## 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`

![Windows Example](/files/-LeA-Tza8o9M78UDQndi)

![Mac Example](/files/-LeIkivGPZoWzOdp9GAD)

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.

## Test it Out

Navigate to the Library Databases page a <https://sites.google.com/view/tjlibraryresources/ejournals-databases>.  Under the Science Databases, select `Access Science`.

If the link provided showed up a s a 404, you are probably logged into your fcpsschools account.  Try <https://sites.google.com/fcpsschools.net/tjlibraryresources/databases-ejournals> instead.
