Since the Firefox Developer Edition update 152.0beta, saving as a PDF via the print menu no longer works. Although the “Save as PDF” option is available and selected by me, the job is always sent to the laser printer (which is not supposed to print it, of course). This happens on every conceivable website, so the website itself is not the cause. (Platform: macOS Tahoe 26.5.1)

For years, I’ve been able to generate PDFs via the print menu in FF without any issues—now I’m forced to take a detour via Safari, for example (which works correctly every time). So who has recently tinkered with this FF feature?

Since I can’t find the relevant setting in the FF preferences—and a “search” on this topic has been unsuccessful—I’d like to know if there’s a solution?

I am no longer able to open in Mac Preview or save when hitting Command + P, then 'print using system dialog'. It will only print instead. For instance, I save certain web pages as PDFs using the print dialog and now it will only print when trying to use either the save or preview options. Command + P, print using system dialog, then I choose either save as PDF or open in Mac Preview, but as soon as I do one of these it will only print. I am able to use save in the drop-down list of printers, but I need to be able to open in Mac Preview.

I have always, for 15+ years, been able to use the system Print dialog box to create a PDF.

But as of updating Firefox to version 152.0 (aarch64), all buttons related to Saving a PDF, etc. send the document straight to the Printer to print a hard copy. There no longer appears to be any way to save a PDF.

Example scenario: 1.) Visit website 2.) Select Print (cmd-P, File > Print) and open the 1st print dialog box 3.) Select "Print using the system dialog..." 4.) Select PDF in the 2nd dialog box. 5.) You used to be able to save the PDF at this stage, opening Finder, naming the file, and choose the Save DIR. However, as of this latest update, even after the Finder File Name dialog box, hitting Save at that stage sends it to the printer to print a hard copy.

Pressing PDF, Save as PDF, Open in Preview, and Save as Adobe PDF all send the file directly to the Printer to save it.

I've got tons of receipts and things to save for work in PDF and FF was always great at this. What happened? Is this a feature or a bug? Any and all advice is welcomed.

Running macOS 26.5.1, M2 Pro, macbook pro.

My FF Browser introduced a vertical row of rings which I want to get rid off. Im using W10 and FF Version 151.0.4 (64-Bit). Rings are stable, updates show them again. Any Help???

Moderator note: Moved from the Firefox for Android forum to the Firefox Desktop forum.

In this version of Firefox 152 for windows I'm currently unable to remove search related to google, ebay, perplexity and bing.

Please return possibility to remove those completely!

I don't want my browser to have anything to do with those listed above. I have had it removed in previous versions. Why did you add it to browser again?! Why don't you allow to remove it anymore?!

After running an update, when launching Thunderbird it says "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?". Rebooting does nothing, I'm prompted with the same message. Tried re-installing the latest version - it gives me the same error message before re-installying, and also un-installing the version I have on my PC - it also prompts me to restart to finish the earlier upgrade.

I'm using 2019 MacBook Pro 16" with OS Tahoe 26.5.1. When I click on "Print using system dialogue box" it takes me to the Mac print dialogue box as expected. When I select the option to open the page as a PDF in the Preview app, it sends it to my default printer to print instead. Very strange behavior. It only started doing this in the past week after installing the latest Firefox update (152.0 (64-bit)). I haven't downloaded any new programs and it happened well after the last OS update. I've reset my printer settings in Firefox, I've tried repeating it in "Troubleshoot Mode." No luck. The error doesn't happen in other applications like Mail App or Safari. Thank you for any insight or fix you can think of.

Hello there, I use Firefox on Linux and on my Iphone. On the Iphone, when I type in asomething in the search bar, on the bottom of the app I can select with one click, which search engine to use. On firefox desktop, this needs more clicks and I would find it helpful, to have the engines shown next to the text and be reachable with one click. Thank you for this great browser!

Hi, I have multiple email accounts. To access the passwords there is now a prompt asking for an email and password- some 'identity'.

How do I know/guess what that might be?

v128.14

Thanks David Lawrie

In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

I've been trying to find a way of synchronising Thunderbird data, principally addressbooks, messages and calendar data, between several PCs. I've tried to do this with a file synchronisation program called Allway Sync but it's become clear it's not just a case of copying changed data between the profiles of the different systems.

It seems the only way to do it is by exporting the profile data to a zip file then importing it to the other systems. That would be a rather clunky solution but I could live with it. However the size of the profile folder on my main workstation is now around 5GB so that doesn't appear to be possible.

I should be extremely grateful for any suggestions on how to accomplish the synchronisation if it is at all possible.

My main workstation is running Windows 7 Professional SP1. The others are running Windows 10 Home and Windows 10 Professional

After reinstalling my computer system, I logged into my Firefox account again, but the data synchronization failed. All my previous data is gone, including bookmarks, passwords, and widgets. What happened? I can't find them in the mobile app either.

Everytime I open firefox, a small window opens that tells me "Update available Download the latest version of firefox, Download or Dismiss". Hitting download saves the update for ver 151.0.4 to my harddrive. I have several of these files because of all the times I've updated forgetting that its already been updated to 151.0.4!

Why do you keep asking me to upgrade when I already did?

To get here I went to "mozilla support" and I clicked the box requesting you send me an email when someone replies to this. This "someone" implies that this person is part of your "community" not a mozilla employee, which is what "mozilla support" implies. After taking my time to follow your vague directives, I dont expect to get any help from you but I am hopeful.

I tried adding images which took me away from this page and when I tried coming back to this page, everything I typed was gone so I had to start over. So I'm not going to click on "share data" for the fear the same thing will happen. Thanks for that

My machine Intel i3 6100, 16g of ddr4, windows 10. 250 gb ssd +1 tb mech hard drive

Over the last week or so, I call up Thunderbird then when I click on anything, it just comes back "Not responding" Any ideas?

Thanks in advance Tony Sneath

All of a sudden every time I open something in an email it automatically creates a new tab. When I delete what I have open it takes me out of my email account and I have to delete the tab to get back to my remaining emails. I have changed nothing so I am confused as to why it has recently changed.
