I would like to be able to download pdfs from the arxiv.org online preprint repository in the browser. These don't have a .pdf extensions but rather names such as "1108.4289".
When you click on a pdf link on the site the download sidebar comes up and the file appears with a pdf icon, but clicking the download button gives no result and the pdf icon against the name disappears to be replaced by a generic download one. There is no sign of the file in the downloads folder after this.
I have tried adding the Add Download Link patch to the browser, but a long press on the link to the pdf file and choosing the "download link" option has no effect either.
