Hello, I have attached a link to a [http://i.imgur.com/Jxn87.png Screenshot] to help show what I am talking about. I have three problems in trying to get the layout the way I like it. Basically I am trying to get all toolbars in one row to maximize screen space and efficiency. 1: (Shown in blue on attachment) The navigation bar is excessively wide. In a previous answer somebody suggested editing the userChrome.css file, but I don't have any such file in my Mozilla Firefox program folder. 2: (Shown in orange on attachment) Even when I put all toolbars on one line there is a large space under my toolbars. FYI there are no objects (e.g. spaces) in this area when I go to "customize". 3: (Shown in red on attachment) I have 5 webpages that I want quick access to, next to the navigation bar. Firefox ends up showing 4 of these pages, then a drop down menu containing the one remaining page. If I delete one of these bookmarks it displays 3 pages and a drop down menu for one more, while the navigation bar grows to eat even more space (!!????). There is clearly enough room for all 5 pages next to the navigation bar if I could get this dropdown menu to disappear. Overall firefox seems to have done a good job at allowing the user to customize the toolbars but it seems there is work to be done. Thanks!
