Hi, I have long used the "browser.download.open_pdf_attachments_inline" setting to revert Firefox to the older style of PDF handling. I have recently setup Firefox on a new Windows 11 machine, and this custom preference is no longer working. If I change the somewhat-related "browser.download.start_downloads_in_tmp_dir" setting, then PDFs DO download to the temp folder, and still open in the browser, so I know that at least some custom preferences are working. I've verified that the prefs.js file for my profile is being updated with the "browser.download.open_pdf_attachments_inline" setting. I've also tried adding it to a user.js file, and that made no difference. Any thoughts on why this preference is no longer working?
