I would like spelling to reflect American English not British English spelling.

When I use LibreOffice Writer, the spellchecker uses American English. However, when I am in Firefox, the spellchecker uses British English, i.e. favourite instead of favorite. Firefox used to spell according to American English. I would like to convert back to American English. Please tell me how to do this.

If you select a dictionary then Firefox should remember the choice and you should still have that dictionary selected on a next start

If you do not keep changes after a restart then see:

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Do you have the en-US dictionary installed and selected?

You can see which dictionary is selected if you right-click in a text area and open the Languages submenu.
At least one dictionary should be installed and have a check mark to indicate that it is selected.

  • Open the "Add Dictionaries" link to install a dictionary if you do not have one.
  • Make sure that [X] "Check Spelling" in the right-click context menu is check-marked.

You can also check the spellchecker.dictionary pref on the about:config page.

You can look here for dictionaries:

I clicked that it was useful to me. However, do I have to check this every time I go to write something or will it automatically correct to American English if I click it the one time?
