Today (4/27/2026) I am suddenly unable to log in to My Account on various websites (eMail, grocery store...) The business page opens but when I try to go to the account login page, I either get a blank page or the page spins and spins and never goes to the login page. I am able to get to the logins on Safari. I've cleared cache and cookies, and closed out of Firefox and reopened.

.

If the VPN is open in one user account on a given computer, is it functioning on all accounts on this computer? I have difficulty turning the VPN on when using one user account if it is already on in another user account. Seems to be a conflict and I don't know if it is even necessary.

I HAVE FINISHED SET-UP BUT I AM STILL BEING PROMPTED TO FINISH, WHY FIREFOX IS MY DEFUALT BROWSER IHAVE IMPORTEDTED SETTINGS AND MY SYNC IS COMPLETE UNDER MY PROFILE

What happened: 1) I wanted to create a Passkey for a website and store it in Bitwarden. 2) Bitwarden pop-up opened, but while exploring the options, I accidentally clicked on the option "Use your device or hardware key: Always for this website". 3) Windows Defender dialog popped up with the options "iPhone, iPad or Android device" and "Security key" 4) I backed out of the dialog window 5) I clicked the button to create a Passkey again but going forward only the Windows Defender pop-up appears

The problem: I now cannot create a Passkey to store in Bitwarden on a specific website, because I accidentally clicked on "Use your device or hardware key: Always for this website".

What I've tried that didn't work: - looking through Bitwarden settings - deleting Firefox cookies - doing the same thing in Private Browsing - asking AI and looking through about:config, about:preferences and about:logins, as well as trying to find profile files related to webauth

Found workaround: - creating the Passkey from a different Mozilla profile

I would still very much like to be able to undo the "Always for this website". Is there a way to do that? (Attached images were captured later when recreating the situation.)

This morning I tried to sign in to my Credit Union account. I clicked on my sign-in name, nothing there. I went to my password for my Credit Union account & the entire password manager listing is blank. There are no accounts listed at all. Have someone stolen my information? Did I press something wrong to delete them? I'm 78 years old & not very computer knowledgeable. I have used Firefox for maybe 15 years old & have never had any kind of problem before. Kind I restore this part of my account?

Since the update I performed today, 4/27/26, I am unable to upload files to my NAS via the Firefox web browser on a Windows 11 PC. I can still do it via the Google Chrome browser so I am not completely crippled, but it would be nice if I could still use Firefox for this work. Any suggestions on how to fix this, or will it require the software itself to be fixed?

Fire fox is automatically playing videos/sound or both if I click on a tab that has that or also in facebook, etc. How do I stop this? I want to be able to click play when I want to hear/see something.

Hi All,

I have tried the new free browser VPN however it does not load pages if I am using a custom DNS (Quad9) and have DNS over HTTPS enabled. Is this expected behaviour and just a limitation of the VPN?

Any advice would be much appreciated.

I'm using Firefox v126. I'm searching through the add-ons trying to find a few that I like and most don't work with my older version of Firefox. So I click into the version history of the add-on and find an older version of the add-on that will work with the version of Firefox I am running. Except... I click it and I get:

"The add-on downloaded from this site could not be installed because it appears to be corrupt."

say what? ok maybe a fluke, so I click on through, older version, older version, still old version. All give me the same error. Okay, maybe its just the add-on, no, its literally any older version of any add-on.

No way all those versions of add-ons are "corrupt." I can download the .xpi, rename to .zip and view the contents. Anyone run into this particular problem before and if so, how did you fix it? I'm keen to keep v126 of Firefox and would like to use the add-ons that I like to work with it.

My Dell Precision Laptop from 2019 runs a frequently updated Ubuntu 24.04. About one or two weeks ago, after one of the latest Firefox updates, i noticed that video streaming produces rectangular flickering in rapid sweeps. ( Also fast scrolling large text websites produces similar flickering, I think I would have noticed it before...) . If you detected it once, you see it always again... :-( First I fiddled around with the nvidia settings because the driver was also recently updated, without much success. Playing locally stored videos, e.g. with VLC media player, still works fine, so the nvidia driver is not the problem i think. Yesterday I installed Chromium and the video performance is fine! As good as with firefox some weeks ago! So it must be one of the latest updates, that causes the problem. Generally I like firefox more than chromium. I like the control you have, e.g. via Add ons.. So I hope that the firefox performance will increase again... Thank you for firefox! Florian Mengedoht

"Login" button does not respond to click after "Login ID" and "Password" input anymore after Apr 21 on Firefox.. Unable to access emails. https://login.netvigator.com/ Can access same website from Chrome on mini iPad or same notebook though.. How can I resolve the problem on Firefox?? Thank you.

You say, "Some essential Mozilla services are excluded from VPN routing to ensure sign-in, VPN reconnection, and screens needed to sign in for public Wi-Fi work properly. All other browsing activity in Firefox remains protected when the VPN is on."

How then am I protected in any kind of secure way?

All it would take is the Mozilla services using my public IP to lose my browsing protection. How are those connections secured to protect my identity from being exposed once the VPN is enabled and even after the VPN is enabled?

If the public IP can be discovered at sign-in, re-connections, and public Wi-Fi connections before the VPN is enabled, then that same public IP can be traced through internal logs to uncover all the VPN activity done after sign-in, re-connections, and public Wi-Fi access. So, how exactly can I trust the VPN protects my activity at all?

I'm just curious how you setup any protection prior to the VPN being enabled? I'm a former IT Network Specialist I had my CISCO CCNA certificate (Worked in school districts who wouldn't pay for additional certificates so I did all the study work and practice testing up to the CCNP certification just could never afford to take any of the exams beyond the CCNA). So, when I see these additional things like your 50 GB of free browser VPN and read how it works I get curious about the actual protections being provided. Are the people more vulnerable than they may be led to believe?

websites are being blocked when I click on links from my email account and I don't know why but I also want it stopped the websites are Stage32.com and https://course.fp-platform.online/learn/hRpTYcFi2UyZKzLm2gaOHg/theory

I have configured advance tracking protection and set all variables to true in the configuration editor except "privacy.resistFingerprinting.jsmloglevel" which is set to "warn". I still have a unique fingerprint. Other than starting over is there anything else I can do?

Symptoms: Gmail rendered on a half window, Youtube video boxes flickering, weird rendering stuff, is this my ancient GPU card? Other browsers work fine. Is it firefox, my Win11 machine, the old GPU? I don't want to migrate to another browser, but this is getting untenable!

I enabled the Firefox browser VPN as a test and then disabled it, after the Google search no longer worked.

Error says Google.com is unavailable, can't connect to servers etc.

Any ideas how to fix it ?
