Hi,
I tried to use Mozilla addon „Onion VPN with speed control“ by using these instructions:
Download the installer script
Extract it in a local directory
Double-click the install.bat file to install the component
Press the “Reload Extension” button to recheck integration
It seems TOR browser will be opened with „Reload Extension“. Is it OK?
Please beware of any extensions or add-ons masquerading as “Tor” or “Onion” software.
They will not do what they advertise and alter your browser fingerprint at best, and install privacy invasive software and break the various privacy-enhancing and anti-browser fingerprinting patches in the Tor Browser at worst.
