Brave browser is based on Chromium browsers. So, in Brave, the chrome extensions (plugins) can be installed.

But sometimes, you might get this error while installing an extension:

“An error has occured” Access denied

or

“Failed – Forbidden”

You could try these steps to help fix this issue:

• Go to “About Brave” and check if Brave is updated to the latest version or not. If not, then update it. This is the most likely solution.

• In order to install extension, brave will redirect to URL:

“https://go-updater.brave.com/extensions?response=redirect&os=win&arch=x64”

So, it might also be a server issue from brave server. In this case just check in their community forums to see if everyone is facing same issue. This will usually be resolved by them in a day or so. For example, if their servers are undergoing maintenance etc. Or you can also check in github issues for the brave browser.

• If none of these have worked, it might be a windows permissions issue. Try running Brave as an Administrator once to see if it fixes things.
