I would like to download all the files of a given type (such as pdf) linked from a web page.
I used to use DownThemAll in Firefox, but the addon is "Not compatible with Firefox Quantum".
I have tried https://addons.mozilla.org/en-US/firefox/addon/download-star/, but I don't find out how I can use the addon to specify to download all pdf files linked in the webpage. Do I miss something?
What addons or other tools can do the task?
