Due to bug 652494, test_add_remove_dictionaries.xul is failing with an caught JS exception:
spellchecker is null at chrome://mochitests/content/chrome/extensions/spellcheck/tests/chrome/test_add_remove_dictionaries.xul:22
Josh, do you know of somebody who can figure this out? Might not fit the good first bug bill, but somebody who knows are testing framework and js can give it a shot I believe. I would be happy to help.
