I have had a problem with printing of an app's full page. It will print all the pages but will not print some of the content. This has happened with a printer command and print screen. I've researched the problem through the online app's help page but was told I should switch to another browser. I didn't have this problem a couple of months back but suddenly have the problem with two different company app's. Any help would be appreciated.

I use Lightspeed Retail at work and it worked fine until recently. I can print labels, but if I need to print anything else, both tabs (print tab and main Lightspeed tab) stop responding. The print tab brings up the print preview popup, but gets stuck and I can't actually print. Both tabs essentially freeze and I have to close both and reopen Lightspeed in a new tab to do anything again. This has been going on for weeks, I'm not sure exactly when it started.

Since Version 145.0.2, November 26, 2025, 1. firefox won't print anything anymore. No matter the way that I select something to print (print to PDF, print to printer), firefox won't print anything anymore. The print options screen does pop-up when "print" is selected , but when "print" is selected on the print screen pop-up nothing happens. This includes the "print to PDF" function as no "save to" file folder pop-up opens to select where you want to save the pdf file to. After an update prior to the "Version 145.0.2, November 26, 2025" firefox no longer allows you to move your tabs from their original positions to the left or right along the tab bar in the browser. I use to be able to click on & select one or more tabs and move those tabs anywhere to the left or right of their original position to anyplace along the tabs bar. NOW at present, the only way to move any tab's position is by "right clicking" on the tab, select from the drop down "move tab" and selecting 1 of the 3 options ("Move to start", "move to end", & "move to new window"). You can also add tabs to groups through the "right clicking" process. Unfortunately you can't simply move tabs in any other ways without using those "right click menu options. This is VERY frustrating because I constantly move tabs (or strings of tabs) to better group them without having to add them to specific "groups". And speaking of groups, you can no longer rearrange the tabs in "groups" either.

These are both some of the most basic and general functions for firefox that no longer work in firefox 64 bit on windows 10 OS (my primary PC, but the same holds true on Windows 11). You should also note that recent updates also occured on both Windows 10 & Windows 11. I am still currently able to print from and move tabs in the Edge browser which I have had to start using more & more since these functions stopped working in the firefox browser. I've always preferred using firefox even though it is a huge resource hog, but if firefox doesn't fix these problems soon. I will have to resort to using the Edge browser over using the firefox browser. That reminds me of a 3rd problem with your "unload tab" function, 3. The "unload tab" function ONLY works if you click on and open the single tab first. The "unload tab" function ONLY WORKS for a SINGLE TAB at a time. When/if you select multiple tabs and select the "unload tab" function in the "right click" drop-down, ONLY the first tab selected and that you are currently on, using, and viewing will "unload" while NONE OF the remaining selected tabs will "unload". You need to make a way to "unload" ALL TABS that you are NOT currently viewing/using as "unloading" tabs one at a time is painfully tedious. The "unload tab" function would be a great idea to reduce firefox from being the huge memory hogger that it is, but only if you make using the "unload tab" function's use less tedious. Perhaps Mozilla should consider making the "unload tab" function less necessary, by either making the "unload tab" function automatic and not NEED to run every opened tab until said tabs are actually in use & actively being used OR BY making firefox less of the enormous resource hog that it has become.

I recently installed v. 146 for both FireFox and Thunderbird on my laptop which is running Windows 11 Pro (Version 25H2 / Build 26200.7462). Since the upgrade to v. 146 I have been unable to use my older HP printer (Laserjet 2300d) on both products. When I try to print a browser page or e-mail using either the printer icon or the "File/Print" menu selection, the print dialog comes up like normal. However, when I click on the "Print" button, my screen flashes, the dialog box disappears, there is no indication from the printer that a file has been sent and no document is found in the print queue.

My newer HP printer/scanner (Officejet Pro 8130)works fine, as does printing to my older printer from MS Edge. So, the issue is with the Mozilla products. Using "Troubleshooting Information" and clearing the Printer cache has not resolved the issue for either FireFox or Thunderbird. Nothing else like this shows up in the knowledge base.

Do I have to retire my older, but dependable and inexpensive to use, laser printer in order to continue using FireFox/Thunderbird or is there a software solution?

Bonjour, A chaque fois que j'essaie d'imprimer un PDF sur Firefox, il me sort des pages complètement noires sur une brother DCP. J'ouvre les mêmes PDF sur Edge et pas de problème pour les imprimer. Le problème vient bien de Firefox qui envoie n'importe quoi via pourtant le même driver qu'Edge. J'ai vidé mon toner de noir avec votre bug.

Printing will not show up when I select print, only save shows. What can I do? When I use a different browser it works fine. Only when I use Mozilla, I can't print.

Hello. I can't print pdf files from Firefox but I can print them from Safari on my Mac. Using Firefox, I keep getting "The operation couldn't be completed. Permission denied." I have looked through Firefox settings and can't find anything about pdf file printing options.

when printing a PDF in two side mode, the text is moved to one side, I assume to allow for binding the pages. However this function does not work correctly as some pages have the text moved to the incorrect side. I had to use MS Edge to do the job which is something I do not like to do.

One annoying feature of Firefox is that during a print process, if the web page contains an iframe and that iframe utilizes a different domain name than the original page, Firefox will not print the data contained in the iframe. As a long time Firefox user, I would suggest that if I can see the data, then Firefox should print that data. Perhaps there might be some sort of security concerns involved, however at least give me an option to override it for certain domains. I do note that MS Edge does support the printing of iframes. The issue can be easily recreated on most eBay pages that list an item for sale. The 'Item description from the seller' data is contained in an iframe and does not print in Firefox.

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.

Long-standing problem with Firefox: when printing some webpages with text on letter-size paper, the last sentence on a page is sliced off, with the remaining slice printing on the next page.

I put the same URL in the Opera browser, and across several scale factors, it breaks the page cleanly without slicing through thelast sentence.

A fix is long overdue.

I am trying to print this PDF file. When I print through Firefox, the "R" characters are replaced with "T"s Printing with any other application such as preview on my mac does not result in this issue.
