JHU recommends using recent Chrome or Firefox with Canvas - https://canvas.jhu.edu/student-resources/canvas-faq-for-students/

Chrome and Firefox:

Sometimes you may click on eReserves or a title in the readings list and get a message that you need a new password. You don't! A refresh of the browser or clearing of the cache may help. If that does not work, try enabling third party cookies. See these instructions for Chrome and Firefox.

Safari:

Some versions of Safari present access problems in Canvas for the syllabus and eReserves.

Safari users can try enabling third party cookies. These instructions relate to Safari and Panopto (a video streamer), but should also work for problems related to syllabi and eReserves:

Please let librarydc@jh.edu know if you are having continued problems with access.
