If they're not in 'Customization',   maybe you'd like to give this add-on a try :

https://addons.mozilla.org/en-US/firefox/addon/page-zoom-buttons/

That add on throws an error message and doesn't install.

Is this about the NoSquint Plus extension?

This extension is no longer working since it has been coded to stop 90 days after April 23.

With my Firefox updated to 54.0.1, it seems Nosquint plus no longer works. And I only see 53.1 for the latest Nosquint plus update.

That's weird.   Can't find anything about it in the reviews   -   try again, maybe   ?

How about to zoom in and out press the 'Ctrl' key and the plus and minus keys  ?

Fact remains that you lost the zoom feature, and I never asked : You lost that in the 3-bar menu  ? That shouldn't happen ........

You lost that in the 3-bar menu  ?

yes

I know how to zoom in and out by keys but I'm stumped on what has happened.

That makes two of us  ! I'll see if I can find out   ..... In the mean time :   would you try that add-on again   ? (if you haven't already)

Yay   ! Found ad add-on that should definately work :

As for the zoom feature in the 3-bar menu that has mysteriously disappeared :

Have you tried rebooting   ?

I tried rebooting, restoring defaults and a new profile. And combinations of those.

Looks like I'm doomed to use an add-on.

Did you click Restore Defaults in the Customize palette?

You can click the Restore Defaults in the Customize palette to restore the default toolbar layout.

That looks like a good add on and I installed it. I like the options but it too does not seem to have plus/minus buttons (?)

When you scroll down, you'll find :

The current zoom level can be changed by clicking on the   plus and minus buttons.
