Letting the browser do all the work is not a good option and should not be the only option to give our students. Not everyone uses Firefox even if it is the recommended browser.
Moodle really needs to clarify PSpell/ASpell/Google because not everyone knows that Google has been discontinued. It is still the default in Moodle but does not work. Many hours wasted trying to figure out why a Moodle feature it was not working only to find out it was Google.
Not happy! I am new to Moodle and took over when another guy left.
