Help issue on recent Xubuntu releases (firefox snap)

[guiverc]

Not a serious issue, but not ideal

** Expected Result

Asking for app help will show help page in browser

** Actual Result

File not found

Firefox can’t find the file at /usr/share/sgt-puzzles/help/en/galaxies.html.

** Background

As reported on IRC (https://irclogs.ubuntu.com/2023/07/06/%23xubuntu.txt)

[22:20] Hi. I like to solve an apparent bug on help of SGT puzzles. Launch SGT puzzle, then launch any game. On menu Help > Help on , it opens a browser (firefox in my case) but shows "file not found" error and the path to html file. However, html files are actually there. I can view them with lynx for instance
[22:20] I use Xubuntu.
[22:21] frasson, this is probably due to firefox being a snap, which is constrained and can't access files outside

I can confirm this on my mantic system, with the following issue noted in firefox (snap)

This is a Ubuntu specific I too believe on modern Ubuntu releases where the default browser runs contained (snap package).

(filed here as launchpad indicated bugs are tracked here)

The firefox snap has full access to all system documentation under /usr/share/doc is there any specific reason why the sgt-launcher package does not put its documentation under the default FHS compliant path ?

The documentation in question actually belongs to the sgt-puzzles package.
