HI, I am surprised you can open anything. Please use one or the other as they both do the same thing : Adblock Plus 3.1 or uBlock Origin if want more than 2 use Ghostery or something that does not work in the same way and use the same lists. So the above is your issue why you can not click on that I would think. As to being PCH advertisement page I have no idea but would think the above 2 would take exception to that. As well Firefox's Tracking Protection feature may be a factor : When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: *https://support.mozilla.org/en-US/kb/tracking-protection Please let us know if this solved your issue or if need further assistance.
