When opening a web URL from an app Android never show you the address, only a choice of browsers or opens the default browser.
This app allows you to share the URL, so you can see what domain it is. You can install com.nightshadelabs.anotherbrowser to give an option to return to a browser option.
Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.Download F-Droid
