Running 42.2 with KDE desktop and using Thunderbird as browser.
Recently I have had to look at a pdf document available on a website. I have Okular set up as the application to use within Thunderbird so the pdf opens in Okular.
Within the pdf document are various further url links. These are shown in blue and underlined as though they were active but they are not.
How may I view a pdf document so that links within it work as active links and if I click on them I am taken to the site?
