Hey, thanks for the report. This is a known limitation of Cursor’s built-in browser. It runs as a sandboxed Electron webview, which blocks window.open(). Google OAuth uses a popup-based flow, so after the consent screen nothing happens.

For now, the workaround is to open the localhost URL in a regular browser like Chrome, Safari, or Firefox. Google Sign-In should work right away.

I’ve passed this on to the team. There’s no ETA yet, but your report helps with prioritization.

Hello, this is not a workaround. Is there any workaround to be able to use this feature ?

Unfortunately, there aren’t any other options inside the built-in browser right now. The issue is that Google OAuth uses a popup window.open(), and the sandboxed Electron webview blocks it. This isn’t something you can fix with a setting, it needs changes to the browser tool itself.

It’s crazy that this is still not solved. Most of the B2B companies out there rely on Google login, and a large part of them as the primary login option. Right now I can’t even use cursor browser and its Design mode, due to this limitation. Such a shame
