GHC needs the following packages pre-installed:

sudo apt install gcc g++ build-essential curl libffi-dev zlib1g-dev libgmp-dev libgmp10 libncurses-dev libncurses5 libtinfo5

It might be a good idea to stick to ghcup as it lets us know whenever an upgrade is available. For example:

Firefox by default gets shipped with redudant spaces (at least for me). This hack removes the gaps between:

• the tab bar and the window edges
• pinned tabs and unpinned tabs

• Set toolkit.legacyUserProfileCustomizations.stylesheets to true in about:config.
• Create a folder named chrome inside the profile directory (find the Root Directory in about:profiles).
