I'm having a strange issue; I was able to download a few script mods last night, but today nothing seems to be working at all. The download counter on every page progresses through all six seconds from 5 to 0 as usual, then I receive a quick unreadable pulse of ad-related URLs being loaded (as visible as standard tooltips in the bottom left corner), followed by... nothing happening. The download page remains static as it was when it first loaded the page, with the "0" seconds displaying forever. Clicking the manual download link does the same thing: the page briefly loads a URL, but nothing changes.
This is with Adblock Plus enabled or disabled (I've disabled it entirely and still no luck), with Firefox 55 or Chrome 61.
My IP address is , if it helps track it down in your logs. (I'm firewalled, of course. ;-))
