Keep the same instance of firefox running 2. Browse the web and use the computer as normal for several days 3. Resize the window Actual Results: Text and some parts of the browser no longer display properly. Expected Results: The text should wordwrap, or at least offer a scroll bar at the bottom of the screen. Additionally, tab elements should never disappear or become otherwise inaccessible. I am using the default theme.
Created attachment 282964 [details] Firefox window in a state where the error is clearly visible Note that the text isn't displaying properly, and that all of the tool bars, with the exception of the bookmarks folders still displays incorrectly.
