Works great most of the time, however I did notice that it invalidates sessions when attempting to buy tickets on ticketmaster. I was trying to whitelist the domain and it refreshed too fast for me to be able to. The manual rule creation is VERY unintuitive so I am not really sure how to manually whitelist a domain. Also would like to see a temporary disable feature that allows you to turn it off for a few minutes for problematic websites.

I ended up having to use a different browser for my ticket purchase, but otherwise I love how well it works on most sites.
