I get a "Sorry, the video player failed to load.(Error Code: 104153)" error when clicking links from a search for a video, if that video is available on YouTube it opens and plays just fine, not from other websites though - and it should. Fix?

Firefox crashes whenever it would need access to my camera or microphone. So far it has only happened whn trying to access a Roll20 game with camera and microphone connectivity, and when trying to access a video appointment for Universal Credit. It never happened on Windows 10, but since updating to Windows 11 it happens every time without fail, and the crash is immediate.

Whhhhyyyyyy am I suddenly unable to access certain parts of the Delta.com website?? I had no problem with the website re my outbound flight and now I can't access any info on my return flight on their "flight details" page. They had to send me a screenshot of what they had on their screen because I cannot get it on my own screen. I am worried as I get closer to my departure date that I still will not be able to access my flight info and will not be able to check-in! They told me to change browsers! Help! 😳

Presently 142.0.1 (64-bit) installed; previous updates/downloads had no problems.

Now, however, going to https://www.firefox.com/en-US/?utm_campaign=SET_DEFAULT_BROWSER and attempt a download results in this (image).

Any solution to this?

Thank you.

Hello,

I was customizing my background by loading a picture. It's adult in nature. It should be my computer in my in my private home. When something amazing started happening. If I load ANY image with a naked woman on it After a few minutes Fire fox auto removes it. I have done this 30 times. I use ANY fire fox picture it's fine stays there forever. Load ANY picture with a naked woman on it and poof 2 minutes later it's gone. So please can you explain to me why whats claimed to be the most private and secure browser around is censoring me in my own home about what backgrounds I can have? I find this highly disturbing. And I am quite serious I have had them removed at least 30 times. I'm 56 y/o If I want a naked woman on my background it should be my business not fire foxes. Also no chrome is not doing it. neither is windows. It's Firefox removing them. Any explanation would be nice.

Hi,

I started to notice recently that calendars in some websites I browse with Mozilla are inaccurate. The dates like months, days,... are in a mess. Then I used Google Chrome instead of Mozilla and it went right. It was accurate with Chrome browsing those sites. Did you hear of the same problems with Mozilla ? What can be wrong ?

Thanks for your insights,

All the best,

Denis

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

When I do "save as " action for an image in the browser it opens dialogue window to save selected image. Unfortunately it displays files and folders in some random order, rather than my preferred order (sorted alphabetically by name, followed by sorting by type).

I can see no rhyme or reason to the way Firefox lists files and folders in the dialogue window, so every time I am saving an image I have to sort things by name and type before I can find what I want.

This is not permanent so I have to repeat this action every time I save an image.

How do I, please set application preferences? to make this setting permanent?

For some reason all of a sudden my bookmarks don't show their identification icons that are associated with that web site. Those icons are to the immediate left of the site address. I used to use those colored icons as a quick reference to select the web site I wanted. Being I have MANY bookmarks, those icons to the left weer a GREAT help to locating a specific bookmark.

   How do I get my bookmarks to show the way they used to show before? Is there a way to show my bookmarks to a earlier date? Maybe that way my bookmarks will show the way they used to ?
   Can someone please help. This new bookmark menu listing I now see is not user friendly! Thank you.

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.
Super User
Ask Ubuntu
A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”
Reddit

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.
Reddit+1

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit

Thoughts? Solutions?

Thanks in advance.

Is there a way to completely opt out of having AI in my browser?

I find recent implementations of AI in Firefox quite frankly disgusting. I don't want to see it, I don't want to use it, I don't want it suggested to me. Not only it's unneeded, but also all your LLMs are a waste of electricity, fresh water and are a threat to my privacy, and we don't even mention all the legal trouble AI scraping creates.

I need a switch to completely remove any mention of LLMs/AIs in my Firefox browser unless I search for it on the internet (and, trust me, I wont; I'd prefer to continue thinking for myself and having real people with skills and talents do things if I can't do them myself) and have none of them touch me in any way. Kill that thing with fire.

Ideally Firefox, one that advertises itself as a secure browser with respect towards its users, shouldn't have any mention of AI in the first place, you know. But since companies are in a craze about it for some unknown reason (trust me, we don't want it; if I want to be lied to, I'd go to a paediatrician to talk about my symptoms, not a language model I can't trust with my data), at least give your users an option to get that awful thing out of their browser it they want to.

Have a nice day. <3

PROSZĘ zróbcie czułość rozwijania bocznego panelu. Nie wiem czy to tylko w ostatnim czasie ale bardzo ciężko najechać na coś kursorem blisko bocznego panelu ponieważ ten odrazu się rozwija. Jestem zadowolony z tej formy kart przeglądarek więc chciałbym przy niej pozostać, natomiast ta czułość rozwijania kiedy kursor myszki jest stosunkowo daleko jest irytująca i znacząco utrudnia korzystanie z przeglądarki.

Hi, I'm using Firefox 142 on Ubuntu 24.04. It's a fresh install. I cannot sign in icloud.com with Firefox even though it works with other browsers like Brave. I deleted all cookies and site data and disabled extensions (KeePassXC). It doesn't help. I tried in new private window. No success. I copy my password from a password manager, so, no, I haven't mistyped it.

Here's what I do:

1. Open Firefox and go to icloud.com
2. Click on the "Sign In" button
3. Enter my Apple-ID and click on the arrow on the right end of the "Email or Phone Number" field

At this point Brave behaves differently than Firefox. See below for how Brave behaves.

Firefox: -> A "Password" field appears (no buttons "Continue with Password" and "Sign in with Passkey")

1. Enter my password and click on the arrow on the right end of the "Password" field

-> Error message "Failed to verify your identity. Try again" appears. See icloud.png

Brave: -> Two buttons "Continue with Password" and "Sign in with Passkey" appear. See icloud-with-brave.png

1. Click on button "Continue with Password"

-> A "Password" field appears.

1. Enter my password and click on the arrow on the right end of the "Password" field

-> 2FA code is sent to my iPhone -> "Two-Factor Authentication" form opens... etc. complete sign in successfully

Please help!

Unfortunately I cannot attach the HAR file from the login sequence because the password is included. However, I attached some screenshots from the Web Developer Tools. It seems to me that the login flow with Firefox is broken. I can't tell who's to blame, Apple of Firefox. The error message with Firefox is always the same, no matter whether I enter the correct password or rubbish. In Brave, however, there is a more precise error message when I enter a bad password. See icloud-with-brave-wrong-password.png
