拥有数百万活跃用户的Google Chrome浏览器在正式发布之前会通过对新功能和错误修复的严格测试。如果您想在标准Chrome(Chrome)用户之前试用这些功能和修复，您可以切换到Chrome浏览器(Chrome browser)的最先进版本(edge version)Google Chrome Canary。
Google Canary是Chrome 的四个发布(Chrome release)“渠道”之一，允许Chrome以较小的用户群测试这些功能，目标是可以报告错误和问题以帮助快速修复它们的开发人员和测试人员。如果您对Google Chrome Canary(Google Chrome Canary)感到好奇并想了解更多信息，以下是您需要了解的内容。
什么是 Google Chrome Canary？(What is Google Chrome Canary?)
过去，煤矿工人下矿时，会随身携带一只金丝雀作为预警系统。如果金丝雀幸存下来，空气就可以安全呼吸了。如果不是，是时候离开了。
“金丝雀”一词现在在技术界使用，指的是软件的 alpha 测试版本。谷歌浏览器(Google Chrome)也不例外，有四个不同的发布“渠道”，从稳定(Stable)版（为普通用户提供最稳定的版本）到金丝雀(Canary)版（提供前沿功能和修复，但不稳定程度更高）。
认识到这一点很重要，因为Google Chrome Canary 不是(Google Chrome Canary isn)稳定的浏览器。如果您决定使用它，请期待意外，从损坏的功能到定期崩溃。它可能看起来像Chrome，但在底层，测试了大量代码更改以帮助使Google Chrome 浏览器(Google Chrome browser)变得更好用。
Chrome Canary中的一些修复和新功能将通过发布渠道，在成为主要稳定版本的一部分之前，在Dev和Beta渠道中进行了彻底的测试。(Beta)但是，其他人将在没有通知的情况下被删除或更改。
Chrome Canary 适合哪些人群？(Who Is Chrome Canary Suitable For?)
Chrome Canary没有作为(Chrome Canary isn)Chrome用户的标准提供是有原因的，因为不稳定的浏览器可能会鼓励用户切换到另一个浏览器。它不适合大多数用户，他们不应该期望在日常使用中处理崩溃、减速、错误和其他问题。
Chrome Canary是开发人员、质量保证(quality assurance)测试人员和热衷于尝试最新功能和修复的好奇技术人员的测试平台浏览器。考虑到这一点，按预期使用 Canary：仅用于测试。例如(Don)，不要计划将它用于可能在随机崩溃(random crash)中丢失的关键任务工作。
如果您想尝试帮助Chrome 浏览器(Chrome browser)更好地使用，切换到Canary是最好的方法。如果您发现新的错误，或者如果您想提出新功能的建议，您可以使用Chromium 错误测试报告向导(Chromium bug testing report wizard)。
您还可以在Chrome 平台状态网站上查看(Chrome platform status website)Chrome Canary和其他Chrome 发布(Chrome release)渠道中的新功能或错误修复。
如何安装 Chrome 金丝雀(How to Install Chrome Canary)
如果您想在Windows PC、Mac或Android 智能手机上切换到(Android smartphone)Chrome Canary，则需要单独安装。作为单独安装，您可以在 PC、Mac或Android 智能手机上安装(Android smartphone)Chrome Canary ，而无需删除或替换稳定版Chrome。
- 要在 Windows 上执行此操作，请下载最新版本的 Chrome Canary(download the latest version of Chrome Canary)并运行安装。大多数 Windows 用户都希望安装 64 位版本，但32 位版本的 Chrome Canary(32-bit version of Chrome Canary)可用于较旧的 PC。Mac用户需要下载 Mac 版本(download the Mac version)，而 Android 用户需要从 Google Play 商店安装 Chrome Canary(install Chrome Canary from the Google Play Store)。
- 按照屏幕上的说明在您的平台上安装Chrome 。Windows 用户需要确认屏幕上的任何说明，而Mac用户需要将Chrome Canary 图标拖到(Chrome Canary icon )Finder 安装(Finder installation)窗口中的Applications 文件夹(Applications folder)中。
- 安装后，Chrome Canary将出现在Windows 开始菜单(Windows Start menu)或Mac上的Launchpad 菜单中(Launchpad menu)— 选择(Mac—select)此图标可在您的PC 或 Mac(PC or Mac)上启动它。Chrome Canary与稳定版的Google Chrome不同，它有一个金色图标，以区别于稳定版的Chrome 浏览器(Chrome browser)。

- Chrome Canary 窗口(Chrome Canary window)将打开，看起来很像Chrome的稳定版本，但有一些细微差别，具体取决于任何新功能。此时您可以开始测试浏览器。
与Chrome的稳定版一样，安装(Chrome)Canary后，您可以使用Google 帐户(Google account)同步书签(sync your bookmarks)，但您可能更愿意将帐户配置文件与可能存在错误的浏览器版本分开。如果您决定停止使用Google Chrome Canary，请以通常的方式卸载您设备上的浏览器。
在 Windows 上，您可以从Windows 设置(Windows Settings)菜单中卸载程序，而(uninstall programs)Mac用户可以从(Mac)Finder 应用程序的(Finder app)应用程序(Applications)文件夹中删除该应用程序。Android用户需要按住并选择应用抽屉(app drawer)中的Canary 图标(Canary icon)，然后选择卸载选项将其删除。
启用 Chrome Canary 标志和功能(Enabling Chrome Canary Flags and Features)
安装并打开浏览器后，并非所有Google Chrome Canary功能都可用。虽然许多新功能会自动激活，但其他功能需要您在浏览器中启用Chrome标志才能激活它们。
Chrome标志是Chrome 浏览器(Chrome browser)中的隐藏功能，除其他外，它允许您启用或禁用新功能。如果新功能非常新且特别不稳定，这些功能可能会在带有禁用标志的Chrome Canary 版本(Chrome Canary release)中提供，允许用户启用或禁用它们以进行测试。
- 要启用自定义设置标志，请打开一个新的Chrome Canary 浏览器(Chrome Canary browser)窗口。在地址栏中(address bar)，键入chrome://flags 以查看隐藏的标志菜单。
- 将加载Experiments菜单，列出许多您可以启用或禁用的标志。可用标志列在“可用(Available)”选项卡下，并简要说明了它们的使用以及它们是否会在未来的版本中保持可用。要启用或禁用标志，请选择标志旁边的下拉菜单，然后选择禁用(Disabled )或启用(Enabled)选项。
- 禁用某些标志需要重新启动Chrome Canary。为此，请选择窗口底部的重新启动按钮，或手动关闭并重新启动浏览器。(Relaunch)
- Chrome Canary(Chrome Canary)重新启动后，您可以测试新功能（如果可见）或在浏览器处于活动状态时监控浏览器的性能或稳定性(performance or stability)。如果您不满意，请重复上述步骤以返回“实验(Experiments)”菜单并从下拉菜单中将设置标志(setting flag)恢复为“默认”设置。(Default )或者，选择全部重置(Reset all )选项将所有标志重置为其默认设置(default setting)。
- Chrome Canary还有一个快速访问的Experiments标签，您可以查看它，让您快速启用或禁用主要功能测试。为此，请打开Canary 窗口(Canary window)，然后选择右上角的“实验”图标。(Experiments)从下拉菜单中，将一个或多个选项设置为Enabled、Disabled或Default，具体取决于您的首选。
测试更好的 Google Chrome 体验(Testing a Better Google Chrome Experience)
如果您想帮助Chromium 项目(Chromium project)并帮助Google Chrome和其他基于 Chrome 的浏览器变得更好，那么切换到Google Chrome Canary是一个很好的方法。通过测试新功能和报告错误，您可以帮助减少稳定版中的 Chrome 崩溃和死机(reduce Chrome crashes and freezes)。
如果Chrome Canary太不稳定，您可以通过其他方式尝试新的Chrome功能。例如，一些实验性的 Chrome 标志(experimental Chrome flags)可以在标准Chrome 稳定版(Chrome Stable release)中试用。或者，您可以安装新的 Chrome 扩展程序(install new Chrome extensions)，通过有趣或高效的插件扩展 Chrome 的功能。
What is Chrome Canary and Is It Safe?
With millions of active users, Google Chrome is a browser that goes through intense testing of new features and bug fixes before a general releаse. If you want to try out these features and fixes before standard Chrome users, you can switch to Google Chrome Canary, the cutting edge version of the Chrome browser.
Google Canary is one of four Chrome release “channels” that allow Chrome to test out these features with a smaller user base, aimed at developers and testers who can report on bugs and issues to help fix them quickly. If you’re curious about Google Chrome Canary and want to learn more, here’s what you’ll need to know.
What is Google Chrome Canary?
When coal miners used to head down the mines, they took with them a canary as an early-warning system. If the canary survived, the air was safe to breath. If it wasn’t, it was time to leave.
The term “canary” is now used in technology circles, referring to alpha test releases of software. Google Chrome is no different, with four different release “channels” that range from Stable, offering the most stable release for normal users, to Canary, offering bleeding edge features and fixes but with a lot more instability.
That’s important to recognize, as Google Chrome Canary isn’t a stable browser. If you decide to use it, expect the unexpected, from broken features to regular crashes. It may look like Chrome, but under the hood, numerous code changes are tested to help make the Google Chrome browser become better to use.
Some of the fixes and new features in Chrome Canary will make their way through the release channels, tested thoroughly in the Dev and Beta channels before becoming part of the main Stable release. Others, however, will be dropped or changed at next to no notice.
Who Is Chrome Canary Suitable For?
There’s a reason why Chrome Canary isn’t offered as standard for Chrome users, as an unstable browser is likely to encourage users to switch to another browser. It isn’t suitable for most users, who shouldn’t expect to deal with crashes, slowdowns, bugs, and other issues in day-to-day usage.
Chrome Canary is the testbed browser for developers, quality assurance testers, and curious techies who are keen to try out the newest features and fixes. With this in mind, use Canary as intended: for testing only. Don’t plan on using it for mission critical work that might be lost in a random crash, for instance.
If you want to try and help the Chrome browser become better to use, switching to Canary is the best way to do it. If you identify new bugs, or if you want to suggest new features, you can do so using the Chromium bug testing report wizard.
You can also check out new features or bug fixes in Chrome Canary and in the other Chrome release channels at the Chrome platform status website.
How to Install Chrome Canary
If you want to switch to Chrome Canary on your Windows PC, Mac, or Android smartphone, you’ll need to install it separately. As a separate installation, you can install Chrome Canary on your PC, Mac, or Android smartphone without removing or replacing the Stable version of Chrome.
- To do this on Windows, download the latest version of Chrome Canary and run the install. Most Windows users will want to install the 64-bit version, but a 32-bit version of Chrome Canary is available for older PCs. Mac users will need to download the Mac version, while Android users will need to install Chrome Canary from the Google Play Store.
- Follow the on-screen instructions for installing Chrome on your platform. Windows users will need to confirm any of the on-screen instructions, while Mac users will need to drag the Chrome Canary icon to the Applications folder in the Finder installation window.
- Once installed, Chrome Canary will appear in the Windows Start menu or the Launchpad menu on Mac—select this icon to launch it on your PC or Mac. Chrome Canary, unlike the Stable release of Google Chrome, has a gold icon to distinguish it from the Stable version of the Chrome browser.
- If you’re on Android, tap the Chrome Canary icon in your device’s app drawer. Like the desktop versions, Chrome Canary on Android has a gold icon—tap this to open it.
- The Chrome Canary window will open, looking a lot like the stable version of Chrome, but with some minor differences, depending on any new features. You can begin testing the browser at this point.
Like the Stable version of Chrome, you can sync your bookmarks using your Google account once Canary is installed, but you may prefer to keep your account profile separate from a likely buggy version of the browser. If you decide to stop using Google Chrome Canary, uninstall the browser on your device in the usual way.
On Windows, you can uninstall programs from the Windows Settings menu, while Mac users can remove the app from the Applications folder in the Finder app. Android users will need to hold and select the Canary icon in the app drawer, then select the uninstall option to remove it.
Enabling Chrome Canary Flags and Features
Not all Google Chrome Canary features are available as soon as you install and open the browser. While many new features are activated automatically, others require you to enable Chrome flags in your browser to activate them.
Chrome flags are hidden features in the Chrome browser that, among other things, allow you to enable or disable new features. If a new feature is very new and particularly unstable, these features may be shipped in a Chrome Canary release with a disabled flag, allowing a user to enable or disable them for testing.
- To enable a custom settings flag, open a new Chrome Canary browser window. From the address bar, type chrome://flags to view the hidden flags menu.
- The Experiments menu will load, listing a number of various flags you can enable or disable. Available flags are listed under the Available tab, with brief descriptions about their use and whether they’ll remain available in future releases. To enable or disable a flag, select the drop-down menu next to a flag and select the Disabled or Enabled option.
- Disabling certain flags will require Chrome Canary to restart. To do this, select the Relaunch button at the bottom of the window, or close and restart your browser manually.
- Once Chrome Canary restarts, you can test out the new feature (if it’s visible) or otherwise monitor the browser’s performance or stability while the browser is active. If you’re unhappy, repeat the steps above to return to the Experiments menu and restore the setting flag to the Default setting from the drop-down menu. Alternatively, select the Reset all option to reset all flags to their default setting.
- Chrome Canary also has a quick access Experiments tab that you can view, allowing you to quickly enable or disable major feature tests. To do this, open the Canary window, then select the Experiments icon in the top-right corner. From the drop-down menu, set one or more of the options to Enabled, Disabled or Default, depending on your preferred choice.
Testing a Better Google Chrome Experience
If you want to help the Chromium project and help Google Chrome and other Chrome-based browsers become even better, switching to Google Chrome Canary is a great way to do it. By testing new features and reporting bugs, you can help to reduce Chrome crashes and freezes in the Stable release.
If Chrome Canary is too unstable, there are other ways you can try out new Chrome features. For instance, some experimental Chrome flags are available to try in the standard Chrome Stable release. Alternatively, you could install new Chrome extensions to extend Chrome’s functionality with fun or productive add-ons.
