Hello,
I can successfully authenticate with my Mozilla Account, but I cannot sign in to addons.mozilla.org.
After entering my password and verification code, Mozilla Accounts successfully redirects me back to addons.mozilla.org. The AMO authentication callback then returns the following response:
{“detail”:“You do not have permission to perform this action.”}
Callback endpoint:
/api/auth/authenticate-callback/
I have reproduced the issue with the same Mozilla Account using:
- Firefox on Windows 11
- Firefox private browsing mode
- Firefox Troubleshoot Mode
- Firefox on Android
- Via Browser on Android
- A home broadband connection
- A separate mobile data connection
Troubleshooting already completed:
- My primary Mozilla Account email address is verified
- I cleared site data and cookies for addons.mozilla.org and Mozilla Accounts
- I tested in a private browsing window
- I tested in Firefox Troubleshoot Mode
- I tested on different devices and browser engines
- I tested on different network connections
- I reset my Mozilla Account password as instructed by Mozilla Support
Resetting the password did not resolve the issue. Mozilla Account authentication succeeds, but the AMO callback still returns the same permission error.
A recent failed attempt occurred on July 26, 2026, at approximately 12:13 PM China Standard Time (UTC+8).
Mozilla Support reviewed ticket 446260 and directed me to the Add-ons community because the problem appears to be related to my AMO account.
Because the issue follows the same account across different browsers, devices, and networks, it appears to be an account-specific AMO permission or account-mapping problem.
Could an AMO administrator or staff member please check whether my account is blocked, disabled, or incorrectly mapped in the AMO user database?
I can provide my Mozilla Account email address and other identifying information privately to an authorized Mozilla staff member if required. I have intentionally omitted the OAuth authorization code, state parameter, cookies, and full email address from this public post.
Thank you.
