任何不使用该名称的人！)

The Metro version of Firefox has been in development for more than a year and had a greater emphasis on full-screen simplicity and touch controls. In a recent press release, the team’s leader, Jonathan Nightingale stated:

Metro版本的Firefox已经开发了一年多，并且更加注重全屏的简洁性和触摸控件。 在最近的新闻稿中 ，团队负责人乔纳森·南丁格尔(Jonathan Nightingale)说：

“In the months since, as the team built and tested and refined the product, we’ve been watching Metro’s adoption. From what we can see, it’s pretty flat. On any given day we have, for instance, millions of people testing pre-release versions of Firefox desktop, but we’ve never seen more than 1,000 active daily users in the Metro environment.

“在此后的几个月中，随着团队构建，测试和完善产品的过程，我们一直在关注Metro的采用。 从我们可以看到，它相当平坦。 例如，在任何一天，我们都有数百万人测试Firefox桌面的预发布版本，但是在Metro环境中，我们从未见过超过1000个每日活跃用户。

“This opens up the risk that Metro might take off tomorrow and we’d have to scramble to catch back up, but that’s a better risk for us to take than the real costs of investment in a platform our users have shown little sign of adopting.”

“这带来了Metro明天可能起飞的风险，我们必须争先恐后地追赶，但与我们对用户几乎没有迹象表明采用该平台的平台的实际投资成本相比，这是我们承担的更好风险。 。”

I’m not surprised. Firefox attracts power-users and developers who are more likely to use the standard Windows desktop than a full-screen app. It means Firefox will not be available to Windows RT users but the tablets are yet to make a significant dent on the market. RT users are left with a choice of Chrome 32+, which offers an unusual — if not bizarre — RT experience, and IE11 — a browser specifically designed for the Metro interface.

我不惊讶。 Firefox吸引了比全屏应用程序更可能使用标准Windows桌面的高级用户和开发人员。 这意味着Windows RT用户将无法使用Firefox，但平板电脑尚未在市场上占有重要地位。 RT用户可以选择Chrome 32+ ，它提供了不同寻常的RT体验(即使不是怪异的)和IE11(专为Metro界面设计的浏览器)。

Firefox may not receive the attention it once did, but Firefox 28 remains one of the best browsers money can’t buy (unless you paid Dell to install it!)

Firefox可能不会像以前那样受到关注，但是Firefox 28仍然是金钱无法买到的最好的浏览器之一(除非您付钱给Dell来安装它 ！)
