Hi gregr, I can help you, I need some information: which version of firefox are you using and from which device.

Also, could you clarify whether you mean:

• Save a PDF using the Download dialog that pops up when you click a link or button
• Save a PDF using the download button from the little toolbar in Firefox's built-in PDF viewer
• Using Print and selecting Save to PDF as the destination

Using Print and selecting Save to PDF as the destination

Cureent version 93.0 updated 10/9/21. Windows 10 pc.

Using Print and selecting Save to PDF as the destination

Hi, does the content appear on the preview, or is it missing there, too?

Does this happen everywhere or on specific pages?

If there is a bug with specific pages, you could share URLs to see whether support volunteers encounter the same issue. It's a good idea to insert a space to "break" the URL (for example, microsoft .com) to avoid having your post delayed in the spam moderation queue.

If you get this problem everywhere, could you test in Firefox's Safe/Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is running:

You can restart Firefox in Safe/Troubleshoot Mode using either:

• "3-bar" menu button > Help > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)
• (menu bar) Help menu > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)

and OK the restart. A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).

If Firefox is not running:

Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).

Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.

Any improvement?

It appears to be website specific.

which website are you talking about, could you send the link?
