Then in the new tab, click the arrow at the right of the link to save the current page to the specified folder (or download PDF). The PDF will automatically open in the new tab. In the same way, opening PDFs in new tab will allow me to save and close my current page without using the save button. Thanks for posting this helpful tip; I was using the same method, and now it works! Mar 28, 2024 — In some websites, the default PDF links may open in a new Firefox tab when clicked with no option to save current page. I don't know how to use this for webpages, but for e-books or other websites with custom PDF links, it would be nice if it was possible to load the file in a new tab, so the browser could save the current page to the default PDF folder. I have already tried many other methods, but these two seem to work for me and I can even save the PDF as a .zip (or .rar, .go). I haven't noticed any performance or download related issues with this method. Thanks so much for your work!

Here is the link to Firefox's help : In Firefox, go to Options — File manager — Options… — Advanced — Security — Edit and click the permission menu Click the + button and enter “Read” for 'read other files.' Then click OK This opens up the Permissions dialog and asks you if Read and Execute permission is granted, and you answer yes by clicking OK. Firefox is now installed with this permission selected.
