Hi,
I was facing a similar issue so what I did was remove all the cache&cookies, Uninstalled the browser, Norton, removed all the unnecessary folders/footprints. Then disabled the background processes, startup tasks, etc. Restarted the system. Finally reinstalled the browser and Norton and then restarted the system again. Now the features are working better. If anything I will add to this or similar threads. I will always suggest you to contact support to check if they have a quick or a better fix.
Best,
