Can't open links in emails when running Hiri as snap

If you're running Hiri snap package on Linux, with snapd version < 2.28.5, you might not be able to open links unless you install an additional package. To check which version of snapd you're running:

$ snap --version
snap 2.28.5
snapd 2.28.5
series 16
ubuntu 16.04
kernel 4.10.0-37-generic

You can fix this by installing the snapd-xdg-open package, e.g. on Ubuntu based distros:

sudo apt-get install snapd-xdg-open

However, if you're not running an Ubuntu-based distro, this package might not be available. In that case, it's best that you download and use the binary tarball.
