我试图从Twitter REST API中提取图片并显示这些图片。
我的PHPHTML代码在本地PHP内置开发服务器的浏览器中不能显示图片，这让我陷入了逻辑僵局。 我更喜欢Firefox，因为它是更安全的（私人）浏览器，所以我首先在Firefox中开发。
我以为图片不显示的问题可能是Twitter不允许热链接到他们的图片的问题，但是我刚刚在Chrome和Internet Explorer浏览器中测试了同样的代码（如下），所有的图片都显示正常。
所以我[更新]的问题是：为什么这些图片在Firefox或Firefox开发者版浏览器中都没有出现？ Twitter显然没有问题，因为通过他们的API提取的图片的热链接，在Chrome和Internet Explorer浏览器中都能正常显示。
谁有这个有趣问题的答案？

对于那些在类似的束缚：Firefox显然将域名pbs.twimg.com视为跟踪器，并阻止所有连接到这个子域。考虑在你的浏览器中禁用跟踪保护，或者实现一个服务器端的垫片来预加载图片。
