Alan, I am also in Oz, (somewhat obviously). I have never had any trouble downloading from CB+ but I have this kind of trouble downloading things from other sites. This will be a specific problem with your own PC. Advertising bots seem to latch onto downloading sites at times so they can latch up their hits to justify revenue. So you find you need to click something before you can complete the download.If you download a lot, this is becoming a worse and worse problem. I use Firefox as my default browser with CB+. A few years back a lot of people left Firefox and went over to Chrome. I strongly suggest that those people switch back, Firefox Quantum is the latest download and it is at least as fast as Chrome and is stable and secure. And does not track you! I use the browser add-ons Add-blocker ultimate, Privacy Badger and Ghostery (Which list and block trackers. (They tell me that as I write this there are 9 trackers attached and one is blocked. Where ever you go on the net you are always tracked by Google ( minimum of 3 trackers every time.) One thing you need to do is Always delete cookies every time you close a session) That's one of the sources of trackers. You can set up most browsers to do that. I also use more than one browser and have found that if I'm having trouble with trackers or slow downloads in one, I don't have the same trouble in another browser. My main second Browser is YANDEX, which I also recommend, you also have AdBlocker in Yandex and a range of other security add-ons. YANDEX is based on the OPERA engine. YANDEX is Russian but has the best built-in translation of any browser I have come across.
Interested to know how you get on.
Cheers!
