Check for new versions of Firefox, Thunderbird

Created a little Bash script on Github that reads your locally installed Firefox and Thunderbird versions and compares them to the newest versions available for download.

You can use it if:

  • you manually installed Firefox and Thunderbird with root privileges
  • you are an unprivileged user who may not tamper with the installation
  • Firefox and Thunderbird can not automatically update local installation
  • you do not want to run Firefox or Thunderbird to check for updates
