issue with Firefox mobile (android) and pdf files

I have recently encountered an issue with Firefox mobile. Some of the pdf files from Google search doesn't display at all after I click on the link. This only limited to some if the link, on the other hand they work perfectly fine on chrome mobile. An example: https://www.google.com/url?q=https://www.nice.org.uk/guidance/cg125/documents/peritoneal-dialysis-guideline-for-consultation-appendix-b2&sa=U&ved=2ahUKEwiFzs3l6MTgAhWltXEKHdHqALkQFjADegQICBAB&usg=AOvVaw0KrFE6OBrjbRCj4XuIMzgd I initially thought it's an issue with pdf files or the links. The same link worked perfectly fine with chrome. Also, this only limited to a selected number of pdf links and not all of them, others open really fine. Kindly advice on the matter as it really annoys me, because a big part of my work depends on files like this. Thanks
