Hi, it seems that my Firefox browser does not want to save a new payment method. I'm trying to access "Settings -> Privacy & Security -> Autofill" and then click on "Saved payment methods", which opens a dialog with the existing payment methods and options to remove/add/edit. I'm clicking on Add, filling-in the card details and then clicking Save, nothing happens....

I previously had a working saved payment method, but it stopped working (I think more than 6 months ago). I tried to re-enable the credit cards by setting the following configs on about:config page:

- extensions.formautofill.creditCards.available: true
- extensions.formautofill.creditCards.supportedCountries: '...,RO' -> (I was adding my country to the existing list)

After the browser restart with those new settings when I'm on a payment page, clicking on a credit card field will show the saved credit card but if I click on it, it will not fill the details. And also trying to save a new card, manually as described previously in this message, or by the automatically prompt to save a new card after a successful payment was done. Both methods failed on me but with no error (I cannot see the saved payment on the list).

I tried removing the existing saved card, it worked removing it, but the add is still not working.

I also tried restarting in save mode, launching Firefox in a separate profile and added my country on the creditCards config for supportedCountries to show the "Saved payment methods" button on new profile, and it did not change anything.

I'm thinking there is a missing permission somewhere on the disk but I don't know where is the payment data stored on disk.

I would really appreciate any help on this.

PS: Check the attached pic to see the payment add and clicking the save button does nothing (also there are no validation errors). And the other: FF version, OS, troubleshooting info.

I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

Is there a way to turn off tracking URL fragment insertion from the release notes page when clicking "What's New" in the Firefox update modal?

When I click "What's New" in this modal (see Screenshot 1), it loads the release notes page for my current version (although it really should load the release notes page for the version it wants me to upgrade to, but that's another issue altogether), and inserts a bunch of tracking URI fragments onto the URL (see Screenshot 2).

Is there a way (in Settings, about:config, Windows Registry, etc.) to disable that fragment insertion?

Hello,

I am trying to force two or three websites to detect my timezone as UTC, even though my local system time is not UTC. I figured out how to do this with ALL sites by setting privacy.fingerprintingProtection to "true" and entering "+JSDateTimeUTC" in privacy.fingerprintingProtection.overrides in about:config.

Now according to docs, privacy.fingerprintingProtection.granularOverrides "can be used to add or remove features on a domain granular level if privacy.fingerprintingProtection is enabled," but I can't figure out how to get it working.

Any input is appreciated.

I simply want to use a password to open Firefox. I don't want to set up Firefox sync. How can I set up a simple password as permission to open Firefox without accessing sync?

The story is when I accidentally clicked on a sick video, YouTube start to recommend me similar sick videos.

So my question is how does YouTube get my identity?

I'm not logged in. my profile is actually a snapshot, so when I restart Firefox, it go back to the snapshot. I even restarted my ISP router to get a new IP address. This did not work.

Only when I create a new profile with "firefox -P" does YouTube start to see me as a new person.

So how does YouTube identify my Firefox profile? I don't think it's in the https request headers. Weird.

Hi I have been using firefox on linux for a while without updating it. We are artsellers and I used to be able to log in and out of an artplatform without any problems. It's now been a few weeks since logging out is not possible any more on this platform which means that I am constantly logged in which I really do not want. The menu does not work anymore on this side whereas it works with other browers. I already contacted the platform. They cannot do anything about it themselves and asked me to contact your team. Please help. Thank you Best regards from Germany C. Marsac

I have a unique annoyance wherein I use a considerably long email address for many sites. I've gotten tired of typing it out whenever it comes up and wish for it to be preserved as an autofill across all sites so I no longer have to, similar to how your phone may suggest your email address in autocomplete.

Unfortunately, as far as I can tell, you can only manually add autofills for specific sites and with password attached. So my question is, is there a way to make the address be a suggested autofill on username/email address boxes across all sites?

(not interested in having form history saved, just want this one specific form entry)

Firefox removes the exceptions after every update and they have to be manually re-added. This is a very frustrating user experience. Can you please help me identify if this is an issue with Firefox that can be updated or is it an issue with some setting I have setup.

Exceptions that get reset - Cookies and Site Data, Pop-ups, Add-ons, etc.

Permissions that get reset - All of them Location, Camera, Microphone, etc.

• Side note, the Troubleshooting Information section below has a link to share data, that link does not open in a new window. It opened in this same window, erasing all the content I had typed up the first time.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

Firefox 125.0.1 update breaks all self signed certificates

After the latest auto update I can no longer access any of my management screens on my private network with self signed certificates. This is a real problem. I have attached a couple error screen grabs, but ALL of themn are the same. The information link says there is no workaround!

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

I have included a website on the list of exceptions for deleting cookies when Firefox is closed. When I go to the website the icons on Firefox for it show "enhanced tracking protection off" and "You have granted this website additional permissions". This website uses cookies to recognize my computer and not to require a one time password. However, when I close Firefox despite the fact that the website is on the exception list, cookies are deleted and I have to keep re-entering the one time password. I did turn of the checkbox for deleting cookies when Firefox is closed and now I am no longer asked to enter the OTP after Firefox is closed.

I assume this is a bug. Does anyone else experience similar issues? Is anything I can do about it and be able to use the exception list as intended?

Thanks.

hello, I've been trying to follow Firefox's official guide in the docs and ready 3rd party articles in order to enable payment method auto-fill in Firefox. however, this section seems to be missing from my settings page.

under Privacy and Security, I cannot find anything to do with saved payment methods or the checkbox to enable payment method auto-fill.

how can I resolve it?

v155.9.1esr Debian 12

I'm testing different Debian 12 on multiple VMs, it came to my surprise to see that my VPN hash I used on a website the day before was saved by Firefox on the new VM.

The Sync was on but then which one saved my form (hash)?

1. Numbered list item Logins & Passwords ? note: The hash was not a login but a form. If Firefox saves all the form, you should explicitly rename Logins by any forms/inputs.
2. Numbered list item History? note: I hope this is only URLs.

If Firefox is savings "forms" (input fields) not just "logins" then it should be explicitly written. Is it an expected behavior?

I go to about:memory > Save memory reports - Measure and save and then view the output, a report called memory-report.json.

In this report I see approximately 30 blocks of text, each of which contains approximately 50 to 100 website URLs. Several blocks contain only porn URLs. I have viewed porn, but only in Google Images; I don't visit the websites.

Why is this information being stored by Firefox?

Note: my Firefox is set to Delete cookies and site data when Firefox is closed. However, even after closing and opening Firefox, all the information is still in the report.

A sample of two of these blocks of text is attached.

Hi, Firstly I apologize because I'm not very tech savvy. My firefox browser has been taking ages to load. I've tried various 'fixes' over the last week or so and they don't work for long. I'm going down the 'try this' list and am at the 'clear junk in manage data' suggestion. Someone else had success with getting rid of a load of youtube saved junk. I'm in the Cookie and Site Data area, it says it's using 793mb of disc space yet when I tap on 'manage data' to try and clear stuff that area shows up as empty. I've searched but can't locate how to fix this issue. Or I might be missing something completely obvious. :/

My memory, and health, is not great so if possible I really don't want to resort to clearing everything and having to re-add log ins etc.

Does anyone know how to fix this please?

Thank you!

Having tried all pointers to how to display this data, I give up and present my case here: In a banking app, the login field is blank and requires me to enter the correct Login ID. This works fine. However, if I double click on that field, an option is displayed, happening to be my email address, which will not work in this case; a numeric value is required.

So, knowing a prompt is enabled, I have entirely failed to get 'it' to save the correct ID. I have also find a place in Firefox settings where I can see and modify the value that comes up. I do however remember doing exactly that for some other site.

So, as I have said, I cannot find this in the Passwords nor the Settings pages. What am I missing?

Help would be much appreciated.
