Help doesn't open the installed help files

[Robin Sheat]

Open, for example, libreoffice calc. 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.

I am also seeing this issue in a jammy Xorg session with
LibreOffice 7.3 and Firefox 107.0.1 (snap)
