Some website contents seem not working on Opera. I tried to open for example:

1. https://canvas.cornell.edu/courses/1451/pages/reflect-what-kind-of-note-taking-works-for-you?module_item_id=28441

2. Online prep course (GRE or TOEFL) at ets.org.

Those websites work fine on other browsers like Chrome or Miscrosoft Edge.

Best regards

Morfield!
