I sell on vinted, which generates a PDF label to print. Some of the courier sites add a lot of nonsense text to their labels, which I cover up with a white box to save ink. These edited PDFs used to then print just the label without the nonsense text, but since a recent Firefox update they have started printing an empty page instead. Saving the edited PDF and then opening it again in Firefox does not work. The edited labels still print okay in Microsoft Edge.

I use Firefox with online shipping and sales using a laptop. So far I've printed shipping labels through my computer to my printer but plan on purchasing a thermal shipping label printer. I can't find one that says it supports Firefox only Windows, Chrome, & Linux. I'm looking for suggestions. 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?

When I click on option/link for "Print using the system dialog box", the print preview no longer works. Instead I see message "This app doesn't support print preview" in preview pane.

About a week ago I had printed 2 copies from my Firefox browser. Next time I only needed 1 and changed it. Since then it stays at 2 and no matter what I do it won't go back to one.

How do I fix this?

Hello, I hope somebody can give me some guidance about two issues that are driving me crazy. To provide some context, I use Firefox to work from home and my primary interest is accessing government and bank sites from my country to fill out tax forms and pay said taxes, therefore the browser built in provisions that deal with web page development, shortcuts, Artificial Intelligence, Social Media are utterly useless to me. The issues are as follow: 1. I regularly access the website of the federal tax authority of my country and local state hundreds of times each day. After a while, normally two months, Firefox starts to behave like a drug addict: It develops a resistance to the security cookies from these sites that worsens over time, until eventually the websites plain out kick me as soon as I log in. The only workaround is to use Privacy Mode or another browser until Firefox starts to behave again. In 2026 this started to happen with the bank website too. 2. After a fit of rage after a failed task I was in the process of attemping to destroy the mouse when reason finally prevailed but not before I got another issue with Firefox: The browser now prints (To PDF and paper) every single item from dropdown menues in webpages that cointan these elements. I already tried re-installing the browser, doing a clear install, erasing cache and cookies, deleting profiles. Thank you for any guidance.

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.

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 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 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?

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
