For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

Been using Outlook, but am having issues. Decided to try TBird. Got the email part set up (far as I can tell). Calendar and Address book are a different story. Calendar: Using Google Calendar as primary calendar. Consists of an appointment, birthday, and holiday calendars. Created a new calendar and entered the URL for my Google Calendar. It showed up in TBird apparently OK. Created ANOTHER calendar and entered URL for Googles stock Holiday calendar. It also seemed to show up OK. Tried to do what I did with those calendars to add my Birthday Calendar, but Google uses data from Google Contacts to create that calendar. Can't figure how to add that data. HELP? Address book: Exported Google Contacts Data to a CSV file. Tried BOTH Outlook CSV and Google CSV exports. NEITHER produced a CSV file ANYWHERE Close to what TBird appeared to want, based on what showed up on the "fields" page that appeared after I chose the CSV filename. Moving data around in a spreadsheet is a Royal pain. Isn't there a Google Contacts CSV export file that more closely approximates the arrangement that TBird WANTS?

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

As of today Cox is moving all email services to Yahoo. I have been using Thunderbird for Cox.net email. I have about 40 existing folders under cox.net. Yahoo now has Cox.net and is providing my new emails so I still have the same email address and can access it through webmail. What is the best way to transition this from the old Cox cox.net to the new Yahoo cox.net on Thunderbird and keep all existing folders? Thank You

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

Dear Mozilla:

It is SAD that the OS I have will no longer be supported due to exploits.

Considering the # of exploits, backdoors, poor coding, etc., in the later Windows OS versions - 1 would truly think that supporting the older and MUCH more secure Windows OS's would be wise.

Yes, they have "holes", but overall much fewer than current OS's.

Plus, the bad actors are very busy exploiting 10 & 11 and pretty much have ignored the prior versions.

Question... what if a major exploit is found that affects all OS's from 11 down to unsupported?

Will Mozilla make sure to supply a patch to the unsupported due to the danger of the new & serious "hole" found?

I vote... it would be wise to maintain a small contingency of legacy developers to help those who cannot buy new systems or flat out HATE the UI & UX of the 10 & 11.

Makes sense?

Hi there,

I had 755 emails in a label in one of my two gmail accounts. I linked by gmail accounts in thunderbird and selected 'copy' of the label from one account to the other. However, only 359 have transferred. I've tried again and nothing has changed. Its made a big mess of both my gmail accounts.

As I move from an old computer to a new computer, I can't seem to remember my old computer's T-bird password, which asks for the new computer download setup. Where can I find the password on my old computer?

Hello,

I was using the previous version of Thunderbird (115.10.0) (64-bit), which was crashing upon exit. I tried to update by clicking on Help and About Thunderbird, but it didn't automatically update to the newer version (115.10.1 (64-bit)). So the instructions I followed was do download the new version. However, when I open the new version, all my email accounts and calendars are missing. How do I restore my old profile?

Firefox keeps reminding me that updates are available. I download and it says its installing but it doesn't seem to update. I have tried closing Firefox before running the installation but it makes no difference. I am on 125.02 at the moment.

Hi there. I love Firefox, but I have an issue at the moment where I have one copy set up on my Mac, and it has two profiles. However, I'm running into regular problems where they're both open and they can't quit, or they crash, or they want updates, the other one, and then it has to be restarted and can't open web pages for stuff like that.

A little bit more about my setup. I have two admin accounts on my Mac and an applications folder with Firefox in it. Then each of my Mac accounts has a version of Firefox with a different profile.

I'm about to do a clean install of macOS with the two admin accounts. I want to install Firefox correctly this time. How do I have two entirely separate copies of Firefox running on my Mac in the two admin accounts? I just don't want their threads to be mixed or them to be updating each other or anything like that.

Absolutely love Firefox, but this has been quite a big issue for me and I'd love some advice here. Thank you.

Additional note, I followed the link below the first time I setup to create two profiles, but that didn't quite do what I wanted.

I have the latest version of Windows 11 installed. When I try to download Firefox 125 I get a popup window stating Firefox 125 cannot be downloaded on a computer with the operating system less than Windows 10. Is there a work around to remedy this problem?

If I try to import Mail Message in Outlook 2016, the progress will not proceed at 0%

Both Outlook and Thunderbird were running on 64bit

How to solve this?

Cox Communications recently discontinued its e-mail services but provided a simple, direct transfer path to Yahoo Mail. The transfer retained the '@cox.net' referent in the e-mail address -- e.g., 'myusername@cox.net' -- to make the transition to Yahoo Mail seamless for all correspondence. The new Yahoo Mail username also now includes the '@cox.net' referent -- e.g., the former 'myusername' under Cox is now 'myusername@cox.net' under Yahoo. The transfer was successful, and e-mail send & receive functions for all of my old Cox accounts now work on the Yahoo Mail servers -- but ONLY in Yahoo's webmail.

in order to get Thunderbird to recognize my existing accounts under the new Yahoo regime, I went to 'Set Up Another Account > Email' and entered the required information, as illustrated in the attached screenshots. (See attachments 01 & 02.) The Set Up procedure initially found the old Cox server settings, apparently from Mozilla's archived data for the account. I Then performed a manual configuration, and, as indicated in the attached screenshots, the Set Up procedure also successfully found the new Yahoo Mail servers. Success, right?

Wrong! When I restarted Thunderbird, the new Yahoo Mail server settings were in place, but the username had not been updated -- it lacked the '@cox.net' suffix. After manually amending the username and again restarting, the new server settings and amended username were in place, but connection to the Yahoo servers failed repeatedly. (See attachment 03.) A second round of the 'Set Up Another Account > Email' procedure revealed that the archival Mozilla data had not been updated -- it still pointed to the old cox.net settings -- and a second manual configuration led to the same results as the first: Thunderbird failed to connect to my account on the Yahoo Mail servers.

I then looked for a way to completely remove the existing account from Thunderbird, and then to create a new account from scratch for the existing account on Yahoo Mail. I consulted Thunderbird online support advice [ref. 'Close My Account - https://support.mozilla.org/en-US/questions/1395523 ]:

"If you created a mail account in Thunderbird for a particular email address to download emails from server then you can easily remove it ( Menu icon > Account Settings -- Select name of account in Left Pane -- Click on 'Account Actions' -- Select :'Remove Account'. -- Restart Thunderbird. ),"

However, I could find no 'Remove Account' selection anywhere in the version of Thunderbird that I am using (ver. 115.9.0 - 64-bit)!

Please explain what I must do:

   1. to make an existing Thunderbird account originally set up for an old '@cox.net' address hosted on Cox servers now connect to a new '@cox.net' address hosted on Yahoo Mail servers; 

or, alternatively,

   2. to remove all traces of an existing Thunderbird account originally set up for an old '@cox.net' address once hosted on Cox servers, and then to set up a new Thunderbird account for the same '@cox.net' address now hosted on Yahoo Mail servers.
