firefox - Firefox 何时为其主页截取网站屏幕截图？

Question

每当我获得声誉时，Firefox 就会理解并刷新我的缩略图。我想知道它是如何工作的以及 Firefox 何时为主页截取网站截图？

是否有任何meta标签或类似的东西来强制firefox截屏？

Answer 1

当你获得声誉时，Firefox 并不知道。 javascript 代码(当您加载页面时 stackoverflow 加载到 firefox 中)会执行此操作。如果您没有加载页面并且没有运行 JavaScript 代码，则不会看到任何变化。如果您想了解更多信息，请查阅 AJAX。

您可以强制更新图像，但这涉及加载页面。

Make Firefox create new images for the new tab page

The images will get re-stored as you use the new tab page to go to those websites again.

• Open the new tab page by clicking the + button on the tab strip.
• Click on one of the blank images to go to a website. Note, that it works only for left-click, opening in new tab doesn't do the trick.
• This is important - let the website finish loading (wait for the spinning green loading icon in the tab to stop).
• Open the new tab page again and you will see a new image for the website you just went to.
• Repeat this process for the rest of the missing images.
