Firefox: 142.0.1 (64-bit) macOS: Sequoia 15.6.1 (24G90)

A repeat of a problem I was having a couple of months ago. I go to the reddit website and login with no problems but when I try to comment or load specific threads I get the attached warning come up:

"! Your request has been blocked by network security. Please try to login with your Redit account."

Which doesn't make sense as I'm already logged in. Last time it seemed to clear after 24 hours or so although not because of anything I did as far as I'm aware.

1. Started Firefox in Troubleshoot Mode - problem remains … 2. Cleared Firefox Cache/Cookies and restarted Firefox - problem remains … 3. Shutdown and restarted iMac - problem remains … 4. Problem not happening with Safari or DuckDuckGo browsers … 5. Checked macOS Local Network security. Firefox has access but turned off access and turned back on, restarted iMac - problem remains …

Since upgrading to Windows 10, I can only access my Yahoo email using Microsoft Edge. When I try to access in Firefox or Google Chrome, my access is denied. I've tried clearing cookies, browser history, rebooting my router, etc. Any ideas I can try?

Since the FireFox Desktop update over a month ago (and subsequent patches, currently on Version 142.0.1 (64-bit)), every time I type an email using AOL webmail in the FireFox browser using my Windows 10 Dell desktop, I can only type a few characters before the cursor jumps off the line I am typing and I have to use the mouse to reclick where it stopped typing to again try to retype. This can happen multiple times sometimes as a short as typing only one character before the cursor jumps and I cannot further type. It has now become soooo annoying that I am thinking of changing browers after having using FireFox for as long as I can remember. This does NOT occur when using any other browser, including Edge and Chrome, so it is not to AOL webmail app but rather something in FireFox.

Has anyone else reported the same? Can anything be done to fix this problem before I jump ship to Edge or Chrome on a permanent basis?

Before I used Firefox for browsing the web, but now when I try to go to indeed.com to search for a job all I get is a white screen, or when I go to pluto.tv to stream TV all I get is a black screen, can you please check what's going on and fix it, so I can start using Firefox again as my default browser.

Thanks.

I can no longer sign in to sites that seem to use microsoft azure for authentication. Including: www.comed.com people's gas through https://login.wecenergygroup.com www.athletico.com which goes to https://myathleticob2cprd.b2clogin.com

All of them return a page that just says "Bad Request" after I enter my credentials and proceed.

I normally use AdBlockPlus and NoScript but I have both of those disabled.

I can login through chromium browsers.

Are others able to use those sites? Any suggestions?

Hello.

I 'might' be missing a detail but there is no 'X,' in the top right corner, when viewing Google Reviews.

Clearing cookies, closing and reopening the browser, and rebooting the PC are not successful.

.: 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.

One of my permanent tabs, www.nytimes.com, automatically refreshes the page every so often (5-10 minutes) when using the Windows version. However, the page remains static in the MacOS version -- the only way to update the page is to do so manually. I've looked for a setting, thinking maybe I set up something differently on the two browsers, but can't find anything. If it's not me, it would be great if the Mac version auto-refreshed the page just like the Windows version does!

Since the update to 142, on pretty much every site it keeps jumping back to the top of the page. Happens on a lot of sites. For some reason, if I select some text at the top of the page it seems to stop this. A lot of people may not have discovered this. Mozilla just needs to fix it. I am using Ubuntu 24.04. Been using Firefox for many years. Never seen this before.

when i'm browsing youtube shorts on my windows based laptop, it will not stop scrolling. N0 problems on regular browsing or scrolling, only on SHORTS.

When I use Google Chrome, youtube shorts functions properly.

I have asked this question before and followed ALL recommendations to no avail. I received no other suggestions to now, nearly a year later I am asking this question again. I had to stop using my favorite browser because of this. You all used to help your users but alas, no more. Here is a link to my previous question and then below is my present question;

I am running a fully updated Windows 11 computer. I have 4 fully up to date browsers; Vivaldi 7.5.3735.66 (Stable channel) (64-bit); EDGE Version 139.0.3405.125 (Official build) (64-bit); DuckDuckGo version 0.126.3; and Firefox 142.01. I play Bejeweled Blitz on FaceBook. The game works perfectly on all browsers EXCEPT Firefox. When I try to play on Firefox I get a message that says I must "upgrade to the latest version of Flash:. There is NO flash anymore. Why am I getting this message on Firefox but the game works just fine on all other browsers?

When I have attempted to log in to my MyPoints and my Entergy electricity account to pay my bill. I can not log in after the previous update. I was able to log in to my Entergy account on 08/22/2025 to pay one of our power bills. This was accomplished with out issue. When I went to log in to my Entergy account on 08/29/2025. The User name and password screen cleared correctly. The next step was for a 2ed step verification with a 6 digit code sent to my cell phone. This did not work at all. I tried several times after restarting my phone , computer, phone and computer with the same result.

Hi Moneysavingexpert is a website that sends out emails with links for different sections of its website. I can only go to the main page, when I click other links in the email, or on the website main page, it just returns me to the main web page. I am not having issues with any other websites and I have turned some ad blockers in case it was them but I still have the problem. No one else has reported this problem on the website so I am guessing it must be something to do with my settings....

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.
