If you already got Quantum (and why wouldn’t you, its awesome!) I’d recommend getting previous version of Firefox, such as this Sep 2017 release and install to different folder than your Quantum. Make sure to disable Firefox updates.
Get Opera portable browser, and install to folder on the desktop, you can delete it when finished or keep till next time. Video below page break will tell you how to add VPN. You’ll need to enable Chrome extensions with this addon.
Install Chrome if you do not have it, if you do, go ahead and install Windscribe extension. Video below has process outlined for major browsers.
Windscribe is a Canadian VPN provider with ad blocking and privacy features that are not always available with different providers. Interestingly it comes with both Windows application and browser extention, depending if you need all or only World Wide Web traffic routed through their service.
Windscribe is currently offering 40GB signing up bonus (no purchase nor credit card information is necessary) for new VPN users. Including monthly allowance of 10GB, you will get 50GB of free VPN bandwidth for the first month.
