In the menu, open Help -> LibreOffice Help Firefox opens and says "Firefox can’t find the file at /usr/share/libreoffice/help/index.html?Target=scalc/.uno:HelpIndex&Language=en- US&System=UNIX&Version=7.4." $ ls /usr/share/libreoffice/help/index.html /usr/share/libreoffice/help/index.html I'm guessing this is due to firefox being in a snap and not having normal file system access.
