¡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.

¡Gracias! Alex

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.
