Make Firefox Window View Full Screen In Mac

I phrased the title like that because I used all those words,

Make Firefox Window View Full Screen In Mac,

plus the word bigger in my search.  I found this link, which basically says make a book mark, put it in the bookmark bar up @ the top.  For location paste this in, (if it doesn't give you the option to edit location, right click, go to properties and voila put location in)

javascript:self.moveTo(0,0); self.resizeTo(screen.availWidth,screen.availHeight);

And put it all in ONE LINE, OK?  Oh and BTW I have a mac from 2005 and os 10.39 so I'm upgrading soon but that's what I'm running.  Newer firefox and os 10 versions may have this built in.

Click on the bookmark in the bookmark bar, the bookmark that you have hopefully named something like Firefox Big or something catchy like that, and you can live life normally again.

Stumbleupon, Digg, Del.icio.us and what I'm doing

For one thing I got rid of my google toolbar, sorry google, and delicious and all the rest, I installed bookmarklets which I admit I didn't know about since I just got back into the computer thing hot and heavy after several years absence. I was actually trying to figure out why firefox was using immense amounts of memory.
For another thing all my blogger friends!! WHEN you have a particularly good post I am submitting it to digg, del.icio.us, and stumbleupon. Not asking anyone to do the same for me but........no seriously we should use those tools more and even tweet about great articles, I don't always do that but I'm starting NOW. I've been stumbleing some etc. and am making a conscious effort to do so now.
Also since I can't put this plug in too many places, CHANGE your bookmarks to my NEW blog addresses and please change on your blog log if I'm so honored to be there?
Florence View is now Tresa's Blog and Animals that Give Pause is the same name just .com @ the end. Yes I own my own .com, LOL.
I need to get outside and get my fat lazy dog who is on my lap outside while it's not raining!!
