i had a box at the bottom right hand corner of computer home page that showed in blue squares when the page was loading and firefox changed my page and now it and the toolbar on the top with the house icon is also gone dont know how to get it back
In Firefox, click the "View" near the top of the screen then toolbars. Maybe you have something de-selected there.
If you click the bottom choice in the toolbars list, (Customize), you can add/remove items and also drag them around to where you want them to be located. (or you can click the "default" button and put it all back to new again)
