I have no issues with popups using a computer with Firefox and Adblock+, however trying to post with an iPad has now become difficult. I do not mind the occaisional popup but there is at least one that cannot be cleared. it requires closing the MTF window and reopening it. Not good when in the middle of adding pictures.
I keep getting one that says I have to update my flash player to get this site to work right. I didn't bite. I too had to exit a few times to get the site to come up. Also had a few that Norton blocked. Only happens here. I wonder if that is why the traffic here is way down.
I had to install an ad blocker on all my devices I use to access this forum in order to make it usable. It was unusable for me with all the crap ads, such as the bogus adobe flash update that was continually interrupting.
I had problems in the old format as well with popups making it nearly unusable some of the time. After the update I couldn't even open the page for several days because the same fake flash player update popup kept invading. I finally installed AdBlock as well and it's been fine since. If I pause the service at all, the ads take over again so it's definitely working.
