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.
• 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/

ok - it works now. Except that I was using the Australian dictionary - and that is no longer available. Which is probably why it stopped working.

Thanks

You're welcome

You will have to override the compatibility check if you want to use the Australian dictionary in Firefox 5.
