Comment 4 for bug 1968548

Well, I personally think that $HOME/.cache isn't the right place to unpack temporary files, those should probably be unpacked somewhere under $TMPDIR by default. But that wouldn't really solve this bug, because the firefox snap, being strictly confined, would still be unable to read these files. And there might actually be a good reason for file-roller to unpack files under $HOME/.cache/ that I'm not aware of.

Thinking about it again, I'm not sure that the OpenFile method of the FileChooser portal would be of any help here. It's firefox that is sandboxed, not file-roller.
