How to Install TuxlerVPN on Firefox
Browser-extension note: TuxlerVPN for Firefox requires Premium, uses a datacenter connection, and routes supported Firefox traffic only.
Before installation, review how a VPN browser extension works and which traffic remains outside Firefox.
Installation
- Open the official Firefox extension download page.
- Follow the link to the current Mozilla Add-ons listing.
- Confirm the publisher and review the requested permissions.
- Select Add to Firefox and approve the installation only if you agree to those permissions.
- Sign in with an account that has an active Premium plan and follow the current on-screen setup instructions.
After installation
Open the extension and confirm its connection status. Use the VPN testing guide when checking its public-IP, DNS, and browser behavior. Keep Firefox and the extension updated, review its permissions after major updates, and remove it when it is no longer needed.
For a Standard plan or a residential connection, use the Windows application. The Windows setup guide explains installation, plan selection, and verification.
