Video chat windows resizes Firefox browser window and all open tabs

Problem:

With Firefox, when the video chat window loads in a new tab, the entire browser window with other open tabs is also resized.

Solution:

Firefox allows you to choose to open a new page in a new tab or a new window from under Tools -> Options.  Under "Tabs" select to open new pages in a new window instead of a new tab.  Additionally, you may choose to copy the video chat URL from the chat window, and paste it into a new browser window that you may already have opened.
