If you see a message about Intel-based apps or Rosetta when opening Mozilla VPN on your Mac, it usually means your app needs to be updated. You might see a message like:
“Support Ending for Intel-based Apps. This version of Mozilla VPN will not open in a future release of macOS.”
Mozilla VPN should still open and work normally for now, but this warning means that your current version may not be supported in future versions of macOS.

Why this happens
Apple is removing support for Rosetta, which allowed older apps built for Intel-based Macs to run on Apple silicon devices (such as M1, M2, and newer).
Very old versions of Mozilla VPN (from 2023 and earlier) rely on Rosetta. On newer versions of macOS, these very old Mozilla VPN versions may no longer open.
To learn more, see this Apple support article.
Update Mozilla VPN to fix the issue
The most reliable fix is to install the latest version of Mozilla VPN.
- Go to the Mozilla VPN download page.
- Download the latest version.
- Open the downloaded file.
- Drag Mozilla VPN into the folder.
- Replace the existing version if prompted.
- Open Mozilla VPN.
All recent versions run natively on Apple silicon and do not require Rosetta.
If Mozilla VPN still doesn’t open
- Restart your Mac after installing the update
- Make sure your macOS version is up to date
- Try reinstalling Mozilla VPN
If the issue continues, contact Mozilla Support.
