This is a very solid vpn. Good price, lots of servers and easy to use settings.
However I have to bump this review down quite a bit because of the state the firefox extension is in. I found loads of dnsleaks between this extension and the chrome version which seems completely solid. I tried using the firefox browser extension for a while to see how stable and fast it was compared to the desktop application or chrome, and less than 24 hours later I noticed my ip was getting picked up by trackers and my isp was easily logging my activity.
So again tunnelbear itself is really great, but the firefox extension is borderline broken atm.
