"however Wikia finally got me to get a adblocker when video ads caused it so three Wikia articles open in tabs would freeze browser."

I have this exact same problem when I allow ads on Wikia. The performance hit Wikia's ads bring cause the site to literally be unusable for me. One tab slows it down, two makes it sketchy, and three generally would crash my browser.
