At this time, inline comments made within the Mozilla Firefox browser are unable to be saved. If several comments are made simultaneously, the newest comment will disappear.
The current workaround for this issue is to make sure that your crocodoc "Comments and Markups" frame is opened and to write a comment and click anywhere inside the crocodoc frame. This will cause the comment to be saved and added to "Comments and Markups" list.
We apologize for this issue and appreciate your patience and understanding as we seek a permanent resolution.
