Since the Firefox Developer Edition update 152.0beta, saving as a PDF via the print menu no longer works. Although the “Save as PDF” option is available and selected by me, the job is always sent to the laser printer (which is not supposed to print it, of course). This happens on every conceivable website, so the website itself is not the cause. (Platform: macOS Tahoe 26.5.1)

For years, I’ve been able to generate PDFs via the print menu in FF without any issues—now I’m forced to take a detour via Safari, for example (which works correctly every time). So who has recently tinkered with this FF feature?

Since I can’t find the relevant setting in the FF preferences—and a “search” on this topic has been unsuccessful—I’d like to know if there’s a solution?

I can't find any way to make the settings so that the label prints correctly across the entire sheet. I tried all the settings, nothing helped. Everything prints fine in Google Chrome.

I'm using a Mac Mini M2 Pro with Tahoe 26.5. I have two printers, the Samsung laser printer is listed twice but only the fax printer of my Epson ET4850 is listed. I can't find a way either to adda missing printer, or to edit the list. I've reset the printer settings using about:support to no avail.

Can't "Save as PDF" on Mac with Firefox Developer since upgrading to OS 26.5 on 5/22/26. It has worked perfectly until yesterday. Previously, just saving to pdf didn't download backgrounds. But clicking on "Print using the system dialog" and then "Save as PDF" would download backgrounds. I have restarted my computer, removed and reinstalled my printer, but "Save as PDF" still isn't saving, only sending to printer. I was just able to "Save as PDF" on another browser. I am hoping I don't have to switch default browsers from Firefox Developer. Others I know are having the same issue using Nightly, but I was not able to find anyone having this issue on the internet.

I use Firefox with online shipping and sales using a laptop. So far I've printed shipping labels through my computer to my printer but plan on purchasing a thermal shipping label printer. I can't find one that says it supports Firefox only Windows, Chrome, & Linux. I'm looking for suggestions. Thanks

When using other browsers I can highlight an article or portion of an article and then right click and have access to the "Print" function or "Copy" function. I've tried that several times with Mozilla but don't get that option upon right clicking my mouse. How do I print or copy an article?

I use Firefox as my Browser. I have read about and activated, I think, VPN. When I receive emails with Adobe Acrobat documents attached, I cannot print the documents! Guide me to how to print Adobe Acrobat documents received by email, please.

When I click on option/link for "Print using the system dialog box", the print preview no longer works. Instead I see message "This app doesn't support print preview" in preview pane.

About a week ago I had printed 2 copies from my Firefox browser. Next time I only needed 1 and changed it. Since then it stays at 2 and no matter what I do it won't go back to one.

How do I fix this?

Hello, I hope somebody can give me some guidance about two issues that are driving me crazy. To provide some context, I use Firefox to work from home and my primary interest is accessing government and bank sites from my country to fill out tax forms and pay said taxes, therefore the browser built in provisions that deal with web page development, shortcuts, Artificial Intelligence, Social Media are utterly useless to me. The issues are as follow: 1. I regularly access the website of the federal tax authority of my country and local state hundreds of times each day. After a while, normally two months, Firefox starts to behave like a drug addict: It develops a resistance to the security cookies from these sites that worsens over time, until eventually the websites plain out kick me as soon as I log in. The only workaround is to use Privacy Mode or another browser until Firefox starts to behave again. In 2026 this started to happen with the bank website too. 2. After a fit of rage after a failed task I was in the process of attemping to destroy the mouse when reason finally prevailed but not before I got another issue with Firefox: The browser now prints (To PDF and paper) every single item from dropdown menues in webpages that cointan these elements. I already tried re-installing the browser, doing a clear install, erasing cache and cookies, deleting profiles. Thank you for any guidance.

I am trying to print a picture of our family dog to put into a frame. She dies the December 26, 2021 and the frame is a certain size that I cannot find or don't know how to do this size.

I have a Brother MFC-L2707DW printer. It quit scanning so I deleted the drivers and uploaded current drivers. It now scans and prints EXCEPT from the Firefox browser.
