Faculty, have you ever “lost” annotations in a document you graded while using Firefox? This is an identified bug, but there is a work-around discussed below.
When an instructor uses Crocodoc annotations for a supported assignment submission type (primarily Word documents and PDFs), the Firefox browser frequently removes the last annotation when updating the score field in SpeedGrader. This behavior is a Crocodoc-specific limitation within Firefox that cannot be resolved by Crocodoc at this time. To warn about the effects of Firefox and Crocodoc annotations, Canvas displays a warning banner to faculty that says “Warning: Crocodoc has limitations when used in Firefox. Comments will not always be saved.” To avoid losing any annotations, instructors may choose to use another browser when providing Crocodoc annotated feedback, or click the screen to retain comments before navigating to another student.
