I have updated the browser today (Jun 18, 2020) and I cannot use it anymore: it is crashing after being open for a minute, even with all the tabs closed.
Tried to reinstall, cleanup the application cache (“Library” on MacOs).
I have to use FF instead, for now. It is a little bit painful.
There is something disturbing in the ‘Brave-Browser’ folder located inside the ‘Library -> Application Support -> BraveSoftware’. If you put it on your desktop (don’t throw it away) Brave will no longer closes. You can recover the bookmarks file located in the folder ‘Brave-Browser -> Default’.
Of course you will have to adjust your preferences and settings again and also download the extensions again (Hoping that the problem isn’t caused by one of these).
I hope it can help you.
