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

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?

Recently, in last two months, when using the Firefox website browser, I cannot print some, but not all, website articles on my Brother Laser Printer. Articles from Website www.zerohedge.com will not print. Articles from other websites print fine. My Firefox version is: Firefox Version 156.0.1, Build ID 20260921121718. other troubleshooting information: User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:156.0) Gecko/20100101 Firefox/156.0 OS Windows_NT 10.0 26200.

I am running Windows 11 home, Version 25H2, installed 7/9/2026.,

I have cleared the "saved print settings" button with no solution. Still won't print.

Your thoughts please. Kind regards, John T.

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 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

Hello, After Firefox removed about:config option from Beta and Nightly, can you tell me how to remove Header and Footer when I print documents? I don't want to include URL, dates, times etc. but a clean document or file?

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 few updates ago, headers and footers started appearing on anything I print from Firefox. No other printing from any other source does this. All the settings (advanced settings) show header/footer as off, and 'none' in all the header footer options. I have attempted every combination available and can't get rid of the headers and footers. I Don't Want Them!

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.

When I in Firefox try to print a page from Google Kalender (Swedish), it just turns out blank. All other kinds of printouts , e.g. Word, web pages, etc., works fine. This problem started some weeks ago. Please help! Thank you!

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.

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.
