Firefox on start up has just started to continuously open in full screen . I can tap the "full screen " icon on the navigation bar and then the page goes to a quarter of the desktop where I then maximise it and I'm back where I wanted to be. How to I get it to load normally on start up ?

Hi Barty1958,

You can hit F11 to bring Firefox out of Fullscreen mode. If you close Firefox while NOT in fullscreen mode by going to File > Exit it should remember this for the next time it starts. You might also want to check the shortcut that launches Firefox to be sure it doesn't have an extra parameter to always start in fullscreen.

Info is great. Thanks. I actually worked around it. In options - home page. I chose option " Use current page ". This managed to remember my home page in full screen on re-start.


Thanks for your support.
