The *Edge Software *module provides you with all the tools needed to manage updates and upgrades of the edge devices managed by Litmus Edge Manager. You can upload the `.upd` file onto the admin console once and it can be used to upgrade edge devices using the Litmus Edge Manager Admin Console *Software update *options. All the images that you load onto the admin console are available for edge device upgrades.

You can create groups of edge devices and update them at a specific time or immediately using the upgrade options. You can ensure that edge devices are running on the latest version, manage the disk space used, and view a history of updates.

The Software Images list shows:

- **Product:** The product name
- **File Name:** The name of the `.upd` file
- **Size:** The file size for the `.upd` file

# Troubleshooting 

## Firefox Upload Error

When using the Litmus Edge Manager Admin Console with Firefox to upload a software image, an error can occur due to a problem with the way Firefox manages certificates.

::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/R_URmSBUDT7FlsajFrA0U_image.png" size="80" width="565" height="157" caption="Failed HTTP response during Firefox Upload " position="center" showCaption="true"}

Litmus Edge Manager uses a self-signed Certificate. This prompts the browser to display an error message. Follow the browser guidelines for how to bypass a self-signed security error message.

## Resolution

To resolve this issue, the certificate for the **Minio** application, which manages the uploaded images, must be accepted.

**To accept the certificate for the port 8445:**

1. From the Firefox web browser, enter the IP address and port `8445` (for example, `https://192.162.2.18:8445`) in the URL bar, and then press **ENTER**.
2. Click **Advanced**
3. Click **Accept the Risk** and **Continue**.
4. **Close **the browser tab. No login is required.
