Hello Community.

I've selected an option to open PDF's in Firefox for preview. And if I wanted to download the PDF after preview, I simply clicked the downloab button from the preview app/tab. The files were downloaded with default filename and to the downloads folder without prompts. But since a while ago the dialog where the save location must be selected and filename given for the file opens up after the click of the download button.

How can I change it back to the previous behaviour without having to input filename and select the file download directory?

Help continuously mentions something about clicking a "shield" to the left of the address bar, yet my up to date Firefox shows no "shield" anywhere i can find. Has an update obviated the need for it, and if so, do we have updated help files to reflect the new control for security, vpn and cookie usage?

We got an alert when opening Firefox on our iMac yesterday suggesting we "refresh" and that bookmarks and saved passwords would not be affected. After the refresh, bookmarks were retained but all passwords wiped out. Further, as we painstakingly looked up or created new passwords on sites and entered them, the usual Firefox alert would come up asking if we wanted to save the new log-in, user name and password on each site, we'd select "yes" and then find none of them saved. Can anyone advise us? We're rebuilding our saved passwords on Chrome now but have had Firefox as out primary browser for over a decade.
