我正在尝试从 Twitter REST API 中提取图像并显示这些图像。
因此，我陷入了逻辑僵局，因为我的 PHP/HTML 代码未在本地主机 PHP 内置开发服务器的浏览器中显示图像。我更喜欢 Firefox，因为它是更安全（私密）的浏览器，因此我首先在 Firefox 中进行开发。
我认为图像不显示的问题可能是 Twitter 不允许热链接到其图像的问题，但是我刚刚在 Chrome 和 Internet Explorer 浏览器中测试了相同的代码（如下），并且所有图像都显示正常。
所以我的[更新]问题是：为什么这些图像没有出现在 Firefox 或 Firefox Developer Edition 浏览器中？ Twitter 显然不存在热链接到通过其 API 提取的图像的问题，正如图像在 Chrome 和 Internet Explorer 浏览器中显示良好所证明的那样。
谁有这个有趣问题的答案？
