Troubleshooting speed issues on Mozilla VPN

Mozilla VPN Mozilla VPN Last updated: 06/14/2024

There are a number of factors that can affect connection speed while using a VPN. In this article you will find the most common and a few ways to fix them.

Distance from the server

When using a VPN, your data has to pass through a VPN server, sometimes a far distance away from your home location. As a result, it is normal to see reduced speed. The further away from your home location a server is, the greater the potential drop in speed and increase in latency.

Time of the day

The time of the day at the location of the servers may also cause speed reduction. For example, If you are connecting from Los Angeles at 8 AM local time to a server in the UK at 5 PM local time, there is a likelihood that the server may be busy due to local users connecting who are just returning from work or school.

Technical factors

Other factors such as device compatibility, operating system, local bandwidth and ISP (Internet Service Provider) all play a factor in speed reduction.

  3. If you find that none of these suggestions work, our Engineering team would benefit from logging the details of this issue. If you’d like to contribute, you can start by performing a speed test from a testing site like, while first being disconnected and then a second test while connected to the VPN. Take screenshots of your results and submit a ticket right from the app.

Here are some other things to include that would help us greatly:

  • Is the performance issue occurring on all websites or only some specifically?
  • Your Internet Service Provider (ISP).
  • The server location you were connected to.
