firefox 什么时候为其主页拍摄网站屏幕截图？
When does firefox take website screen shot for its home page?
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，firefox什么时候对其主页进行网站截图？
是否有任何 meta 标签或类似的东西来强制 firefox 截屏？
当你获得声望时，firefox 不知道。 javascript 代码（加载页面时 Whosebug 加载到 firefox 中的代码）确实如此。如果您没有加载页面并且 javascript 代码 运行 将永远看不到任何变化。如果您想了解更多信息，请查找 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.
