I cannot access my mail...only works offline

My zoho mail will not go online.  I can access the internet but not my mail.  I am receiving a script error and css errors.

My error console reports:

Warning: Expected ',' or '{' but found 'html'.  Ruleset ignored due to bad selector.
Source File: http://mail.zoho.com/mail/styles/main.css
Line: 250

And

Warning: Error in parsing value for 'filter'.  Declaration dropped.
Source File: http://mail.zoho.com/mail/styles/main.css
Line: 263

and

Warning: Unknown property '-moz-opacity'.  Declaration dropped.

Anyone know how to fix this??
