I'm using Zimbra via a hosted service provider. I'm using Firefox 18.104.22.168
Whenever I try to select text and place my cursor into any text box, including the email address line, I cannot see it. It is there, and I can edit the text, but I cannot see it.
Also, I cannot select and copy text in the notes section of a calendar appt sent by someone else. I also wanted to invite others to that appt, but could neither add users nor could I copy all of the conference-call notes to another appt.
