dude im not a noob i know about fullscreen lol thanks for trying to help anyway as i sed ive alredy tryed all the alt options that ppl talk about nothing shows up and its not the other options because i turned the toolbars off myself so it woudnt be because of a plugin because im running safe mode if any1 can actually help me without telling me that i might have it fullscreen or offering me advice i have already tryed then please help me but for now ill just use google chrome until someone can help me.. ffs u wud think mozzilla wud have a fix for stuff like this like a simple right click to access ur toolbars shame on them

Had you been clearer and more complete about what you had already tried, I would not have posted.

We never know the knowledge level of the users posting questions here, dude. because we can not read your mind.

I accidentally did the same thing as well, however, the easiest way to fix this is by doing the following: Press & hold down the "ALT" key as you use your keyboard to type in: V T M

If you try to use your mouse or touch-pad you will lose the view again; that's why you have to use the keyboard only, until you get the "Menu" view back. I really hope this helps anyone....or at the very least it's a better response than some of the rude and obnoxious responders mocking our intelligence for doing it in the first place.  :) Best wishes all... :)

You can also press the F10 key to make the menu bar appear and go to "View > Toolbar" to set which bars to show permanently.

Found the solution!!!

Right click on the toolbar, then go to Customize, then "Restore Default Set" And VOILA! It worked for me just now...

Hope it helps everyone!

Thanks! Here´s the solution everybody!!!! That was the words I needed. Easy and actually the answer that I think all of us having deleted the tool menu bar by ourself (accidently of course ;-) was looking for. And the solution that Monzilla Firefox "themself" put in to reset the tool bars if anything like this happen. Why is it soooo difficult just to write this little word (or number) F10 as a solution somewhere easy to find. Thank you again! Your a genius.

The Alt key is a standard way of showing a hidden Menu bar. Firefox and IE use the Alt key to temporarily display a hidden menu bar, and in Opera the Alt key activates the Opera button drop-down when the Menu bar is hidden.
