download and installing of linguage pak for English US
I successful installed "Grammarly" on this computer but have problems to do the same on my HP lap-top with Windows 10. May be Firefox has a better solution than "Grammarly"?

Dictionaries for spell checking and Language Packs are available from this page:
https://addons.mozilla.org/firefox/language-tools/
Grammarly would add many, many other features beyond spell-checking. However, I probably can't explain why it doesn't work correctly on your Windows 10 system. Maybe check their website: https://support.grammarly.com/hc/

The normal Spell checker in Firefox uses Dictionaries. https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker#w_adding-dictionaries
Language Packs are for changing the language of the User Interface of Firefox and not for any Spell checker. https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack
