Broader Android Browser Support
If you were using an Android device you were recommended to use only the Firefox browser, but as of today that recommendation is removed. There are no browser restrictions now for Android devices.
The visible change is that Android browsers other than Firefox no longer display a warning at the top of each page explaining what wouldn't work. Under the hood the change is that the site no longer relies on so-called "shared workers," a thing that for some reason Google, the main developer of the Chromium project which is at the heart of the Chrome, Edge, and some other browsers, has so far decided to exclude from its Android browser. Firefox, on the other hand, isn't based on the Chromium project and has full support for shared workers on Android. Nevertheless, shared workers aren't the only way to get things done, and so now this site uses other browser abilities that are fully supported on Android.
