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. At least one dictionary should be installed and have a check mark to indicate that it is selected.

• 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 is check-marked.

You can enable or disable spell checking globally:

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

You can look here for dictionaries:

• https://addons.mozilla.org/firefox/language-tools/

English (UK) and English(US) dictionaries both installed and the Check my spelling as I type is ticked...

It seems to be Windows 8.1 that is blocking this. :o(

Does "Check Spelling" in the right-click context menu of the text area has a tick and is the correct dictionary selected in the Language menu?

Check Spelling does not appear on the right click menu.

I get:- Undo Cut Copy Paste Delete Select All Add Directories Inspect Element.

(I do get Check Spelling on the XP machine)

Is there something missing from the Registry?

Can you attach a screenshot that shows the code of the text area in the Inspector (click Inspect Element) to see if there is a spellcheck="false" attribute?

This will disable the Firefox spelling checker. In most cases the website has its own implementation to check the spelling, so look for a toolbar button in the editor.

there is no spellcheck=false attribute. Screen shot attached

That is a contenteditable div.

Try this extension:

• SpellcheckEverything: https://addons.mozilla.org/firefox/addon/spellcheckeverything/

Still the same .... no check as I type or any sort of spell check function.
