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?

After I print a page, Firefox seems to remember most of the options I chose for next time.

For example, if I print using some custom margins, Firefox will default to those same custom margins the next time I print a page. The same for duplex options - Firefox remembers that I want to print double-sided and with "Flip on short edge".

However, it doesn't remember my "pages per sheet" settings. It's annoying because I always print 2 pages per sheet, but Firefox defaults to 1. So I need to change that setting to 2 every time I print. If I forget, I wastefully use twice as much paper.

I've checked in about:config and `print.save_print_settings` is set to `true`. Like I say, most of my settings do get saved, but not "pages per sheet".

Is there anything I can do to set a persistent preference for this?

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

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?

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.

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?

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!

I'm not sure if this is a FireFox issue or a google glitch, but here goes. Please give me direction on how to correct the above mentioned problems.

Thanks in advance for your time.

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.

We print a report from an application, and the application allows the user the option to print the "title" of the report. Once the option to print the title is selected and print report is executed, the report displays in the browser, which can then be printed to a printer. On one machine using Mozilla, everything works as it should, but on a second machine that we are starting to use, even though "print the title" is selected, the title does not appear on the final print output.

In other browsers I see a "page setup" option and that is where I can select "Title" and position where I want it to appear on printed output, and I suspect Firefox must have the same settings, but for the life of me, I can't seem to find it.

I've included the images of the various stages that we are trying to achieve with Firefox on the new machine.

Any assistance would be greatly appreciated.

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 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.

We recently had an update on our printer drivers and somehow this has swapped settings from the previous system print dialogue to "Firefox - Print". The Firefox print dialogue does not have print preview and I need to be able to see a print preview. I've noticed that this was an issue in the past and people have solved it by going into about:config and setting print.tab_modal.enabled to false, but this hasn't worked for me. I am asking this question because if I can't find a solution I will have to switch to Chrome so I can see a print preview and I would rather not. If there is another way to force the system print dialogue instead of Firefox, please let me know.

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.

Hi everyone,

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).

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?
