Can I use thunderbird with multiple accounts on multiple PC's and stay synchronised?

I have two PC's i want to set up - it seems like i have to create a new account for a second PC rather than pick up the account set up from the first PC.

Hi. From 27 feb I can't login to yahoo mail through mozilla thunderbird.

When I start thunderbird, new windows is opened with this link

https://login.yahoo.com/account/challenge/fail?src=oauth&client_id=dj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz&redirect_uri=https%3A%2F%2F127.0.0.1&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz%26code_challenge%3Dt6iqw87GVPZ649cCvOEh2L1hwkUluBhsrwxCdVTXAOY%26code_challenge_method%3DS256%26redirect_uri%3Dhttps%253A%252F%252F127.0.0.1%26response_type%3Dcode%26scope%3Dmail-w%2520ycal-w%2520sdct-w&acrumb=0EYriz7Z&display=login&authMechanism=primary&e=true&pcn=password&eid=3692

When I tried to login I see this information:

An error occurred.

We couldn't log you in. Please try again from a different device.

This is very strange, because I tried it on another PC and this is the same. It looks that yahoo even didn't try to check password, because this is not matter if I wrote correct password or different - I see the same information.

Please help. I have two yahoo mail account and this is the same.

Both accounts works well on another e-mail client and I can access to my account without any problem by browser. This is only thunderbird problem.

Just started using Thunderbird, coming from MS Outlook. I have exported my contact details in Outlook to a .csv file, and tried to use this as the import source to transfer the details to Thunderbird address book. I have checked the fields to transfer, but none end up being passed over. The .csv file appears to hold the correct data with the correct field headers. Although I do not have many contacts, transferring them individually by hand seems a very old-fashioned thing to have to do lol

I can't access one of my Gmail accounts. I have tried everything I can think of for the past 2 weeks. All because I have lost my device and also had to change my phone number and email addresses. I noticed today that the recovery email is a Firefox Relay emails. Is it possible to redirected to my new email address?

I have an answer to a sent email to my firefox "relay" address and cannot find a way to retrieve it from that "relay" email. How do I access that generated email site?

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript

If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

Firefox crashes whenever it would need access to my camera or microphone. So far it has only happened whn trying to access a Roll20 game with camera and microphone connectivity, and when trying to access a video appointment for Universal Credit. It never happened on Windows 10, but since updating to Windows 11 it happens every time without fail, and the crash is immediate.

Hello people,

When I compose a message in my word programme (Softmaker or Libre), save it in Docx format and copy/paste it into Thunderbird to send it everything is double spaced and nothing I do in the "compose" menu can change that.

I have tried it with "Use Paragraph Format" checked and unchecked and it stays doule spaced and nothing I can find in previous threads seems to address this problem.

What am I missing?

As stated above, received msg from me to me -- a common practice I hear. If I change my password, will that fix this? I tried to log in to Outlook on line to change password but I use a passkey - doesn't let me do a password entry. Help..... Thanks.

All of a sudden, my default search engine changed to Google. I didn't do it and don't want it. The "settings" still show Firefox as my default, but it doesn't stop Google from hijacking my searches. I want to get rid of it.

I don't know what to do when February 29 is in my calendar, 2026 is not a leap year. I've found nothing to help me. I have the latest version if Thunderbird. Thanks

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

good day....ii hope someone can help. the other day i was accessing my yahoo account spam folder and by accident, i deleted the spam folder instead of emptying it. the spam folder is now sitting in the trash and i'm unable to remove it from there. when i log into my actual yahoo account, the spam folder is where it's supposed to be and not in the trash. i tried removing the yahoo account from thunderbird and reinstalling it in hopes that it would rectify the problem, but it hasn't. does anyone have a solution?? i would greatly appreciate any help you can offer. thank you for your time...mike s

Hi, T/bird working fine upto Thurs night Feb 26th then yesterday morning I got pop up windows asking for login credentials. Nothing had changed. Tried logging in thru them put it errored: <<

               Something went wrong

We could not sign you in. Try again from a different device. >>

I can log into my Yahoo accounts using Firefox so passwords isn't the issue

I've read thru a number of threads on here and elsewhere but no solution so far. K9 is working on my Android phone and my wife's and her T/bird is working on her PC. Just checked versions, she is on 140.8 ESR and I'm on 148.0. Both running Win 11 Pro.

Tried changing from OAuth2 to Normal, pop window asking for password but that doesn't work

Seems to me to be an issue with Ver 148.0 as my wife's working

What am I missing?

I have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated

I have smtp.gmail.com set up as my outgoing server (port 465, username = my gmail address, Authentication = OAuth2, connection security = SSL/TLS, also tried STARTTLS with port 587). There doesn't appear to be any way to set the password in the "Outgoing Server (SMTP) Settings", even when I click "Edit". Nor can I add a password to the "Edit/Privacy&Security/Saved Passwords" dialog box (which allows you to see existing passwords or remove them, but not add any).

When I try to send an email, the "Sending Message" dialog box pops up, and after a few seconds a second box pops labeled "Login to account 'smtp.gmai.com' failed". This box has three buttons: "Enter New Password", Cancel and Retry. Clicking on the "Enter New Password" button does not offer me the chance to enter a new password--instead, it immediately takes me back to the "Sending Message" box, which then immediately takes me back to the "Login...failed" box. There is never an opportunity to enter the password!

TBird 140.7.0esr, Thunderbird for Linux Mint. Mint version 22.3.

Sending works ok if I choose a different SMTP server.

During recent update 148.0 (64-bit) google calendars are not shown either in "Events and Tasks/Calendar" or in "Today's Pane".

Subscribed calendars are still there, but nothing is shown in the days/weeks/months entries apart from the first calendar in the subscription list! Nothing else. And nothing in today's pane.

Reinstalled Thunderbird and reinstalled "Provider for google calendar" but nothing changed.

Thanks, GG

Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁️), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I am using Firefox version 147.0.4 (aarch64) on a Macbook Air running macOS Sequoia 15.5.
