""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.

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

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?

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

On every new release of an update for Firefox, the update process deletes all of my saved cookies that I have established an exception for. I do this so that I don't have to continually enter my user name and password for sites that I visit regularly. The developers must change the updates so that the exceptions carryover to the new version of Firefox.

Hello All,

I have recently installed Thunderbird email client which populated on its own and before I was asked for an address or Password! This may be by design which is not an issue as such. However, I noticed that none of my Laptop, WIN 10, Windows Live Mail subfolders were present.

I had imaged at some point I would have to import all my Folders and the emails from Window Live Mail using the importexporttools-3.3.2 program. I have also been made aware that sometimes the process would not be without errors. Nevertheless I forged ahead.

Unfortunately I have discovered there are odd emails missing. It seems I have two options to try and recover the missing contents. 1) To delete Thunderbird client altogether and fresh install, plus to import folders and emails again. Or 2) To repeat the import procedure by over writing, which will hopefully add the missing emails!

However, I have two questions, if I am able to over write. 1) Is it possible to repeat the import again? 2) Will the result be I end up with hundreds of duplicate emails as well as those missing emails?

Perhaps someone has experience of the outcome.

Thank you in advance.

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

I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.

Recently a popup notification came up when I opened firefox on my mac. Its been awhile since I opened it and without thinking I clicked : o ~ Now I worry if it'ss ledgit? Does Firefox give a popup box in top right corner when it needs an update? I wasn't on any strange website or anything but I'm always concerned and dont remember seeing that before.

My firefox now says its up to date after it restarted ~ it's running 125.0.3

Any advise is appreciated.

I have two Zebra TC8000 hand scanners running Android OS 5.1.1 that I've reset to factory defaults. I need to download and install Firefox but each installation attempt fails either at the download or at installation. No real detail is given as to what the issue is. I just get a message "Queueing" or "X App not installed."

I've attempted to install our regular APK that has historically worked fine. The download location is... https://download.moziilla.org/?product=fennec-latest&os=android&lang=multi The APK from this site no long downloads. The download status just shows "QUEUEING" for 5-7 minutes then fails.

I switched to browsing directly to the Mozilla FTP page and attempted to download several versions of Firefox for Android. The latest version 125.0 at... https://ftp.mozilla.org/pub/fenix/releases/125.0/android/ Here, I tried installing each of the three APKs offered here and receive the message "X App not installed" with each attempt. I am, at least, able to successfully download the APK and launch the install but I can't get the install to work.

Any clue on what could be wrong?

According to Help>About Thubderbird the current version is 115. But searches in my browser tells me the latest version is 105.

Am I not searching deep enough?

Thanks, James

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

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.

Since installing Ubuntu 23.10 on my new desktop pc, Thunderbird is failing to see the account details in .thunderbird I copied all the files from my backup into a new account directory (/home/cfi/.thunderbird/y4xyxmli.default), a technique that has worked many times in the past, but not this time. Previously, thunderbird has simply taken the settings from the backed up files and used those to connect to my organisation's mail server. Any ideas? How can I force Thunderbird to read the old account settings?

Many thanks.

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?
