This problem started yesterday and I'm unable to figure out what's causing it. On any page in the forums, members have noticed that their browser tab will go into a rapid refreshing loop; the page doesn't appear to be refreshing, but the cursor & browser tab will constantly flicker to their "loading" state. I've disabled the add-on I recently updated to see if that would fix the issue, but it's still happening. Edit: Nevermind, it seems to be an issue with one of the ads. I re-enabled my adblocker and the problem seems to be fixed.
