I've been using Icefilms for a couple of years now and I am having a problem with trying to download, or at least get off the source page. I'm running FF 43 with the Ice Quick Stream script. I do not have any script blockers installed.
I click on a source link and a new tab quickly opens and closes. I've disabled all of my ad blockers and such and it is still happening. I don't have the problem with Chrome. Can't say about Opera because all of the ridiculous malware ads crashed it.
I had to create a new profile in Firefox and everything worked like a charm. I don't know what's up with the last three builds, but I've had to create new profiles with each of them because some sites got screwed up.
