If you are looking for an easy to use, easy to install -- industry leading VPN service, ExpressVPN is the best in the business. I have used 5 different paid VPN services over the last 10 years, but have refused to look any further since I discovered ExpressVPN. Their services have everything you could want -- if exploring the web anonymously -- is what you are looking to do. The ExpressVPN plug-in (or Extension in Firefox) links to your downloaded service, allowing you to conveniently engage the VPN when browsing online. Their easy to access click button, allows you to toggle the service (on/off) when ever you feel the need. This extension works on Linux (Android), Mac/Apple, and Windows with ease. If you have a VPN service and are not sure if it is sufficient -- make the change to ExpressVPN -- I know this company is the best in its class, hands down.
