Downloading Cores from the Buildbot

In the past, when I manually downloaded cores from the buildbot I used to be able to check the box in front of the cores I wanted and there was an option to batch download where all the cores I selected would be packaged into a single zip file.

The check boxes are still there, but there is no option to click to start the download. I have to click and download each core separately. Was the batch download option removed or is there a problem with my browser? I am using Firefox.

How can the cores folder be downloaded now? I relied on this for updating my cores manually on an offline pc. It takes way too much time to download all cores manually. When only people downloading the whole folder tree are a problem, could you maybe enable downloading single folders without subfolders again? That way downloading just the folder with the latest cores would work again.
