I've tried this more than once. I allow or temporarily allow all with No Script. I white-listed the forum in Adblock Plus. Still nothing. The search function doesn't work.
Now using Firefox 39. It's been the exact same way through several versions of Firefox. And please don't say to try IE or Chrome. I don't like Chrome and absolutely despise IE. Since version 8, I still have phalanges left over when I count the number of times I've used that nightmare of a browser. LOL!
