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.

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.

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.

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'm unable to print Yahoo emails via Firefox 146.0.1. I receive a 403 forbidden error. Listed below is the error:

Looks like there’s a problem with this site https://mail.yahoo.com/print/message/AAHdMRfbvQcEeFDcuycB940Whp3? appName=NOVATION_APP sent back an error. Error code: 403 Forbidden • Check to make sure you’ve typed the website address correctly.

Just FYI, I can go into the Chrome browser and print without issue.

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'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.

'Running ver 137 and now cannot print to my system default printer. Tried the Troubleshoot fix and same result - defaults to PDF. Is there any entry in about:config to ensure system printer is selected. I have checked all system settings and brother printer is the default.

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?

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?

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

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, I recently switched to Firefox and I have run into a problem. While printing a pdf on the "more setting" menu the percentage scale doesn't actually work. First of all the preview doesn't change when trying different scales, I thought that it might have been a preview problem and I've tried to print anyway finding out that also the printed result wasn't correct. I often use this feature and I will be grateful if you are able to help me. Thanks

After downloading a file which is saved to my Mac Download Folder the file is removed once I close the Firefox Web window. I checked the folder before the window was closed and the file was there. After closing the window the file is no longer in the folder. Also it is not in the trash.

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?

(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!
