with these changes I can only print a page the print preview capability has been taken away I use it all the time when wanting to print something from a website

When I was in a website and I wanted to print a page there use to be in the upper left hand corner of my screen a tab that said 'FIREFOX', I could click on that tab and I had several options, one was 'print' and 'print preview'. I use the print preview button all the time to see what the page would look like when I was printing and how many pages there were. I could then choose to print all or some of an article and adjust it to what I wanted to print. I no longer have that tab in the upper right hand corner. Now in the upper right hand corner is a tab for 'open menu', however in that menu is only a 'print' button. There is no option for 'print preview' and therefore I cannot adjust what I want to print. I also could adjust the margins, etc. from a view tab, that too I cannot find. I really hope there options are still available and how do I find them, where are they located?
