在内容脚本中检测隐身模式(Detect incognito mode in an content script)

在内容脚本中检测隐身模式(Detect incognito mode in an content script)

我正在编写Firefox WebExtension，我希望能够检测我的内容脚本是否以隐身/私密模式运行。 可能吗 ？

我已经尝试过这些解决方案

使用window.incognito但它未定义 使用browser.tabs.getCurrent()获取当前选项卡然后访问Tab.incognito但是browser.tabs未定义 使用extension.inIncognitoContext但未定义extension.inIncognitoContext extension 。

有没有其他方法来获取此信息？ 我正在运行Firefox 50.1.0，我的脚本作为内容脚本运行，我的清单具有以下权限：

"permissions": [ "webNavigation", "activeTab", "tabs", "<all_urls>" ]

I'm writing a Firefox WebExtension and i would like to be able to detect if my content scripts are running in incognito/private mode or not. Is it possible ?

I already tried those solutions:

Use window.incognito but it's undefined Get the current tab with browser.tabs.getCurrent() then access Tab.incognito but browser.tabs is undefined Use extension.inIncognitoContext but extension is not defined.

Is there another way to get this information ? I'm running Firefox 50.1.0, my script is running as a content script and my manifest has those permissions:

"permissions": [ "webNavigation", "activeTab", "tabs", "<all_urls>" ]

这方面的文档可能不会立即显而易见，但如果您使用browser或chrome将extension.inIncognitoContext前缀，它将起作用。

console.log(browser.extension.inIncognitoContext);

The documentation for this might not make this immediately obvious, but if you prefix extension.inIncognitoContext with browser or chrome it will work.

console.log(browser.extension.inIncognitoContext);
