Not all locales come with a dictionary installed due to licensing reasons.
If you do not have the en-US locale then check that you have a dictionary installed (Tools > Add-ons > Extensions) and selected.

Do you have a dictionary installed and selected?
You can see which dictionary is selected if you right-click in a text area and open the Languages submenu.
You can open the "Add Dictionaries" link to install a dictionary if you do not have one.
Make sure that [X] "Check Spelling" in the right-click context menu has a tick.

You can enable or disable spell checking globally:

  • Tools > Options > Advanced : General: Browsing: "Check my spelling as I type"
