Google introduced Chrome custom tabs five years ago, and most apps use them these days. Instead of creating their own custom browsers, developers can just hand over websites to a Chrome tab without the added bulk of a regular browser interface. The advantage is that devs don't have to spend resources on creating their own webview implementations and that users can quickly open these custom tabs in proper Chrome without reloading or losing their scroll position. It's a great system. But Google wouldn't be Google if it stuck with a great system (looking at you, YouTube Music). The company began experimenting with a custom browser for its Google Search app around six weeks ago, and it's now rolling out to more people. While it looks snazzy, it comes with more downsides than upsides.
