I posted re the same problem in the other thread here...I am presently using Apollo browser on my iPad...instead of Safari. So far there have not been any problems (knock wood), which leads me to believe the browser is the answer. Apollo is free at App Store and has built in blocker-- I've had it for long time. I also ot ice no ads between comments as with Safari. I use Firefox on my desktop and laptop...none of the afore mentioned problems to contender with as on iPad. But I use the Firefox blocker. I hate to say, I only have the iPad probs on QB...but it won't deter me from visiting!
