Because PyInstaller modifies the LD_LIBRARY_PATH environment variable
to make things work correctly on Linux, when we try to launch any
subprocess (such as the web browser), that modified variable gets
picked up as well, causing things to go south.
To work around this Linux-only problem, we have to:
1. Save the current value of LD_LIBRARY_PATH
2. Move the value of LD_LIBRARY_PATH_ORIG to LD_LIBRARY_PATH
3. Launch subprocess
4. Restore the saved LD_LIBRARY_PATH again

Because Linux distributions don't have an 'universal' path for the
system certificate store, bundling libssl built on distro A might not
work on distro B, because distros tend to change path to the
certificate store at build time.
This means that creating a PyInstaller package on Ubuntu will include
the libssl built there, and if you try to run this package on a
different distro (e.g. Arch Linux), any attempt to create an SSL
connection will fail, because Arch Linux has a different path for the
certificate store than Ubuntu.
This issue is usually worked around by bundling certificates with the
app (usually using certifi), and then pointing the SSL_CERT_FILE
environment to it.
However, truststore seems to be a better alternative, since it tries to
use the certificate store from the system instead.
The list of benefits are listed on the project's page on GitHub:

On Linux, pystray's icon.stop() currently doesn't work well with the
AppIndicator backend.
So, instead of destroying the icon when the user restores from tray
(only to later re-create it when the user minimizes to tray again), we
have the option to control the icon's visibility instead! Luckily, that
works on Windows too!
Note that for this change to work properly on Linux, we need to switch
to the master version of pystray, because we need this specific fix:
5943ed4e19
After pystray releases a version newer than 0.19.4, we can switch back.
