Hi everyone,

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, generating PDFs via the print menu has worked flawlessly with FF—now I’m forced to take a detour via Safari, for example—which works correctly in the long run—but isn’t my preferred solution. I don’t think you need different browsers just to use “normal” functions. 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?

Best regards, HS

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 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.

Why when I try to print a web page does it show all values of drop down boxes since my latest update? This does not occur when using chrome. I will be switching to chrome if this is not resolved!

After last auto upgrade of firefox browser, my print function is dysfunctional. When I try to print a broker data page, 2 "boxes" of options on the page I'm trying to print, become open, with long lists of all possible options, when they only show the one option I am using on the real web page I'm using. This takes up 1/2 of the printed page, and moves the data I'm trying to print down so far that I have to print 2 pages to include it all. This is a change which did not occur when printing before the upgrade. If I switch to a safari browser, this does not happen (but I prefer the firefox browser). Help please.

After today's update, March 25, 2026. I cannot print correctly. When printing from a page with drop down menu's, Firefox is printing every option on the menu. I have tried Refreshing Firefox, Clearing Saved Print Settings and rebooting. Anyone know how to fix this?

In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.

I like Firefox with one exception. The right-click print feature is missing in the drop-down menu. I can print from the Application Menu but the 'print' feature is missing using the mouse right-click menu. The right-click feature does work using other browsers. A picture of my right-click menu using Firefox is attached. THANKS

A month ago I downloaded Linux Ubuntu 24.04.3 onto my Microsoft Surface Pro. Was never able to get the touch screen to work, but, the printer worked fine. After the recent Firefox update, however, I am unable to print. The preview page does not load. Not tech savvy, here, definitely not an administrator. How do I fix this? Thanks for any help.

I am unable to print after upgrade to ver 144.0 The print preview just spins. I can print these web pages using Edge. This same thing happens with new version of Thunderbird. Can't print email either. John Stark

I've seen the other support requests on this from the past. Setting " print.tab_modal.enabled = false " doesn't seem to work now (Firefox for Mac 141.0.3).

Is there any (2025) way to default to "print with system dialog" rather than having to choose the link off of FF's dialog every time? It makes printing to PDF (which is 95% of my "printing" from FF) needlessly tedious.

I have these printers.

"HP LaserJet M109-M112" (the Windows default) "HP LaserJet 1020"

Regardless of the value of print.sav_print_settings, the first print dialog after starting Firefox shows "HP LaserJet 1020".

If I manually put "HP LaserJet M109-M112" (no quotes) in print_printer, it reverts to "HP LaserJet 1020" the next time Firefox starts.

How do I make "HP LaserJet M109-M112" Firefox's default? Thanks.
