I found the solution on another forum.

1. Hover over 'Options' in the Firefox drop-down menu.

2. Move the cursor to the right and down until 'Add-on Bar' is highlighted.

3. Click to enable the Add-on Bar. The missing icons will magically reappear.

Click on the image below to see what the drop-down menu looks like.

I am using Windows Vista and do not have a Firefox drop down menu. I may have that on my laptop which uses Windows 7. Is that where you accessed the Firefox drop down menu? I tried disabling and enabling the add on, restarting as prompted, but that didn't work. Would love a suggestion.

If you have a Firefox icon on the top left corner, click on it and you'll see the Menu Bar. If you prefer to have the Menu Bar instead of the icon, you can do this:

View > Toolbars and CHECK the Menu Bar.

Once you have the Menu Bar, do this:

View > and CHECK the "Add-on Bar".

AMAZING!! Thank you. In Vista I went to "View" and then "Toolbars" and checked the option for "Add On Bar" and it appeared. Thank you so much. Our business relies in a great part on the weather . I'm asked at least once a day, sometimes 3 times a day, what the forecast is. You just saved me hours!!! Now if the weather would just go back to the way it was this past week over the weekend!!

Sunshine !!

You are welcome. And it's sunshine here too, in Texas.
