Spell-check borked in Firefox

[Shadrack]

Since Firefox 20.0, the integrated spell checker has not worked in the message area of the forum. Works in other areas (like the Topic Title). I swear it worked in Firefox 19.0. When I right-click the message area "Check Spelling" isn't an option anymore. No issues with other message areas on other forums.

Noticed the same thing for awhile now. ****es me off.

For as long as I can remember, mine would decide to disable itself for no reason, I would have to continuously enable UK spell check
