How can I customize the headers and footers of a print job? Specifically, I want to change where the header and footer info appear on the page, i.e., left corner, center, right corner. I'm using Firefox Browser version 141.03. Under Print > Options, the only option is to show or not show the headers and footers. There is no option to EDIT them. Thank you.

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?

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?

(April 2025) So suddenly, after my most recent FF update, if I have a document open in FF and hit "print" and choose "use system dialog box" (or whatever the exact wording is), Firefox Print opens up instead of my usual system dialog box. Why is this happening, and is there a setting I can change to DEFAULT to the regular SYSTEM PRINT dialog box instead.

I do not like FF Print. It prints one page at a time w/ like a minute pause between pages in a multi page document. And when I need more settings, it opens up the HP dialog box anyway, so wtf is the point? I just want my system dialog box back where all my print settings are in one place.

Thank you for any help!

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.

When trying to print something using Firefox it automatically wants to print 2 copies, despite refreshing, rebooting, reinstalling and checking browser settings. This issue does not occur with other web browsers such as Microsoft Edge.

Running Linux-Mint on my laptop. Trying to run an epson ET-2400 ink jet Printer. Need Driver for printer. I have seen some information about software that needs to be added to "talk" to the printer but I cannot find it now. Please someone help.

Not sure what topic this would be under but when I print a webpage from Firebox the info (page # - date and time info) at the bottom of the page will only print the top half, all it shows is the top half of page 1 of 6, etc on the left side and the top half of the 5/10/2025 on the right side, it prints the whole line of info at the top of page. How do I get Firefox to print the whole line of info at the bottom of the page?

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

Previously, when printing a website, you could select the text on the page and then click print and then there was an option (Print SELECTION) that would allow you to print only the highlighted text.

I cannot find that option on the modern firefox print window/dialogue?

The custom printer dialogue in FireFox is not good in handling non common printers or paper sizes, when printing with for example label printers it's annoying and adds an extra step since many option are not present or not sticking in the FireFox custom printing dialogue. I'd like to know if there is still a way in current versions of FireFox to completely remove this custom printer dialogue and go directly to the system print dialogue. This used to be available thru about:config setting, but it's no longer working in that way. Thanks in advance.

I have a Brother DCP-L2550DW printer that is connected via a network cable. Any other browser, i.e. Edge or Chrome, seem to be able to connect and print just fine. Firefox fails to print and there is no information about why. I have checked Event Viewer, turned off all the extensions, tried the about:config to reset printer options. Every single suggestion I've found so far fails to fix it. I have a great deal invested in using Firefox (bookmarks, etc.) so I'd like to keep it as my default browser, but not being able to print is SO annoying. Any suggestions?
