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.

Browser doesn't click elements on first google page. Neither "people ask" elements, nor "more images" and images even. But only on the first page. When I change to "images" tab, then it's ok. Plus doesn't click elements like left, right arrow on images on reddit.

Tried without extensions, new profile. All the same.

Why the hell do I have to keep signing in to show my passwords? I do not sign out but yet when I try to sign in to anything that I've used a password before the damn thing is not there. I'm getting disgusted with firefox and I've used it only for many years but you keep screwing around with something that worked fine and now it's all screwed up. I wish you would just leave things alone. I was having a problem with getting my bookmarks and favorites but it appears that has been fixed. I had to delete and re-install farefox several times to get all that back but lately it's staying there.

Need to delete a company I used to work for off Firefox, when I go on the page, your system always tries to load their page. I don't want that; I want them removed. https://cms.northstaria.com/

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

I have an account with Songsterr. It's a music tabs site.

I moved over to Firefox as my primary browser relatively recently & I've noticed that the captions in Songsterr are all messed up. I've been on to Songsterr about it & they cannot solve it but, on a whim, I checked Songsterr in Safari & everything appears normal so I'm going to assume for the moment that this is a firefox related issue.

I've added 4 screenshots. The first two are from Safari & show how the captions should appear. The second two are from Firefox & you can see that it's all messed up.

I found an article on Reddit that may be related but I wanted to check here first & see if any of you could shed any light.

I'm using

Thanks. :)

After i sign on to Amazon & some other sites it wants to send me a verification code before I can get on. It says this is Firefox that is demanding this. I am fed up with having to do this. I signed in to my account and the 2nd verification app isn't even downloaded or enabled.

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

Since updating to Firefox 141.0 (Win11), I've had issues with performance and on-screen behaviour of dynamic web pages/sites. The problems do not manifest on Chrome, or on a reinstalled version of Fx 140.0.4 on the same computer running at the same time (and with copy of original profile's data files, extensions etc.), they do manifest on a new Firefox 141.0 profile with only one tab open.

The problem happens on dynamic pages (e.g. gmail.com, boardgamearena.com/lobby) but doesn't seem to happen on static pages. Note that this doesn't depend on page elements moving around the visible window (e.g. panels opening and closing).

The manifesting problems:

• Screen pointer rapidly switching between standard arrow pointer, mouse with index finger (clickable link) and serifed-style insertion bar, even when positioned on a part of the page that is not a link or a text box. Video (MP4, <1MB) showing behaviour at https://imgur.com/a/absjTh4.
• Browser intermittently fails to respond to browser actions (mouse clicks, keyboard entry)
• Small increase in browser CPU usage

Problem is worse if general CPU usage (from other applications) is already high - low CPU usage reduces but doesn't eliminate the problem. (Established by changing my BOINC settings and/or snoozing BOINC and observing; I have a gadget that monitors CPU and other resource usage.)

The fact that I can see the problem occurring on Fx 141 but have Fx 140.0.4 working fine at the same time on the same page, suggests that this is a Fx 141 issue. Regular malware scanner and an alternate found no issues.

Happy to do more diagnostic testing if it's helpful.

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

I get asked to update Mozilla every time I get on my computer.  It asks if I want to allow it to make changes to my device.
I never had to do that before. Why is that happening now? Is this Update request legit?   how do I disable it or customize  so that Mozilla asks me for an update only when there actually has one?

I have dismissed this request for the last week or so. Today, my browser would not work till I hit the Update button. What is going on? Is this from you Mozilla or have I been hacked? (I have McAffee security) I also updated my system to Windows 11 a few months ago. bold text.

Any Ideas what is going on? About July 21st, 2025 I started noticing with a couple of browser tabs open, a new tab opens autonomously and flitters in the new tab name area, what "looks like a TagID", then closes by itself. I define "looks like a TagID" as something that looks like a tag at end of article link in popular newsletters I see, and appears in the url bar of the linked article.

The occurrence of the new tab happens when I open the browser, within 1 minute and occurs randomly during the session, perhaps every 20 minutes.

My first suspect/assumption is I am always signed into Mozilla when I open Firefox 141.0 (64 bit), processing an update now, Aug 5 2025. I have subscriptions to VPN and Monitor and I have sync (passwords and bookmarks) with my mobile instance of Android Samsung Galaxy phone.

My Desktop is set up as Windows 11 pro with one employer InTune acount for Microsoft but I limit that work to Edge browser.

Hey!

Anyone has any ideas why the extensions does not work properly anymore? Or is in similar situation?

My browser has been updated, as well mentioned extensions (its only 4 of them really). They worked fine for years and now suddenly - when I click on them - there is no response! I refreshed and re-installed the browser as well. Restarting does not help either.

No matter how many times I visit Amazon.com, it WILL NOT show up on my Home Screen as an ICON. I have tried 2 Rows and 4 Rows. I visit amazon many times in a week, sometimes many times in a day and it never shows up on the Home Screen after my last Firefox Upgrade to 142.0. Before the upgrade, it was always on my Home Screen. I have deleted many ICONS hoping it would somehow fill in as I visit Amazon - but it's not happening.

How can I fix this?

Thanks!

i have a big problem with settings of privacy and security. the problem is i cant edit this option ( Allow Firefox to automatically trust third-party root certificates you install ) and its greyed out . i made everything ( refresh - troubleshoot - uninstall ) and with the first click on singing my account on Firefox and add my restore my add-ons after setting up windows this option become unavailable (greyed out) and cant edit it. i need a solution without going to set up a new windows because its so tiring to set up a new windows to edit this option. please give me a solution its emergency. thanks a lot.
