Ubuntu – How to make Java works in browser on Ubuntu (64bit) in 2017


I need to run some old browser-based java applications. But when today I open my Firefox and try to open this app, I found that Java plugin not works. I searched Internet and find that new Firefox not longer supports Java plugin (Chrome and other browsers too). So how can I make this in-browser java application run?
I use Ubuntu 16.04 64-bit.

  • | Ubuntu 16.04 LTS 64-bit |

    • First, I have updated Java to have the latest version.

      sudo add-apt-repository ppa:webupd8team/java
      sudo apt-get update
      sudo apt-get install oracle-java8-installer
    • Then I download and unpack archive with 64-bit ESR Firefox (older version - v.45) from here

    • Then I close my 'standard' previously installed Firefox and run 'firefox' file from the extracted folder of the version 45 archive.

    And after that I open my site and successfully run Java application from it.
