Can you attach a screenshot? *https://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem *use a compressed image type like PNG or JPG to save the screenshot You can enter Full Screen mode (F11) if you want to hide the toolbars. Were you previously using userChrome.css ? *https://www.userchrome.org/what-is-userchrome-css.html You can check if you have an "Old Firefox Data" folder on the desktop in case the Refresh feature in Firefox has been used and a new profile has been created. *https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems *https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile

the new tab bar is above the address bar and I want either gone or moved onto the address bar. The tab bar takes up to much space. A screen shot does not include the address bar or tab bar.
