The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Reset Firefox – easily fix most problems article.

Thank you for your suggestion. However, when I'd performed your suggested actions 1-4, inclusive, nowhere did I find a "Printer-s" icon, and this icon did not reappear on my M.Firefox tool bar.

Was this button added by an extension or do you mean the default Firefox Print toolbar button?

Question owner

Thanks I'm not sure what you mean "by extension". Also, I'm not familiar with "the default FFox Print toolbar button". Initially, I had no visible "Printer-s" icon on my MFFo'sx toolbar. I took madperson's suggested action (see correspondence, above), and was able to drag and drop this icon onto my toolbar. However, it disappeared after I messaged him "thank you", and my following iamjakumars' suggestion did not restore this icon.

Chosen Solution

You can find a Print button in the toolbar palette and drag the button on a toolbar.

Thanks, cor-el, That's what I did before. This time, the Print icon was once again on the palette. I dragged and dropped it to the toolbar. Hope it stays put this time!!
