This has worked fine in the past, and works now in Chrome, but not Firefox. URL is https://outlook.cloud.microsoft/mail/?bO=1&msalAuthRedirect=true&sessionId=20fbbbb0-2fa6-4848-8fec-c20c6d3a8be4

Here's the error message

When I search Google Images in Firefox, this pops up. I tried using an extension to hide it, but I can't see the rest of the image, which is inconvenient. Microsoft Edge and Google Chrome load it, so it's not an issue. Is this a Firefox feature? It's a hassle to disable the extension just to read the rest. Could you please give me some advice?

I am having issues using the search functions on car rental websites for National, Enterprise and Alamo car rentals. I enter in all the needed info for location and dates, but when I search, I get an error message that says try again later. See attached screenshot. I am using Firefox 150 and Windows 11. Other car rental sites work fine and I've never encountered this issue before.

when i login my google account on firefox they say this browser is not try another browser. and if you already use supportive browser then try again and if click on try again and try it they still show me same statement.

Facebook Games - I get this: "Sorry, your browser does not support this feature. Please use a different browser and try again. " What do I do? - 10/20/2025

georgiasown.org does not fully function in firefox browser. The website opens but some of the graphics are missing and when I click on Log In nothing happens. This started about two weeks ago. Have been daily going to this website for over 10 years in the Firefox browser. I do not have this issue when using Microsoft Edge browser.

Kind of a combination 'Browse/Download problem. This morning on rising, 07/11/25, Claude.ai's html artifacts quit loading on Firefox. Doesn't matter whether I'm on laptop Macbook Pro or iMac...or iPhone...but it loads in Safari and Google Chrome? Site is fine...document artifacts are fine...but html sits with spinning wheel?

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

Hi, It happened just days ago. The NY times does not let me read articles and tells me I am a bot not a human (I am a subscriber) or that someone is using my IP. I tried everything, clearing cache and data for everything, signed in again to no avail. I tried using a VPN to mask the IP... no success I have no problem reading it on Chrome, but I prefer Firefox. Does anyone have more ideas? The agent from NY times I contacted really was no help at all. Thanks

Cannot open AOL Mail or Facebook at times after sleeping my PC. If I revert to my Laptop or using MS Edge on my PC all is fine. I have reinstalled Firefox, but problem persists from time to time.

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.
