Fast Save extension to save pics and videos from Instagram also crashes browser.
I noticed these issues in Brave Beta started a few months ago, now in main Brave after latest update.
Latest update 1.70.119 fixed the problem. However Brave beta 1.71.95 also released today still crashes.
All issues for me on Brave and Brave Beta are fixed, except Cloudflare verification still loops endlessly on both browsers.
I found out that theme for chrome and youtube Picture darkmode extension was blocking me from connecting to my accounts and watch youtube.
