Hello

I have been using Thunderbird as my email service and not had this before. Yesterday, I had to change my password for emails with BT. I changed it on Thunderbird too but now I am receiving emails OK on Thunderbird it is refusing to send any for me and shows the above message. I can send OK from my web based BT email but prefer Thunderbird.

I haven't a clue what I need to do to solve this.

Can you please help? Please tell me is very simple steps I'm not very computer savvy.

Thank you

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.

I have imported a public key in my openpgp key-management/ In my settings of the end -to-end keys: preference of key technology: choose auto the key technology by the available keys. I have read openpgp standard supports inline en s/mime encryption but what is used by thunderbird when I choose openpgp as key encryption when i type/send an email (w/o attachment by myself). I ask it because my correspondent only decrypts inline encryption.

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?

Thunderbird continues to block my outgoing emails despite my best efforts. Please check my outgoing smpt server settings (attached) and let me know what I need to change. Thanks.

Hello all,

I had been using firefox as the standard browser for years, but since the DNS-over-HTTPS feature I have had trouble with protecting my family on the web via DNS filtering. Currently the only solution that has worked is to use a different browser (the Spin browser, for whoever is interested). I have Firefox blocked using the Android family link feature (and they can't install new apps without permission). Personally, I would love to move everyone back to Firefox, but I can't find a way to do it safely. Is there a way to effectively disable DNS-over-HTTPS such that it can't be changed (kids are pretty quick at figuring out that they can just go to the settings and figuring out that they can turn the feautre back on). A parental control feature would be ideal, so I can just set the DNS-over-HTTPS to use the family DNS filter in a way they can't turn it off. Does anyone have an helpful solution, or is Firefox dead for family protection?

Respectfully, Andrew
