download and install latest geckodriver for linux or mac (selenium webdriver)

geckodriver-install.sh

#!/bin/bash
# download and install latest geckodriver for linux or mac.
# required for selenium to drive a firefox browser.

install_dir="/usr/local/bin"
json=$(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest)
if [[ $(uname) == "Darwin" ]]; then
    url=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("macos"))')
elif [[ $(uname) == "Linux" ]]; then
    url=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("linux64"))')
else
    echo "can't determine OS"
    exit 1
fi
curl -s -L "$url" | tar -xz
chmod +x geckodriver
sudo mv geckodriver "$install_dir"
echo "installed geckodriver binary in $install_dir"

Install using brew or apt-get - https://gist.github.com/MichaelCurrin/b8f616b3182ea98ef88c3042b988402c

A different version of the script modification provided by @brunoao86, that I use is to utilize jq further and dropping the asc urls right in the search. See below for the full script

#!/bin/bash
# download and install latest geckodriver for linux or mac.
# required for selenium to drive a firefox browser.

install_dir="/usr/local/bin"
json=$(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest)
if [[ $(uname) == "Darwin" ]]; then
    url=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("macos")) | select(contains("asc") | not)')
elif [[ $(uname) == "Linux" ]]; then
    url=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("linux64")) | select(contains("asc") | not)')
else
    echo "can't determine OS"
    exit 1
fi
curl -s -L "$url" | tar -xz
chmod +x geckodriver
sudo mv geckodriver "$install_dir"
echo "installed geckodriver binary in $install_dir"

Will the latest version of geckodriver driver work with the latest version of firefox-esr at any point in time?
