I was having the same issues as the OP! I tried various suggestions from other campfire members! I use an Acer tablet. I finally removed all ad block, and PC anti virus type add on's! Went into settings and reset to the original settings! Since doing this I have had zero issues! What is interesting only campfire seemed to affected, no other forums acted up or gave me the messages, and pop ups! I suggest trying resetting to the basics if all else fails! My computer is not used for forum chat, only business!
