Whenever I open my browser, it immediately sends me to “Urgent Firefox Update” page where I’m asked to accept an installation file. I cannot surf the Internet while this page is on. Only rebooting the browser helps me get rid of this annoying notification. Sadly, it soon gets back to the browser and this “Urgent Firefox Update” virus starts bothering me all over again. How do I remove “Urgent Firefox Update” and start browsing normally again?
