Which menu was it on?

You could try checking the NoSquint options dialog. Usually a button is available here:

orange Firefox button or classic Tools menu > Add-ons

On the left side, click Extensions, then look for NoSquint.

If there is no option to add/remove a menu item, you might need to reset all your menus and toolbars, but go ahead and check options first.

It was on the 'regular' menu, right side, below 'bookmarks' - I believe it was just below the 'addons' and above the 'samfind' And, thanks for the hint in the addons, I had already done that several times.

I didn't have it enabled, but I see what you see (or should I say, I don't see what you don't see).

I don't know whether there is any way to add a menu item yourself. (The Menu Editor extension only mentions removing and rearranging.) Perhaps there is a way to let the author know you miss the menu item?

Meanwhile, on the classic menu bar, there still is a menu item:

View > Zoom > Zoom Settings (NoSquint)

You can access that by pressing Alt+v to display the classic view menu.

With the mouse, you also can use the magnifying glass icon on the Add-ons Bar, or move it to the main navigation toolbar.

Do you still see the NoSquint extension as installed and enabled in Firefox/Tools > Add-ons > Extensions ?

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is a compatibility update available.

I do not see a 'tools' menu. Addons show no-squint, and I was able to enable no-squint in the bottom addon bar. All options seem to be fine, except cannot display in the firefox drop down menu as before. I guess I will just live with the bottom addon bar....... Thanks!

Did you look in the Zoom menu (press F10 to make the menu bar appear)?

I had totally forgotten the - & + adjustments on the toolbar! I am also able to <ctrl> wheel to adjust. I guess I really don't need to be able to access the settings for individual sites that badly. Thanks to all who have lent me a hand and tried to help. God Bless You All!

I don't normally use the menu bars - my eyesight is not too good, so I eliminate unnecessary bars. It is there though, thank you. However, pressing f10 does not toggle it..... Thanks

You can use this extension to adjust the font size for the user interface:
