Upon upgrading to v140.0 on macOS Sonoma 14.3 (23D56), YouTube no longer renders.

All add-ons (ad-blockers, development tools, accessibility tools, etc.) were removed and still the same non-rendering as of this evening June 24, 2025.

I have no ability to connect to the IRS.gov account log in page. When attempting to do so, the link reverts to a maintenance page, with the hopeful message: "We apologize but there seems to be an issue completing your request. Please try again in a few minutes." An error URL is also attached.

This is not a new problem and has been ongoing for over a year. I have found several messages in the Mozilla support system describing the exact same problem from different users. There does not seem to be a fix that has been found. The information that I have found regarding the IRS website does not suggest that it will only work with Chrome or Chrome based browsers. But I can easily use the site with Edge.

There are several sites that I am unable to access with Firefox that force me to use Edge. I understand that Firefox has its security idiosyncrasies. But As this number climbs, and to include what are public facing government sites, a question I will soon ask is why use the Fireofox browser?

The Atlantic.com site says: as below, this was not the case in the past. Similarly with the NY Times I did not have this problem before I went on vacation on 10 June. Neither tech support can help. This problem does not occur if I use EDGE

Why have I been blocked?

This website is using a security service to protect itself from online attacks. The action you just performed triggered the security solution. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.

For the NY Times site, I get the following for some but not all articlesarticles

You have been blocked from The New York Times because we suspect that you're a robot. Why am I seeing this? There are a few possibilities:

   You are browsing and clicking much faster than is typical of a human being
   Something is preventing Javascript from working on your computer
   There is a bot with the same IP address as you

Does FF offer a setting to address the following two incompatibilities?

1. In the iCarol web app, as the user is approaching the timeout limit, in Chrome the browser tab flashes a warning. This does not happen in FF.

2 In the Diaplad web app, if the user needs to record a voicemail greeting, in Chrome this ability is present. In FF this ability is not present.

I've tried to book flights repeatedly online and Firefox is preventing it. How do I nknow? because I went to Safari and the bookings went straight through. Same bookings, same sites.

Hi, for some reason, I am severely restricted in size when uploading files to Facebook, with a maximum .jpg size of under 50k. I do not have this restriction in Microsoft edge, or on my phone, only on my laptop. I do not have an ad blocker installed that I am aware of. Appreciate any help. Cheers, Merv.

bought app (Gold) flightradar24 for Win 10. seems to freeze after loading an airport, no map can be displayed. Apparently can't find WebGL2. I can find the error message:

 I am using a Radeon 7600 GPU 8MB.  and Win 10 latest on Dell 7020 desktop.  where should I start?

While I am able to log into my Google account in Chrome, I am unable to do so in Firefox after the latest update. Whenever I try, I am redirected to the attached support page, which asks me to delete cookies and cache contents. Deleting those does not help.

Please help!

I'm seeing a new trend with websites that use cloudflare like restaurant accounts, Ace Hardware, and freecycle.org. Cloudflare either rejects me upon clicking it (freecycle), or it keeps cycling with its checkbox and doesn't do anything else (Hyatt). I contacted freecycle.org and they didn't know the reason. However, I can get through cloudflare using the Chrome browser. Is this fixable, because I really want to stay with Firefox? I am up to date on my drivers, Win10, and Firefox. Thanks!

Two websites I went to using Firefox today displayed the date as 6\18\2025. Today is 6\19\2025. One of them displayed the July 2025 calendar and would not allow me to click back to June. I have two Firefox Extensions on, UBlock Original and Chameleon. Any idea what may be causing this. I'm using a MAC.

Recently my HBO max started to not load on firefox... I've tried the usual suspects, cleared cache and cookies multiple times, but when trying to pick a profile, just a black screen loads. Nothing happens.

Picture below, every logged link of the site is like this, i can only access links before login, like answers/support/ads,campaigns etc. Those kind of pages load.

Also, sometimes, when accessing the site through search engines, the site loads, but on a different profile than the one I use, but when trying to switch profiles, the same thing happens again, nothing loads.

For the past several months I'm unable to Login to Mozilla Foxfire from my Desktop. The URL I'm using is: http://www.my.yahoo.com - it then switches to https://signin.att.com and I get the following message: "AT&T - It's not you, it's us. We can't complete your request right now, please try again."

Regardless how often I attempt to Login, it's useless. I'm obligated to go to Google Chrome to access my Yahoo Mail & Calendar. Have gone many years without a hitch, now this. As a long time supporter of Mozilla Foxfire I would appreciate any help y'all could offer. Thank you. esaviles@sbcglobal.net

Some web sites such as Amazon have an options bars to select items like 'review order'. When the web page first comes up, they show white in the dark bar. But Firefox is immediately changing the white to purple so that it is almost impossible to read. I haven't been able to find anything in settings to correct this. I do not have this issue when I use Chrome.

When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.

Again ONLY in FF harbor freight search function breaks when entering a search.

Yes, please don't give me the MS ctrl-alt-del type of response about cookies.... That was done many times before posting this. The website works fine in Brave. MS Edge well, let's not speak of it in public company shall we.

So, now what the heck is happening to FF???? I have contacted HF three times and they referred me to use other browsers other than FF. No, I DO NOT have multiple extensions nor themes. FF is bare bones but for uBlock. Hardware acceleration is off and MS Clear type is on. Anybody wanna fess up, who broke this????

Upon opening the NY Times website, page 1 flashes briefly. Then the screen locks in on a commercial which prevents further access to the paper. I cannot escape the ad.

This does not happen with Safari or Chrome.

Help!
