CORS request did not succeed

[Doubravka]

edit from @fonsp: we do not recommend disabling CORS security. This problem is caused by a content-blocking (privacy) extension, and is solved by whitelisting Pluto (e.g. localhost:1234) in the extension's settings.

Worked around by using "CORS everywhere" add-on in Firefox.

I've updated for the latest version and it still doesn't work without the "CORS everywhere" plugin.

What extensions do you have installed? Does it also not work in a New Private Window?

[Doubravka]

Yes, it works in a New Private Window.

What extensions do you have installed?

I had the same problem but it was fixed by disabling the DuckDuckGo Privacy Essentials add-on.

Can you report this error to the extension?

[fonsp]

This problem is caused by a content-blocking (privacy) extension, and is solved by whitelisting Pluto (e.g. localhost:1234) in the extension's settings.

Please also report this error to the browser extension, with enough requests they might want to whitelist Pluto by default.
