CORS bug in Vivaldi? Cannot access AWS S3 Console

kivagant

Hi.

I'm not sure if you can help me with that, but I'll try anyway. I cannot access AWS S3 console anymore with Vivaldi. It works well in Chrome, but in Vivaldi I'm getting many CORS errors like in the example:

POST https://us-east-1.console.aws.amazon.com/s3/proxy net::ERR_FAILED 400

Access to XMLHttpRequest at 'https://us-east-1.console.aws.amazon.com/s3/proxy' from origin 'https://s3.console.aws.amazon.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Request headers have these lines:

:authority: eu-west-1.console.aws.amazon.com
:method: POST
:path: /s3/proxy
:scheme: https
accept: */*
...
origin: https://s3.console.aws.amazon.com
referer: https://s3.console.aws.amazon.com/s3/buckets?region=us-east-1

Response headers from the request have:

access-control-allow-credentials: true
access-control-allow-origin: https://s3.console.aws.amazon.com
access-control-expose-headers: x-amz-restore-request-date,x-amz-checksum-sha256,Access-Control-Allow-Origin,x-amz-server-side-encryption-aws-kms-key-id,x-amz-server-side-encryption,x-amz-server-side-encryption-bucket-key-enabled,x-amz-tagging-count,x-amz-checksum-sha1,x-amz-restore,Access-Control-Allow-Credentials,Content-Length,x-amz-restore-expiry-days,x-amz-checksum-crc32c,Content-Type,x-amz-s3-console-op-id,x-amz-checksum-crc32,x-amz-checksum-algorithm,x-amz-restore-tier,s3v3,x-amz-bucket-region,Date,x-amz-s3-console-response-md5,Content-MD5,x-amz-replication-status,x-amz-expiration,ETag,x-amz-archive-status,Expires,x-amz-request-id,x-amz-id-2,x-amz-s3-console-request-id

As you may see, the access-control-allow-origin is there.

Any reason you are using an older version of Vivaldi?

@Chas4 , why an older? Current version is 5.3.2679.51, it's auto-updating. The problem is still there, though.

@kivagant I asked because the UA string was listing Vivaldi 5.1 there
