Firefox Add_ons Help Please

I recently downloaded and installed the U.S. English dictionary add on for Firefox. I can't seem to find access to it or mention of it anywhere on the computer. Am I missing something?

Did you restart Firefox after loading the Add-on?

On the top of your screen click Tools > Add-Ons

It should be in the window that pops up. Then click options to change the settings.

Or on the top of the screen right click an empty area then click Customize. There may be an Icon you can drag and place on the tool bar for easy access.

 

There are no options offered, no draggable link.
I see that the word above "draggable" is underlined in red now = maybe that is the extent of this dictionary = am thinking it is dynamic only, rather than being referenceable..... which is also an underlined word........Ahhh, just right clicked the underlined words = the dictionary menu popped up = Live, Learn, I guess.
Thanks for your help!

Right click was going to be my next suggestion. Glad you got it! :major
