Roundcube not sending email with brave browser

Hello,

  1. Do you have any other extensions installed/enabled? If so, does it still happen with them all disabled?
  2. Are you using ‘Secure DNS’ settings in Brave?
  3. Is anything set in brave://flags ? (Anything with a non-default setting will be sorted to the top, and will have a blue dot next to it.)
  4. What settings do you have in brave://adblock ?
  5. Does the issue occur if you create a new profile and try it in that profile?
