It used to work fine and without any problems, but after the interface was changed, the filters I select from the interface close on their own when my computer restarts. It's not a huge problem, but it's very annoying. Even the most basic filters, like the ad-blocking feature, close on their own, and I have to deal with them every time I open it.
Other than that, it's a great app with a lot of features i'd even say it's the best ad-blocking extension.
