I have had zero problems logging in to eBay. That is, until, August 14, 2025. Now, I am getting an error stating that their server is down. I have cleaned my cache, cookies, turned off all of my Ad Blocking extensions, and I am still experiencing problems. Now, I have absolutely no problems logging into eBay via Microsoft Edge. As for security softer, all I am using is Windows Defender. What is going on? Please assist. I look forward to hearing from you and time is of the essence. Thank you.

I have so much trouble with payment sites. Showing the wrong amount, or just plain doesn't work, then I go over to Chrome, and it's fine. Why is this?

I have Bitwarden Password Manager, Duck Duck Go Privacy Essentials, Facebook Container, and Tab Session Manager extensions.

I keep getting "something went wrong" on this site: https://signup.grasshopper.com/billing even though it does not point to a specific field, and I have checked all the fields.

I have had similar things happen several times recently, sorry, I don't remember the details. I know I tried to purchase something from loft.com, and there should have been a discount, and it was not showing up, but if I went to Chrome, it worked fine.

Not sure if this is the correct topic selection but nothing offered above really fits.

I tried to sign into my Allstate.com account today and kept getting error messages.

I called their tech department and they told me that Firefox has been notified a long time ago about this issue but has done nothing about it. I was told to use my email account instead of my user ID to get into my account via Firefox, but that if I do it that way, some functions still won't work on Firefox.

I was told that my Safari browser would work, and it does.

Not sure why Firefox refuses to fix this. This is crazy. I've also had problems signing in some other companies with Firefox recently where it used to work fine. It looks like they are just not keeping up with technology. I have the latest Firefox browser for my Macbook, but as companies update their sites, Firefox is staying behind. I prefer Firefox because of things like uBlock Origin, Enhancer for YouTube, and YouTube Watchmarker which I love, but I've had to use Safari more and more because of this issue.

Exactly how does one let Firefox tech know these things. They don't provide anyway to contact them which doesn't look good.

Firefox connection fails on my mac cleared everything used troubleshooting mode works on windows iphone. I used wireshark and there is no attempt to contact the failing server only see udp broadcast from server. Safari works find DNS is fine cleared everything. Only thing I have not done is reinstall. No trouble connecting to other websites, this is the only one. I ran a virus scan at a loss.

前提として、139.0.4 では発生せず、140.0.2 では発生することが確認できました。（この間にイベント発火に関する修正が入っている？）

onloadイベントやloadイベントが意図しないタイミングで発火してしまいます。 そのため、動作すべきではないjavascriptが動作してしまいシステムに影響が出ている状況です。

Chrome/Edgeでは発火しないタイミングとなっていて、かつfirefox ver.139.0.4でも該当の問題は発生していませんでした。

上記のようになってしまう理由が分かれば教えて頂けないでしょうか？

for some time now I've been unable to sign into my account at "spectrum.net" while using Firefox, and receive an error message "IDID 4009". I do not have any problem signing into this account using Microsoft Edge.

There are several sites (i.e., Hallmark.com or BlueMountain.com that I am not able to get into thru Firefox. I am able to get into them thru Chrome. Why is this and how do I fix it? I am not completely sure how to navigate thru the Mozilla items and what they ask me to do.

Thanks,

Starting with several updates in recent weeks, that were coming fast and furious, etrade.com will not refresh. They have an update button but nothing happens. "F5" does nothing either. All other websites work.

I figured you must know, that's why there have been several updates in succession.

I have been using Firefox for 2 years on my Mac Air with Nord VPN to watch BBC IPlayer (UK connection) then about a week ago it would fail to recognise that I was in UK. I changed browser to Safari and it all works. I would prefer to continue to use Firefox.

Any thing I can do.

Twitterで使用されている「t.co」等の短縮URLにアクセス出来ず、「アクセスしようとしているサイトを見つけられません」とエラーが表示されます。 他のブラウザだとアクセス出来る為、Firefoxの設定の問題だと思うのですが、解消方法が分かりません。 解消方法をご存知な方はいらっしゃいますでしょうか。

I am a user over at the Arcamax website I use it nightly to read the comics section for the last two days i keep getting an error message .

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I went into my system cleared out the cookies for that website still cant get into the website I switch over to Chrome and it works fine but slow as molasses.

My yahoo mail account exceeded its' maximum storage. I upgraded and since then yahoo does not work on this computer. My yahoo mail account works fine on my laptop. Firefox was also upgraded along with windows 10

The Atlassian Confluence "Audio Briefings" icon is consistently greyed out using the Firefox web browser (my browser of choice). How can this be enabled? This is not an issue using the Chrome and Safari web browsers on the same content. I have verified Autoplay, Microphone and Speaker settings and ensured the domain has been added to the list of exceptions to the default (which is more restrictive). Hardware and WebGL are both enabled as well. I would think Firefox would want to ensure the browser is compatible with major business applications such as those by Atlassian.
