Description of problem: When typing text in a form field (text or textarea) on a web page, the spellcheck will mark American English words as misspelled. I go to about:config, search for dictionary, and change it from EN-MW to EN-US. The spellchecker is then correct. Then a day or two later, this happens again. Version-Release number of selected component (if applicable): firefox-43.0-1.fc22.x86_64 How reproducible: I'm not certain how to reproduce it, other than to keep using Firefox for a while until it happens again. Actual results: Dictionary is set to EN-MW without user input. Expected results: Dictionary remains set to EN-US. Additional info: I do not have Firefox Sync enabled. I believe it might be picking up something from the OS language, but I'm not positive. I've never seen this behavior on other OSes.
