When I installed Kaspersky Total Security 2016 on my windows 10 laptop, Firefox became extremely slow. It does not have acceptable performance at all! Without AV it works fine. Additionally, Chrome and the other browsers are all working properly. Of course, Kaspersky affects the overall performance of the machine, but it's acceptable. Except for Firefox... Which is unfortunate, because I'm a fan of it!

Contact Kaspersky support. There have been some issues of late.
