After recent Firefox update in v 154, saved passwords do not auto-fill in all websites. Actually, not even the username is loaded. I tried to open in troubleshoot mode and didn't work too. I tried to log out and re-login and fixed for a while only. Then same issue re-occurred. In websites where I have multiple accounts it's too hard to find the proper one. In the Settings > Passwords everything is enabled.

I'm finding more and more sites no longer work using Firefox. I've confirmed all software is up to date, and tried different settings such as turning off ad , tracker and fingerprinting protections, but nothing works. Even sites at which I have an account have stopped working. Sometimes I can still log in to the account, on others I can't even do that. If I can log in, using the account for what it's intended such as searching for and saving lists of things or following links to saved items doesn't work. I value Firefox for it's security and privacy features, and being able to sync saved information in the account and across devices, but if a site won't all that benefit disappears.

I've seen this on a few sites and it sounds like this person also experienced this. It happens on Linux and Window. I don't think it's a new bug/behavior.

I'll use vanguard.com as an example.

1. Visit investor.vanguard.com site. Click that you'd like to log on. 2. I'll be placed on a login.vanguard.com page that displays a Username field and a Password field. Because I've logged in before, those fields are yellow and filled in with the proper values. (In the case of the password field, it's all stars, but when I click to reveal the password, it's the correct password.) 3. Click on the "Log In". 4. The browser rerenders the page claiming that the userid or password is wrong.

But if I follow the above steps, but add a step:

2.5. I slightly edit both (one is not sufficient) fields, removing a character and putting it back in so the values are edited but not changed. As I do this the fields become white instead of yellow.

Now when I reach step (4), I'm actually logged in without complaints.

The underlying AJAX request is pretty cryptic, so I can't quickly spot/debug what happens at that level, but I assume the page is not passing the field values visible as yellow. on the page.

Am I misunderstanding how the yellow auto-fill works? (On most sites it works as I expected and no reediting the autofilled fields is necessary.)

Can this be fixed or should I put up with it?

Firefox is screwing my display with a screen logging warning message. Removal instructions are 100% useless.

This is so annoying. I’m sure its simples if you’re a techhie, but for muppets its hopeless, I’m desperate for a solution as i cant use Firefox now

I regularly login, via Firefox, to access NAB (National Australia Bank) accounts, through their Internet Banking selection. Over the last week/10 days this login has not worked - I get a (NAB bank) message saying "Something went wrong / try again later". Trying again later does not work. (pic.1)

I rang the bank and spent some time trying to sort out the issue. Suggestion to get a new browser page via [Ctl][Shift][P] helped part way. I did get SOME of the new "logged-in page" showing, but not all the account details - blank grey lines were fading in & out like it was waiting to load information. (pic.2)

The bank suggested trying another browser, so I tried using MS Edge and was Successful. The bank has recently updated the "look" of the screen (home page) that appears once logged in. Could there be an issue between Firefox and these new pages ?

I would prefer to be able to keep using Firefox and not Edge.

Thankyou

Kept getting messages that Firefox is unresponsive during use. Has now stopped all together. Uninstalled and reloaded, got a welcome to Firefox message then it went unresponsive again. Now a double click on the App to start does nothing.

Hi Community,

I’ve used Firefox for over 20 years and it’s always been my main browser, but since updating my Mac to macOS 27, Firefox has become unusable with one of my essential web apps (FlightLogger). The first page after logging in loads normally, but any click or navigation after that fails. The header stays visible, the rest of the page stays blank, and clicking links only adds a “#” to the URL with no content loading.

Safari works perfectly on the same machine and same network.

In Firefox’s console, every JavaScript file coming from CloudFront fails with “CORS request did not succeed (Status code: null)”, and I also see repeated “A ServiceWorker intercepted the request and encountered an unexpected error” messages. Module scripts are also blocked with “Module source URI is not allowed in this document.”

To rule out local issues, I’ve already reinstalled Firefox, created new profiles, cleared all caches/cookies/service workers, disabled all extensions, disabled DNS‑over‑HTTPS, disabled Enhanced Tracking Protection, reset macOS network settings, checked proxy settings, and tried different networks. The problem persists even with a completely fresh Firefox install and profile.

This started immediately after upgrading to macOS 27, and only affects Firefox. Safari loads the same CloudFront assets without any issue. It looks like Firefox can load the initial HTML but cannot fetch any CloudFront‑hosted JavaScript modules, which breaks navigation entirely.

Has anyone else seen this after updating to macOS 27, or found a workaround? I’d really like to keep using Firefox as my main browser.

Thanks in advance

Alors que je n’ai pas demandé de mise à jour une nouvelle page Firefox est apparu sur mon ordinateur, iMac Apple et tous les marque-pages personnelles et autres ont disparu, Que faire pour opérer la totalité de mon ancienne version dans ce nouveau navigateur,

Hello,

I am experiencing a serious display flickering/refresh issue in Firefox when opening DRM streaming websites such as Netflix, Amazon Prime Video and HBO/Max.

My system:

GPU: NVIDIA GeForce RTX 3080 Monitor: LG 34GL750 Windows PC Latest NVIDIA driver installed

The problem:

When I open Netflix/Prime Video/HBO/Max in Firefox, the display repeatedly flickers or appears to restart. There is no "No Signal" message from the monitor. Closing Firefox sometimes makes the display recover. Unplugging/reconnecting the display cable has sometimes been necessary. The same problem does NOT occur in Brave, using the same PC, GPU, monitor and cable.

Troubleshooting already performed:

Updated to the latest NVIDIA driver, including the recent driver update that mentioned display-related issues. Tried a different display cable. Disabled Firefox hardware acceleration. Tested with Firefox Troubleshooting Mode — the problem still occurs. Disabled/enabled Firefox DRM/Widevine — the problem still occurs. Tested with a completely new Firefox profile — the problem still occurs. Disabled G-SYNC — the problem still occurs. Disabled uBlock — the problem still occurs. Checked about — there are no recent crash reports related to the problem.

Firefox about information:

GPU #1: NVIDIA GeForce RTX 3080 Active: Yes

In my normal Firefox profile: Compositing: WebRender (Software) HARDWARE_VIDEO_DECODING: runtime: unavailable Requires texture sharing Blocklisted; failure code FEATURE_FAILURE_BROKEN_TEXTURE_SHARING

In a completely new Firefox profile: HARDWARE_VIDEO_DECODING: default: available

However, the display problem still occurs in the new profile.

Thank you.

Warum muss ich immer wieder die Surfdaten löschen damit ich die Seite meines Routers öffnen kann ? Nur dann funktioniert eigenartiger Weise mein Passwort. Es ist die Seite:http://192.168.8.1/#/home zu meinem Huawei B636 Anmeldung. Mein Firefox ist auf aktuellem Stand. Bitte um Info bzw. Abhilfe

When I try to go to Google's website, I get this message:

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Error Code: PR_CONNECT_RESET_ERROR

The same thing happens with YouTube TV. My Bitdefender also flagged it as a suspicious page.
