After Firefox closes all the columns

Nothing left to close all the topics on Firefox...

The address bar of the favorites bar in the menu bar is missing ..

If you want to display it again, it will no longer work, because the right-click area has been disabled.

There is no way to enter the Web site. There is no solution to collect it online.

Check the installation directory of Firefox. The related configuration file is not found.

 

I suddenly thought of shortcuts, so I tried them one by one. When I found Alt + T (tools), the menu bar suddenly appeared !! Life Saving! Right-click the menu bar and the page is displayed ~~~

 

Firefox may not have thought of this small problem either ..
