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.

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?

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?

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.

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew

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.
