Connection Refused on Cốc Cốc browser [Browser is not supported]

edited July 2019 in Windows

I'm a new user to the chromium-based Cốc Cốc browser. I'm getting "Browser Connection Refused" error every time I open the browser. The extension seems to work fine on other browsers including Google Chrome.

Any ideas on how to solve this?

1Password Version: 7.3.684
Extension Version:
OS Version: Windows 10 version 1903 (OS Build 18362.30)
Sync Type: Dropbox

    Hi @HeRoKaNe,

    Thanks for taking time to email us!

    I am afraid Cốc Cốc browser is not one of the supported browsers, so you won't be able to use 1Password extension there. I would recommend you to use one of the supported browsers (Microsoft Edge, Firefox, Opera, Brave, Chrome) and install 1Password extension there.

    If you have any additional questions, we are ready to help. Thank you!
