Hello. I've recently come back to FF and am really pleased with it. However, I have recently hit a bit of a snag as follows - In a website that has PDF's as links that can be viewed - ie click on a link saying "View" the document - when I click on it nothing happens. I can right click and open the link in new tab, when I do this the same page opens again, with the same hyperlink - same thing happens when I click on that, ad infinitum. Other browsers (DDG) immediately save the PDF - so the links work on those browsers. Interestingly, some other links on the same website to PDF documents do work in FF. I have noticed that the "openable" links end on .pdf but the links I can't open (as docs) don't. I've tried disabling all add-ons, ensuring FF is up-to-date - version 112.0.1, changing all security settings to their lowest setting, tried changing what to do when FF opens a PDF, but nothing makes a difference. I think the issue is related to opening links and have toggled all the "links" settings but again, no difference. Can you help please? Thanks very much and kind regards, Andy.
