I used to be able to send emails using Thunderbird to Office365 using SMTP, but it is no longer working, although I'm still receiving emails.

Getting the following error: Login to server smtp.office365.com with username ***@*** failed

Settings Server: smtp.office365.com Port: 587 Encryption: STARTTLS

The problem occurs with Windows and also Mac OS (I installed Thunderbird to help troubleshoot).

I'm using Office 365 Family, so there is no option to manage the users, as there is in the business version, and which has been suggested by others with the same problem.

It's unclear to me if the problem lies with Thunderbird or Microsoft (I suspect the latter). Any advice would be very welcome.

Greetings from North-East of France, since a few weeks ago I'm seeing a (sort of) pop-up window suggesting to login with a Google account (see the screenshot attached). I've done some internet search to find out how to get rid of it, but the only suggestion I get is to modify an option in a Google account. However, I do not have a Google account! How to get rid of this disturbing pop-up? I already use Adblock Plus and uBlock Origin, yet Google passes through them! Thank you in advance for any help you may provide.

There's a web site I use very frequently that I suddenly cannot access any longer. I got the error message, "404 Bad Request," followed by "Request Header Or Cookie Too Large," and then "openresty/1.15.8.2." This only appears with Firefox. Microsoft Edge loads the sight just fine. What's going on here?

I have just received this message from Google / Gmail:

"Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0"

I currently use an older version of MS Outlook that apparently won't work after these changes are introduced.

My question is - will Thunderbird work with Gmail after the 30th May deadline? Is it compatible with 'Sign in with Google'?

Thank you for your help.

When I surf Youtube, Google, Facebook and anything on Firefox this following error happen every time. Please help me.


Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection.

What can you do about it?

www.youtube.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

How to make Thunderbird 91 work with Yubikey 5? Works with 32-bit Thunderbird, but not 64-bit.

Hello, I received a Yubikey 5 and all is working fine using GPG with it, except integration with Thunderbird on Windows.

I followed this guide: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards including 64 windows section

I was able to successfully send mail to myself, but then thunderbird failed at decrypting this message: Thunderbird is indicating that key is not available and I see no prompt from gpg-agent. Key is correctly declared as GPG external.

If I try to decrypt tis email by storing it on file and using gpg in command line, it works fine: agent is asking for Yubikey PIN and gpg is decrypting the message. But this is an awful workaround, not user friendly at all.

I also did sanity check by sending to myself a message encrypted with a key generated by Thunderbird: all is working fine, the message is decrypted within Thunderbird.

=> How do you make Thunderbird decrypt message encrypted with key stored in Yubikey? How do you make the gpg-agent called by thunderbird?

Running v104.0.2. (UK) Whenever I have an 'email box', I get an autofill email address appearing I wish to delete. When I highlight the address, and hit 'delete' it doesn't work. On searching a method, I get the suggestion to go into settings and drill down in the 'Forms & Autofill' section in 'privacy' settings, but my FireFox has no such section.

I then tried to 'activate' the section by going into 'about:config' and changing 'extensions.formautofill.available' from, 'detect', to 'on', it made no difference, I still have no 'Forms & Autofill' section in settings.

How can something so simple be so complicated?

I am trying to get S/MIME set up properly. I have my personal certificate set up and installed - I can send signed messages. However, when I try to send an ecrypted message to a recipent with a DOD certificate, I run into an error that the certificate is not valid. I have installed the DOD root certificates, trusted them for email/websites, and imported the individual's signature cert into the store.

How do I change the settings / trust on the individual's certificate to trust it? It is within the valid date range.

Hello I'm referencing the topic where TLS 1.0 and 1.1 support was removed but rolled back to accommodate some government agencies / sites and support for COVID-19 data

https://support.mozilla.org/en-US/questions/1290040#:~:text=Mozilla%20and%20other%20browser%20makers,and%20performance%20of%20Internet%20connections.

Quoted answer "Right, support for TLS 1.0 and TLS 1.1 has been removed few months ago, but we reverted the change for an undetermined amount of time to better enable access to critical government sites sharing COVID19 information."

Since it was referenced as "undermined amount of time", is there anything currently on your roadmap/release schedule in regards to removing support again? I have some cutover decisions I need to make and knowing if ESR for example will remove this support in 2 months may effect the direction of those. If you have anything to share, i'd really appreciate it.

Regards,

I recently changed Firefox settings to delete cookies for everything when I close it except the sites I use frequently. This has worked great for everything except for Google sites which sign me out every time I close the browser.

I assume there are some supporting sites for signing in to Google that need to be in the exception list, but I don't know what they might be. I'm also using Mozilla's new Multi-account Container extension in case that matters.

Thanks for taking the time to read this.

When I enter my SMS code as part of SSL/TLS security OAuth2 authentication method (see my account5 below) I get the following: __________________________________________________ Need admin approval Thunderbird www.thunderbird.net

Thunderbird needs permission to access resources in your organisation that only an admin can grant. Please ask an admin to grant permission to this app before you can use it. Have an admin account? Sign in with that account Return to the application without granting consent __________________________________________________

I don't know what app is being refered to in the above message but I am the administrator of my account and have given full permissions for Thunderbird to cross Windows Firewall etc. etc.

Since this problem started this morning I get the busy rotating symbol when accessing my account5 mail directories and their contents do not appear to be updating.

First of this issue is atleast 4 years old. I found various different people having this problem. https://bugzilla.mozilla.org/show_bug.cgi?id=1432644 It should be a P5 not a P3. This official Mozilla article: https://support.mozilla.org/en-US/kb/add-trusted-websites-your-allow-list-firefox-focus Does NOT work.

I am trying to add an expection to tracking protection but there is no such option, as descriped at Bugzilla. In the adress bar i removed the tracking protection for a website. But it was NOT added to the exception list. I dont allow 3rd party cookies and auto delete cookies when closing Fox. I think that is the reason why it's not working, if this is the case it's a bug.

What i actually tried to do, using dark-theme from duckduckgo permanently. Because as right now, i must change the theme every single time i reopen Firefox. This is Bull**** honestly. Even when i add duckduckgo as an addon, it does not save the dark theme!
