I want to delete tool bars. How do I do it?
Solved! Go to Solution.
You can't remove the build-in toolbars (Menu, Navigation, Bookmarks), but you can hide them via View > Toolbars or Firefox > Options if the menu bar is hidden.
You can uninstall or disable extensions that have added toolbars.
You may also use full screen view.
Pressing the keyboard key F11 (you may sometimes need to wait a few seconds for it to complete the action) toggles the full screen view on and off, that may help.
That may be rather unususl, possibly other key combinations would act as an F11 on your system, but you may still use menu options:
Glad to hear you solved the problem.
I guess you had some extensions added that you may not have remembered, or were added unexpectedly by other software.
