In previous versions of Firefox (up to version 133), it was possible to automatically trigger printing of a PDF file by loading it into an iframe from a sandboxed iframe and call print. However, starting with version 134, this no longer works.

Is there any other way to automatically trigger the print dialog for a PDF file in Firefox, similar to how it can be done in Chrome/Edge (e.g., by opening the PDF in a new window and directly triggering the print dialog without additional button clicks)?

I'm using an out of date Windows 10 laptop. I am aware of the Windows 10/11 thing. I know. I've got my own reasons for not updating this one, it's not my only device. I get it. I understand. I know. My settings are how they are on purpose. I do not need to be nagged in this fashion.

How do I turn this off? I can't find it in settings. It's not appearing on any of my other browsers. It's just Firefox. Please help, it's driving me crazy.

Thanks in advance.

Receiving Popups in Firefox Trojan Virus found, System Warning.... every time I close or dismiss another pops up. It indicated it was from McAfee at first, now includes websites I removed from Notifications... I scanned via Webroot 4 times now No threats found, None removed.... So I shut everything down and rebooted. Came right back up.

I am afraid to log into anything including email but I need help ASAP!!

Since the new "feature" profiles came out, I now always have this "originalprofile" in the browser (in the title bar) and in the Windows taskbar... It's really annoying.... Now my question is, how do I get rid of it again... on 3 more pictures, Firefox language is German...

Hello: FF dev 150b5,w11p. With this v 150 there's a new irritant that I would like to stop, please. That's the sudden (starting w/v150 again) appearance on lower L corner, of a popup window, which may be interactive. That is, this thing is so new I can't say more about it except that I didn't change anything to make this thing appear, & this didn't happen in prev.versions.

I looked in settings & the only thing on keyword "popup" goes to, in "search results", is: "block popups & 3rd party redirects." I already had that choice checked from previous versions (that is, do block). But this new popup appeared (unasked) anyway.

Is there an extension that will stop these? If so, what keyword(s) do I put into the "search extensions" box to find the extension(s)?

Also, w/this new "wonder" of unasked-for popups -- is this another "coming w/AI" feature I will have to live with?

I did a search here on "popups" before posting,but came up w/nothing relevant.

Thank you.

/edit:fixed a formatting issue causing horizontal scrolling

I have a pop up that is coming through probably 50 times a day that I can not figure out how to get rid of, can someone help me? ITs a little notification the comes through in the top corner of my screen and its driving me nuts.

I terminated my McAfee subscription, as Windows 11 and Microsoft Office 360 have Microsoft Defender included. I keep getting Mozilla Firefox warning notices saying my McAfee licence has expired, Trojan Virus found on hard drive, multiple virus on my computer, Critical errors etc. I have had MS Defender do several scans and no problems have been detected. Can you help correct this or do I have a virus that Defender cant detect? I have tried to copy one of the notices but it comes up as a link to further notices and I am concerned it is another virus. The notices are all Mozilla badged with suggestions such as Scan and fix, Turn on protection, Update windows and more. I am able to delete them, but after a few minutes they return. Regards Robert.

I have have just come across this information and have no idea what add on it is referring to. I'm not one that uses much in the way off add ons. Here I am, 79 next month. I have only my desktop PC. I don't own/use a mobile phone, ipad or any other devices. I use my PC for emails and using the net for research, general information, buying products, ecards etc. I play a couple of games, Lovatts puzzles (3 games), jigzone, word wipe from Washington Post. If I have taken on/used an add on it was with limited knowledge and it certainly was not my intention to cause any problem. Does the block also mean that I am not protected from viruses or malware etc? Please let me know the outcome of your decision. Thanking you in advance. Kind regards, Rhonda Macrae. rhondamacrae46@gmail.com

I am getting constant pop up "alerts" on the right side of my screen that block my view. When I close one another pops up. It's very annoying. All of them have

the Firefox logo and name in the upper left corner.

Thanks.

I keep getting 'notifications' from Mozilla Firefox that McAfee has discovered a virus, Trojan, and other things. They come on the lower right corner of my screen and the address d3mj6kghubcc73dtudhg.kaironero.co.in is along the bottom of the notification. The notifications pop up every time I turn on my computer and go into Firefox and they just keep coming after I dismiss them. They are in small rectangles and have Mozilla Firefox written across the top left and say that McAfee has discovered.... Are they legit or are they spam and how do I stop them? I don't have McAfee installed on my computer which is a desktop. Please help--this is driving me crazy!!!

I just received a toast from a sidebar app. Unsolicited notifications are the fastest way to get me to dump your app. I recommend Mozilla implement user-level control to disable notifications from sidebar apps. In theory, Mozilla is already supposed to be respecting my preferences on notifications. I have authorized notifications from only one website, and it wasn't the one for which I received this notification. There's a disconnect there.

Hello I hope you can help me. I signed up for the Mozilla VPN yesterday but have decided to end it. It is within the 30 day refund window. How do I receive my refund please? I did cancel it under the cancellation button but it did not offer my refund. It said I had the service for the remainder of the year but will not renew at the next renewal date.

The reason I am cancelling is because when trying to access youtube, google says I have to sign into a google account where before I did not have to do that. I canceled my google account years ago and am a avid firefox user. thank you for your time.

I also downloaded the app to my phone and may have signed in that way as well. Thanks.

How can i download a pdf of my passwords. I think i need to set up a lock screen first. Please give precise instructions how to accomplish both these tasks. Im having great difficulty signing in and out of sites so until i figure out how and why things have changed i need a list of passwords. My device is currently unlocked. I have trouble finding my way back to my questions here. Why doesnt firefox have a history function? Sometimes it does but its not recent. I put all these questions together because its too difficult finding my way back to every individual question. I have a hundred questions about firefox so many that its daunting to consider as it would take me days to do and its time i dont have. Somehow my firefox account has gotten too confusing and complex
