1/1/19 update fixed the pop-up window size, all is now working great! 12/16/18 latest update allows saving custom location; however, now the pop-up window size is incorrect, cutting off hi/lo temps at bottom, and part of "Wind" button on the right. Also, the weather status is not displayed on toolbar after restart of browser until clicking on icon.

This is almost prefect though I took an older version compatible with firefox v39
