Why does Firefox , Thunderbird ignore my english US settings ?
Even tho I have english US as my default language, in word processing windows, and emails my spell check continues to show english british red underlining. I checked my settings, it does show english US. OS: Linux Mint 17

¡Hola Alex!
Please install the "English (US)" dictionary from https://addons.mozilla.org/en-US/firefox/language-tools/
Let us know if this answers your question.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
