LO not finding its help files

[Pansmanser]

The last several times I have updated LO and have installed the GB language and help modules (from Download LibreOffice | LibreOffice - Free Office Suite - Based on OpenOffice - Compatible with Microsoft), the help files have not been available. Attempting to access local help returns a message such as
Firefox can’t find the file at /tmp/lu52542fadz9.tmp/NewHelp0.html.
The file does exist and attempting to open it directly produces the same message.
Assuming that is where the help files should be (which seems a bit strange) why is the help not opening correctly?
Ubuntu 22-04 LO 24.2.2

Can't get Offline Help to Work with Firefox

For full functionality you have to use the LibreOffice version shipped with your Ubuntu. Firefox not finding some file in the /tmp/ directory indicates that Firefox is installed from a flatpak package. These packages can not see the /tmp directory. I think, this can be configured somehow. For me flatpak is the reason why I drop Ubuntu after 10 years.

Thank you @fpy. I think you are right. I prefer not to use flatpak, but the other options have problems as well.
