Works for me on Chrome too, but not Brave (my browser of choice).
Are there any security concerns holding on to 1p 6.0 ? I notice the mobile app still sees updates, but could there be in theory an unpatched security hold in the desktop app ?
Yes but I don't want to use chrome, especially after they break ad blocking.
To answer your question about the security: I don't know. I don't audit it, and copying and pasting lets me not really have to worry about the security of the browser extension.
