Firefox Community Forum

I could not get into my Fidelity Investments account today. (I signed up last week using same computer w/Firefox) I got to the login page but Fidelity gave me a "can't complete at this time, try again" notice. So I called them up and they suggested I use chrome. I don't want to use chrome. I tried reentering with the VPN off and on. No go.

Hello,

I have been testing all browsers I use (Firefox, Chrome, Edge) on Cloudflare Post-Quantum Key Agreement to verify PQC support. They all support the X25519MLKEM768 hybrid scheme (i.e. Cloudflare web page returns "You are using X25519MLKEM768 which is post-quantum secure").

The issue: When I run the test in Firefox multiple times by doing repeated hard refreshes (Ctrl+Shift+R), quite often the result is "You are using X25519 which is not post-quantum secure". Sometimes the very first run after opening Firefox gives the X25519 (failing) result. "Often" varies. Sometimes it's around 10 fails out of 50 tests, other times it's 1 out of 50. It seems random.

I have read that sometimes networking equipment or even ISPs can be the cause of PQC requests falling back to non-PQC due to the long keys in PQC, but I do not see this intermittent issue with Chrome or Edge on the same computer/network/ISP as Firefox. I have not seen a single failure so far on those two browsers. The only variable I am aware of is the web browser.

I also tried connecting to a cellular hotspot as well as disabling my Norton 360 firewall and the results are the same as above.

Looking for help to resolve this issue. Thanks.

The title sums it up. On May 25, 2026 Round Cube email will not allow me to re-enable Dark Reader. It had been working up to that point. I disabled Dark Reader just to see my email without it, then attempted to enable it. Can not. Interestingly, Round Cube in Microsoft Edge will still allow Dark Reader. So, Firefox Nightly the issue?

Hello. I'm not sure if this is the correct place to bring up my concern. So, I apologize in advance if it's not.

I volunteer with a domestic violence organization. The group's website (180NJ.org) has a "panic button" function where a DV victim could bail out instantly if their abuser confronts them. When you hit the "Safety Exit" button, it changes the page to weather.com and Google comes up in a new tab. This is so an abuser can't see what the victim was looking at, for the victim's safety. When using Chrome and Edge, the DV site is removed from the History. When using Firefox, it is not removed from the History. I've brought this to the attention of the organization's IT people and was told that this is probably due to differences in the browsers themselves.

I'm not an IT person myself and have no idea what's involved in all of this. But, I just wanted to bring it to your attention, in case it's something you can work out. Thank you.

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

I love you Firefox but what gives you the right to change/mess with my settings on my home page and make it difficult for non technical user to change back to preferred look???????? Why do you do it?

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

I mistakenly agreed to update Firefox to V 151.02. Once again I regret it but there is no way to turn off the stupid prompt windows telling to you to update.

Now when i open a new tab , the wasted space on my COMPUTER screen is incredible. Instead of the old format withm3 wide "columns" of suggested stories/articles it is now one prominent, and a narrow list of only two wide. requiring me to scroll down twice as far as I used to. I have large white blank unused screen space being wasted. It seems to be optimized for only people who use their narrow phone screens only in portrait mode.

I hate the random useless changes that affect my normal everyday usage of the browser, without any options to go back to old formats or settings.

I am actually thinking of switching to EDGE, or Chrome on my Windows computers.

Wish Mitchel was still my student as I would vocalize my complaint directly to them. But that was back in the days when it was a responsive community .org. Not the now privatized for profit entity that Mozilla has become.

As i had to create another useless account just to submit any sort of feedback, watch as I get constant useless emails with no relevance to anything in my life, as all i wanted was a simple way to make my screen the same as it was for the past versions

Animated icons worked in the previous versions and I like them. It was also a way in which Firefox differentiated itself from the Gobble/Microslop browsers.

Is there a way for me to enable animated icon viewing in the latest browser versions so I can continue to view them? I really hate that animated web page icons now appear as static icons. Hate, hate, hate.

I use Firefox for viewing my Rogers/Yahoo web mail in an open tab. I have granted Yahoo mail permission to send notifications and I get a Windows 11 toast notifications when there is a new email in my inbox.

The problem that I cannot figure out is that the notifications take the form of "X undefined", where X is the sender's name. There is something that is appending the word undefined to the sender's name in the notification. I also note that these notifications are "sticky", that is, they remain visible until dismissed. I would prefer that they dismiss after a few seconds and remain in the notification centre.

I am using Windows 11 Home edition with the latest updates.

WELL BEFORE BROWSING AND SAY LOOKING AT IMAGES OF SAY THE BEATLES. I WANT TO SEE ONE PHOTO SO I LEFT CLICK. ALL IT DOES IS GO BACK TO ORIGINAL SCREEN. WHEREAS FOR YEARS THE PHOTO WOULD POP UP. THAT'S MY ISSUE?

Whenever I open Firefox in my laptop, many pop up news snippets start appearing. It disturbs me and intrudes into my work. Please stop all pop ups and notifications. Thank you.
