Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

Firefox is set to remember history, but every time I close it and re-open it, links in websites that once had purple text is now back to white, so I don't know what link I'm on, Firefox remembers this through history saved, why does it reset back to white text? Does it have something to do with bitdefender or bitdefender VPN? Can anyone else test thie out with firefox and bitdefenders full security on? Firefox is set to save everything by the way. Only started happening after installing bitdefender.

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

Hi,

Since recent updates to Firefox I get a purple pop-up listing Trackers at the bottom right of my screen every time I open a new webpage. I'm happy with my PC security settings and have good protection software running - but this pop-up listing Trackers is becoming a nuisance.

Is there a way to stop Firefox displaying the Tracker notification pop-ups whilst still intercepting and blocking them in accordance with my security settings?

I see that other users have asked the same question, but it does not seem to have been answered yet.

Thanks,

Peter

i want to disable my spamblocker/ junk mail detector in firefox ..... it keeps sending legit emails to the spam file no matter how i adjust the junkmail settings....is there a way to just turn the spam/junk detector off altogether?

i already have spam detector through my cPanel at my webhost and another junkmail detector in antivirus/malware program on my desktop

i don't need firefox diverting legit emails that get through the earlier detectors.

I changed the password of one of my emails when trying to configure it for my phone. I forgot that it was set to 0auth2. So now I have changed the password and can open the Gmail, account online OK, but I can't find how to go back to the 0auth2 password. 0auth2 is still set in Thunderbird but I have no idea what the old 0auth2 code was. How can I update it to work again?

We downloaded the GPO Templates for AD and looking to customize Firefox.

We would like to disable Forms and Autofill: Autofill addresses Autofill credit cards

Also would like to lock down so they can't reenable if possible.

We would like to do this all through GPOs if possible. I found these in the about:config: extensions.formautofill.addresses.enabled extensions.formautofill.creditCards.enabled

But again want to do through the GPO. Is this possible?

Side note while working on GPOs, I set Exceptions for the popup blocker and they are not showing up in the browser. I also filled out to remove Search Engines but they all still appear in the browsers. These two GPO settings don't appear to be working.

I am an admin of some servers, i modify the proxy settings of firefox in a GPO, and it works, but now ont thing is that users can modify the settings of "No proxy for" in Connection Settings, then add the urls, then users can access to any web site which they want to, is there a method to disable this? thanks.

I use/like the randomly-generated 'strong' password feature, but is there a setting/option to have it include one or more special character(s)? So many sites nowadays require one, and VERY few *prohibit* them. I know I can 'substitute' one in there, but I'm VERY lazy! Thanks.

Hello,

I have been using Thunderbird for years to collect all emails in one place with out issue. In the last few days authentication has started failing. It started on one gmail account prompting for a password. When I enter the password it is rejected. A second GMail account is now doing the same and one of my Yahoo accounts is now doing it too.

I can still access the accounts on my phone using Oauth2.

Nothing I have tried fixes it. I am in danger of losing access to all my of my email accounts on windows.

What is going wrong?

Hi there,

Using up to date Firefox on a Mac, London UK. Recently returned from travel in Japan. The bank cards auto-fill stopped working & Auto-fill does not appear in Privacy Settings (it is not there – no need to request a check please:)?

Spent 2 hours on Mozilla support/community etc. No answers – including 'make a new profile'...(& why - won' that affect history etc)?

Would be very grateful for any help please?

With thanks,

Alex

I am running Firefox 118.0.2 64 bit on windows 10 22H2. For one particular website I get a 403 error on Firefox, the site opens normally on Edge. I do not have any add ons or extensions that block websites. I have cleared cache and cookies and tried to open the site in troubleshooting mode, no luck. I have also disabled BitDefender, same results. Any suggestions are appreciated.

Hi, I have configured 2 accounts for E2EE using OpenPGP. I can send signed emails &/or encrypted messages between the 2 accounts. However, if I send a "normal" message i.e. no signing & no encryption selected, it arrives as not signed (correct), but encrypted according to the "Show message security" icon. If I send a normal message to an account that has no known encryption setup, then the message arrives and the "Show message security" button is missing (correctly).

Any ideas why this is happening? Thanks for your help.

I use FF 116 on windows 11. For months, I have had problems logging in to web sites. At first I thought the problem was with the web site, but I have come to the conclusion it is an FF problem. GlobeandMail.com, gem.cbc.ca and rbc.com for example ask for me to log in. I go through the steps giving my password and login name and the web site seems to accept these without complaint but it continues to want me to log in. I end up having to use Edge which works fine. Is there a solution?

Not so newbee here. Very long career in S/W, but 20 years as a Luddite so now trying to catch up.

3 gmail accs - all good. 3 hotkey accs - receive ok, but cannot send - broken recently. These old legacy accs were taken over by iPrimus but are still visible/SameSameBroken at hotkey webmail.

1 of the 3 hotkey is set to Default. It is MORE broken than the other 2. How do I remove this Default? I will choose a gmail account to be the Default. But how exactly do i unDefault the hotkey acc.

No, I don't need nor want, to use iPrimus pop/smtp settings. Yes, the broken hotkey smtp issue is probably no biggy - just work in hand.

Thanks for any assistance... I see this thread is very busy. ps, I remain committed to the goals of Open (free) Software. If only the worldview was as committed, how good it would be for everyone!

In TB 115.1.0 (64-bit) on Windows digital signature are maked as not valid for an unknown reason. This happens at least with emails send from Outlook clients. In TB 102.14.0 (64-bit) on Windows this digital signatures were shown as valid. However, digitsal signatures of emails send from other clients (e.g. Thunderbird, Nine from 9folders) are shown as valid.

Hi there! I am a long time Chrome user and decided to try Mozilla Firefox. I loved it and after a bit of tweaking, I run into a problem I can't deal with myself. In Chrome I loved auto fill options every time I needed the option for my home address, email address or credit card. In Firefox I just can't do it. The option is only available for Canada or SUA. Is there any way I can make it work? Of course, I looked for some add-ons and actually found several, but given the fact that auto-fill in my case deals with personal and sensitive data, I need a safer method. Is there any? Thank you!

Hi, 3 weeks ago I suddenly could not log in to my email without errors.

First I get a Google screen "Choose an account" showing the three Gmail accounts I use. I select the first one.

"Mozilla Thunderbird wants to access your Google Account". This refers to calendars. I take the Allow option.

Then I get the message "Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to localhost. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

When I close this window I get another Google screen .

"Mozilla Thunderbird wants to access your Google Account". This refers to i) mail, ii) contacts, and iii) calendars. I take the Allow option.

Then I get the same message message "Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to localhost. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

This process cycles through the other two emails. Then I get and authentication failure message.

I have seen hints that this might be a certificate issue but I have tried in vain to find certificates stored in Thunderbird.

Any help approeciated.

Thanks
