According to the Copyright Office:
At this point in the process of developing the Copyright Office’s system for online preregistration, it is not entirely clear whether the system will be compatible with web browsers other than Microsoft Internet Explorer versions 5.1 and higher. Filers of preregistration applications will be able to employ these Internet Explorer browsers successfully. Support for Netscape 7.2, Firefox 1.0.3, and Mozilla 1.7.7 is planned but will not be available when preregistration goes into effect. Present users of these browsers may experience problems when filing claims.
According to the website, the comment and 5 copies should be sent to:
Copyright GC/ I&R P.O. Box 70400 Southwest Station, Washington, DC 20024-0400
I won’t go as far as a “call to action”, since support “is planned”, though this is very concerning to Mac and Linux users in addition to all Firefox users. Let them know that everyone should be able to access the system, regardless of your computer or browser.
I’ll try and follow this, and post an update when more information is available.
