Do you mean the menu bar with File, Edit, View, and so on?

To turn different bars on and off, you can use one of these methods to show the toolbar list and select the desired bars there:

• right-click (on Mac Ctrl+click) a blank spot on the tab bar (or the "+" button)
• (menu bar) View > Toolbars
  On Windows, tap the Alt key to activate the menu bar temporarily.
• in Customize mode > Show/Hide Toolbars (see: Customize Firefox controls, buttons and toolbars)

To turn on the Menu Bar, Bookmarks Toolbar, or other bars, click it on the list.

BLESS YOU, A THOUSAND BLESSING!! while I seldom even HAVE any BLANK spots on that bar, it was there, I rightclicked and VOILA!!! up comes the "toolbar" SELECTION menu and from there I chose the toolbar menu! Now, why does it get hidden to the rest of the OLD world of OLD people with OLD brains and OLD expectations of their computer pagetops? Can u please submit to your upper echelons that this is an excruciatingly painful issue when we have been looking at the DXMN TOOLBAR menu FOR THE LAST 40 YRS (or so), and suddenly it's not only gone, you don't even mention it...kinda like Trmps former bunch of wives....all those old kids, but only one young wife with her one son??? anyway; YOU SOLVED MY HORRIBLE, FRUSTRATING PROBLEM THAT i SEARCHED EVERYWHERE, READ ALL KINDS OF UNNECESSARY, UNSATISFYING STUFF THAT TOTALLY IGNORED THE GREAT BIG MAJOR DISAPPEARING ACT OF THE TOOLBAR MENU THAT HAS BEEN AT THE TOP OF OUR PAGES FOR THE LAST 20 OR SO YEARS!!! AND SUDDENLY GONE AND NOT MENTIONED....AT ALL....BY ANYONE ANYWHERE!!!? THANKS GUY JSCHER; YOU'RE A MAJOR IN MY PAGES, cuz u understood what I was asking even tho' I'm horribly old, I used to be a CRT Data Entry operateor, and when I learned to DATA Entry, we had IBM punch card machines bigger than industrial screw mchines!! So, I've been at this a long time and it's recently been going thru some ridiculous changes, like some people think just changing things, making them different, will get them out of the dilemma of real problems that need software solving & renovation; truly innovative thinking won't be helped by just losing things on the pages we're used to, after you taught us how to use what is here, now you throw it away and forget ab out it. Hope your bosses can understand we're constantly confused and getting us lost on these devices makes ppl less likely to buy more of them; we'll just go back to older stuff that was less complicated and we sort of knew how to work them, or at least they halfway worked for us. I like Mozilla Firefox, but this year, January; we got told that our windows or Chrome or everyone no longer considers Firefox/Mozilla to be safe and they wouldnt let me sign in to my firefox-based ISP for email (Centurylink/embarqmail.com) Check out why Centurylink no longer will support firefox. Did u know thhat? I hope it gets fixed cuz i hate chrome, I tried to delete it off my n ew pc last year, but it got messed up bad and my daughter said I had to have it, and she fixed it so chrome was limited, put in its place for me to use it, not it to use me. Shes USAF-intel ops, so she does this stuff all day. She had no problem with Firefox but doesnt use you , why? I don't know, do you? and thanks. I wil never hesitate to bring issues to your superior intellects again; I have been bringing Qs to MS and Windows Help places for years and never got answers....you guys heard & answered me in 5 mins or less!!! Feel free to anotate my answers and use them to promote your site. you are greatest!!!

Microsoft encourages hiding the menu bar as part of its "platform guidelines." Firefox 4 switched from the full menu bar to a little "Firefox" button, and then Firefox 29 switched to the icon of the 3 horizontal bars. Anyway, that's the "why."

I'm just a volunteer here. You can submit feedback on the following page: https://qsurvey.mozilla.com/s3/FirefoxInput/

Check out why Centurylink no longer will support firefox. Did u know thhat?

I'm not familiar with that decision. I think someone else mentioned some changes with CenturyLink mail (zmail?).
