Have you ever used Print on Google Maps earlier before ??

Yes, I have as recent as last week

I should provide more details, as of last week , I noticed that the Google Menu Bar had chanced colors (to Black). Also the address bar now has a blue search icon that appears to cover several icons.

Also in the past when one looked up directions there was a print link (Print) that is also gone, hence there is no way to print what I have looked up.

it seems like latest Google applications are not compatible with the latest versions of Firefox. So i guess you will need to use Google Apps on Google Chrome or other browsers.

Google Maps not being compatible with Firefox 4/5 is pure "steaming meadow muffins"!

@otissams,

I can see and use the Print button in Firefox 4 & 5 at Google Maps. No change with the addition of that black menu bar should have any affect on the page header which has the Print, Send, and Link buttons to the right of the Search Maps bar.

Try the Firefox SafeMode.
A troubleshooting mode, which disables most Add-ons.
(If you're not using it, switch to the Default Theme.)

1. You can open the Firefox 4/5/6/7 SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
2. Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.
   

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.

If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.
