I would like to export my avast browser data to a browser called brave.
I can’t get the avast passwords extension to work with the brave browser.

AFAIK, Avast Passwords supports Chrome, Firefox, and Avast Secure Browser: https://support.avast.com/en-us/article/Use-Passwords & https://support.avast.com/en-ww/article/254/

Brave does not appear to be supported.

As for Exporting bookmarks from Avast Secure Browser, follow steps shown below in attached picture.
