You MUST have set your Ion/CSL password before you can set up your TJ Proxy.

Updating Firefox

This guide uses Firefox Quantum (Firefox version 57.0 and above). Menu designs changed and look very different from every version below that, so the guide will not accurately describe the steps you should take if your version is lower.

Steps to checking what version you have

For Windows

  1. Press Alt

  2. Mouse over Help

  3. Click About Firefox

For Macs

  1. Click Firefox at the top left

  2. Click About Firefox

If your About Firefox window shows Firefox Quantum, you have a late enough version. Otherwise, you will need to use this menu to restart and update Firefox until the About Firefox window shows Firefox Quantum.

Open the menu by clicking the three bars at the top-right and click on Options

  1. Change the time range to Everything.
