Its very odd as I have no freezing myself though my ISP only offers one DNS which is prone to failing.
You can always manually ad the DNS to your card of 18.104.22.168 which is Googles itself. It will speed things up.
That aside, when browsing RF from another box here which is a stripped down OS i see the ads and they load fine (no dns edits).
Google claims its us. I need screen caps, routing etc to even get them to care because in reality it is showing and counting on their end.
When I get the data of what has officially served it is the same with minimal variance over 1000 loads, meaning left and right have loaded almost 100% equally.
So yes, you have a few options. You can use adblock
for firefox as everyone recommends or you can support the site
. Obviously I prefer the support as it does go towards the cool stuff we develop for the site but at the same time if you cant spend it you cant spend it.
I am locking this as it has been covered more than a few times in the last few days and the solutions are the same.
TORKiT. You may consider unplugging your modem for 10 minutes and replugging it in. That may cure the issue as well.
