Just installed Brave on desktop (Windows) and can’t seem to be able to set up Lastpass:
In Settings > Security, under Passwords and forms, selected Lastpass and went straight to Preferences (the link right beneath the dropdown list).
Here’s what’s trying to open (but can’t):
Already tried the trick that seemed to work for the OP of this topic on pref’s not opening more than once: went to Extensions, disabled and then re-enabled the Lastpass extension.
But it didn’t make any difference in my case.
Note: Preferences for me didn’t even open once.
Brave version: 0.24.0
