Exit / Escape Full Screen Firefox?

How can I escape / exit full screen in Firefox?

My cat accidentally jumped on my keyboard and at that point Firefox browser was open. I have no idea which keys it stepped on, but my Firefox changed mode to full screen.

However, I managed to come out of the full screen mode of Firefox.

To exit full screen mode of Firefox, please press the “F11” (Function 11) key.

    to escape you just press the little icon the makes screens big or small – it’s the one in the top right between the ‘-‘ and the ‘x’ -I panicked and found it by chance!

    THANK YOU. This was very disorienting, especially since Steve Jobs already assigned other useless functions to the F11 key.

    Thank you. How do we resize the screen? Like in Chrome, there’s a zoom button. :/

    IF your function keys have other uses, hold the function button then hit F11. Funtion is the fn button located between ctrl and your windows key.

    to exit full screen, open a tab page. Right click on google, and select “open as regular tab.” This should stop the tab from opening in full screen every time.

    There are several icons on the tab page, select the google icon is what I meant to say. You can also right click and remove icons on this tab page.
