At least on Linux Firefox 91, Always Preview still serves a purpose! links with the "download" parameter will open a pop-up menu no matter what, *unless* you use this phenomenal extension.

Edit: not anymore, thank you for your service o7

How can I use the last version of the plug-in？I need 1.8.5

Works as expected

J'utilisais "Inline-Disposition" jusqu'à maintenant mais elle n'est plus maintenue. Celle-ic est très légère et compatible multi-process, c'est donc parfait. Merci au développeur !

Useful Addon to preview PDFs in browser, even if the webmaster tries to force the PDF to be downloaded.

PS: Thanks for the fast update with the checkbox to disable notifications!

Perfect
