Brave won't download any files

No matter what I do, my my Dissenter browser (based on Brave) won’t download any files from the internet. It just keeps giving me the message ‘insufficient permissions’ on the icon showing the download down to the left. Also, when I try to play tracks from YouTube, I need to refresh the page several times before it finally works out. Could you please tell me what to do? Thank you so much in advance.

**Brave Version 1.5.114

Please reach out to Dissenter support team as Brave and Dissenter is two different browsers.
