Firefox 87 with some nice changes

Firefox 87 was released with a new feature for everyone developing websites with light and dark modes.

Developers can now use the Page Inspector to simulate prefers-color-scheme media queries, without having to change the operating system to light or dark mode.

Small but nice improvement!

But I also like the change of the default behavior for the Referer header. The referrer header can give bloggers information about who links to their blog, but blogs are only a small part of the Internet and too often the feature is abused. By the way, on my blog the Referrer-Policy header is set not to send referrers.
