Comment 12 for bug 1026869

I have installed the en-us language pack in Firefox, and I've tried many of the "fixes" I found on the Internet, but this problem remains for me. For instance, "honor" is flagged but "honour" is not flagged. The "English (US) Language Pack" add-on is installed.

One interesting observation: when I go under Preferences->Language, I see that en-us is selected as the default. When I click on Set Alternatives, but the drop-down also shows en-gb and en-ca. I can click on Canada and UK and remove them, and they show as removed. However, after I restart, those two languages come back. So there appears to be no way to actually remove those languages.
