Q1. What is a Java plugin (also known as Java applet)? 

Java is a programming language used for the web. An applet is a small, internet-based program written in this Java language. A plug-in is a part within the Java programming language that allows for specific actions to be carried out within your web browser. 

Q2. Why does CareLink® Personal need to use Java?

CareLink Personal uses Java to upload or collect data from your Medtronic supported medical device (e.g., insulin pump) to your computer. Java is used to communicate with your device and transfer data to a secure Medtronic datacenter where it is processed and made available to be viewed in your CareLink Personal reports.

Q3. How do I disable automatic updates for Mozilla® FireFox® internet browser? 

Follow these steps to disable automatic updates for your FireFox browser. 

1. Select the “Menu” button in the upper-right corner of your browser

2. Select “Options” 

3. Select “Advanced” on the left panel 


4. Select the “Update” tab 

5. Select the second option under “FireFox updates” Check for updates, but let me choose whether to install them 

Q4. What do I do if my FireFox browser has already been updated to the latest release that does not support Java?

In order to continue using CareLink Personal for uploading Medtronic device data (e.g., insulin pumps), it is advised that you use Internet Explorer® (Windows) or Safari® (Mac OS) browsers. We will continue to work on solutions within CareLink and notify you when it becomes fully compatible with the latest FireFox version.

Q5. How do I check to see which version of FireFox I am currently using? 

Follow the simple steps below to check the current version of FireFox on your system.

1. Select the “Menu” button in the upper-right corner

2. Select the “?” help icon in the lower-right corner 

3. Select “About FireFox”; the current version number will appear in the pop-up window below the FireFox name 

Q6. If my browser already updated automatically, can I downgrade to an earlier version? 

Downgrading to a previous version is not recommended. Instead, we suggest using Internet Explorer as an alternative browser when you desire to interact with CareLink Personal. If you do wish to downgrade to a previous version of FireFox, you will need to follow steps above explaining how to disable automatic updates to prevent the system from automatically updating your browser soon after the downgrade.

Q7. When will CareLink Personal be updated to be compatible with the latest version of FireFox? 

We can assure you that our teams are actively working on solutions for browser compatibility issues such as this one. We do not have an exact timetable as to when it will be corrected but we will certainly notify you once we have further information.
