I tried to search but seems no1 reported this in the forums before. Been playing viking clan for 2 weeks and 90% of the time, pop up dont come to ask for help, publish an elite chieftain needed, etc. I do see all the achievement pop ups though and all other apps works with firefox and pop ups work with all other browsers, Google chrome, Safari, etc. Could it be a setting I have in Firefox?? Help me please, I soooooo prefer FF over chrome or safari...
Internet Explorer? No, I'm being facetious; IE's a piece of crap. You said the pop-ups ALWAYS work in the other browsers? I've noticed something like that occasionally (I play VC and PC and use Firefox through Facebook if that makes a difference). Could it simply be lag (slow loading time)? That's often my problem. When the pop-up fails to appear, is there a message that shows at the top of your screen (under the address bar)? Or at the bottom of the screen?
Actually, I just tried changing my theme/skin and it seems to work perfectly now. I had walnut 2, switched to noia extreme 2.0 and all seems fine, first 5 attemps at a pop up worked!! Lucky guess, I could have tried a gazillion other things before that...
The Facebook popup is 100% reliant on Facebook functioning properly, if it hangs the issue is on their end and there is little that we can do. Glad to hear that it is working better for you.
