Canadian Dictionary Crashes and No Plurals Rated 3 out of 5 stars

Flags all plurals as an error so each must be added to the dictionary. Does the same with words in past tense ending with ed.
Also causes Thunderbird to crash 100% of the time when exiting the program. Nothing is lost as you were closing the program normally anyway.

This review is for a previous version of the add-on (2.0.3).
