Firefox Community Forum

As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

for some reason my youtube tv claims it needs to be updated so can not watch tv in settings it claims to be the latest version 115.29 but google claims it is 144.01 so have no clue how to update if that is why I can not watch tv trying to ask mozilla is pointless with there b/s excuses which is part of firefox

Hi this can anyone shed anylight on this please? I was using Facebook earlier today with no problem then now it won't run nor open yet it runs fine in Google Chrome. I've cleared out the Cookies ect and re-tried but its not pitching anything.

Many thanks Rob

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

When pasting an image from the clipboard in Outlook Web Access in Edge there's right mouse button option to "Paste as Image". This places the image inline. In Firefox there's no option like this.

Safe mode (troubleshooting mode) doesn't fix this. Ctrl + V or Shift + Ctrl + V doesn't fix it. Shift RMB to get Firefox menu does show Paste and Paste without formatting but it doesn't paste any inline image.

I've attached a screenshot of Edge and Firefox with the Outlook context menu and Firefox context menu.

Firefox version: 140.0.4 (64-bit) Edge version: 138.0.3351.83 (Official build) (64-bit)

There seems to be a glitch that I keep encountering when trying to sign in through my TV provider, particularly Verizon, to watch DisneyNOW or TCM or any other service for that matter. The website known as "ssoauth.verizon.com" seems to keep hanging on the message "Please wait - we are verifying your account," and the sign in never gets completed. I already tried clearing my cache and history but with no result.

Even trying to submit troubleshooting information is causing the form to crash here. If you would like, I can send you a text file containing the log I saved from the browser console.

Hi,

The Linked in pages are not appearing properly.

I have attached the images of the following two pages,

Please arrange to do the needful.

I noticed I cannot log on to amazon.ca or shaw.ca anymore on firefox, why?

Suddenly NY Times links think I am a bot, or there is a java problem, or I am clicking too fast (huh?), and I am being blocked. This started around the same time as the last update. Help! Thanks.....

Even i try to upload an image via classic upload-button the same problem reproduise. On other sites there is no similar problem, as well as trying to insert the same image but inside the application windows.

In attachement: yandex/google and default image i was trying to upload.

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!

Dear Helper,

since the newest Firefox update, i got today (16.09.25), the audible cloudplayer doesnt work anymore, meaning it wont load the audiobook! I emptied the cache, but nothing changed. I tried the audible cloudplayer with Windows Edge and it works fine, so it is a Firefox specific problem. I granted all websides access to audio and media automatic replay, nothing changed. The cloudplayer doesnt work! So my question is: What else is interfering in Firefox with the loading of the player? Thank you so much in advance for your help :) Yours sincerely David

Yahoo Finance stock charts are not loading. Never encountered this problem before this week. A GeekSquad tech support person was not able to fix the problem and recommended I contact Firefox. Edge and Chrome load Yahoo Finance stock quote sites just fine; I'm only having trouble with Firefox. Any ideas on how to fix? Thanks! Carol

Unable to log into SSA since the update (it seems however since you are changing this weekly or hourly it seems sometimes I do not know what the version was when I logged in last) I am at 144.0 and can log in without an issue using Chrome. How can this be fixed? From what I can tell it seems to not allow a return from server when you click on LOGIN on SSA <ssa.gov/myaccount/> I can get in with out a problem using Chrome. Please let me know what the fix is.

In Firefox, the animation exhibits performance issues like stuttering, particularly in elements that rely on animateTransform and animate for movement or opacity transitions. This issue is not present in Chrome, where the animations run smoothly without any noticeable lag.

Expected Behavior: The animation should render smoothly on both Chrome and Firefox without any stuttering or lag, providing a seamless experience for users.

Steps to Reproduce:

Open the provided SVG code in Firefox.

Observe the animation, particularly the elements with animate and animateTransform attributes.

Notice the stuttering or lag compared to the smooth rendering in Chrome.

Hello, you keep coming up with new and different ways to use Firefox, but you are not able to fix it to where Firefox can be used with too many websites. I am constantly having to use Microsoft Edge to connect to Hulu and The Hartford Ins. Co., just to name two which I use frequently. I don't like it, especially the problem with Hulu, which I use a lot, being retired. There are several other websites with which I have problems when I use Firefox, but can't think of them right now because I use them much less frequently.

I would be eternally grateful if you could get those problems fixed once and for all. Oh yeah, I do contribute do Mozilla once or twice per year.

Thank you, Gabrielle Pine [email address]
