Install from Firefox Browser Add-ons
The current Firefox Browser Add-ons version is 4.1.0. The extension connects with ProxTek, TekLan’s encrypted browser connection: everything between Firefox and TekLan’s server is encrypted, and the extension uses its own login for this browser rather than your VPN password.
Before you begin
- Update Firefox to a current version.
- Have your TekLan VPN email address and password ready.
- Turn off any other VPN or proxy extension.
Steps
-
Open the TekLan VPN listing on Firefox Browser Add-ons and select Add to Firefox.
-
Review the permissions and confirm. TekLan needs access to all websites so that every site you visit goes through ProxTek.
-
Open the extensions menu (the puzzle-piece icon in the toolbar), select TekLan VPN and pin it to the toolbar.
-
Select the TekLan VPN icon and sign in with your TekLan VPN email address and password. Your password is used once to sign in and is never stored.

Sign in with your TekLan VPN account. -
Open Locations and choose where you want to appear to be. Select the star beside a location to save it in Favourites.

Pick a location from the list. -
Go back to Connect and select the round button. It turns green and shows Connected.

Green means this browser is protected.
Check the connection
- The extension shows Connected with a green dot.
- Select Leak test on the Connect page. It should say No leaks found and show the location you chose.
- To keep a site off the VPN (or always on it), use Website rules.
If it does not connect
- If the extension shows Allow TekLan VPN, select Allow access: Firefox has not given it access to websites.
- If it shows Sign in again, sign in again: TekLan stopped accepting this browser’s login (for example after you signed this device out).
- Turn off other VPN, proxy or privacy extensions; Firefox lets only one extension control the proxy.
- Open Settings, Diagnostics to see the last error, or Contact support to send us a ticket with it.
- Confirm your email address and password work by signing in to the client area.
