I abandoned IE back in the 90's in the early days when many sites were optimized for the old Netscape Navigator. Later IE had all sorts of security problems. They say that is fixed now? I still reflexively avoid IE. Protection software is in place, updated, and fully activated.
Chrome is Google, and I use Google sparingly or thru a proxy.
My problems seem to have gone away for now?
Time will tell me more. I still think it was something malicious that might have infiltrated the site, even if only temporarily. It just wasn't the kind of marketing tactic that SMF would allow.
It was obviously Firefox oriented, but Firefox doesn't do that chit themselves. Their logo is easy to duplicate.
Only happened on this site, so that is why I asked the members?
If I see more, I will update.
Meanwhile, thanks to all for your feedback.
Good luck and good smoking.
