My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

Hello,

Trying every conceivable method to move my Thunderbird data to a new computer, following instructions exactly.

First I copy all the contents of the Thunderbird directory from %APPDATA%\Thunderbird\Profiles\ on the source computer to a USB drive. Next I copy that folder to the same location on the destination machine. I am copying the Thunderbird directory and all subdirectories. Run Thunderbird, no mails, nothing.

Thank you

When in Thunderbird trying to import old profile from backup media using the import tool, I get an error message saying "about:preferences : unable to run script because scripts are blocked internally" How do I manage this? Can´t find anything about it on help pages. / Olle

Thunderbird stopped sending and receiving emails. I installed a new copy of thunderbird on another computer. After some time I was able to get it functional there. I would now like to have the same mail folder structure on the new machine as the old and import all my old information. I have exported the contents of the old Thunderbird profile to a usb drive. There are a large number of files and folder - 167 to be exact. The path the to the profile folder on my old computer was ....AppData\Roaming\Thunderbird\Profiles\t3ozjfx.default. This is the 'Local directory' in the Server Settings on the old computer. The path to Profile folder on the new installation is also ...AppData\Roaming\Thunderbird\Profiles\ but then there are two profile type files. One called t3ozjfx.default as before and another called test.default. The 'Local directory' in the Server Settings on the new computer is .....AppData\Roaming\Thunderbird\Profiles\t3ozjfjx.default\ImapMail\mail.cts.com-1.au It took me a great deal of effort to get emails sending and receiving properly on the new machine. It should have been just a matter of having the correct port addresses, server name, and encription method. However one had to fiddle with the local directory path to get operational

My question is given the above should I be able to get my old email file structure and the contents of those files onto the new computer by using the import facility in thunderbird. I would also like have the 'sent' messages on the old computer on the new computer. Will the thunderbird import operation be able to do this using the profile file information I put on the usb memory.

I hope I have not been too tedious in asking this question. It would be an immense relief if I could get Thunderbird on my new computer to have all the contents and folder structure that I had on the old computer.

sincerely yours

I posted the following question 1 month ago. Can anyone help me with this, it's driving me crazy! Please respond.

- Open TB - Open Inbox to see all emails - Open an email, read it, delete it - Scroll down, reading email Subjects until I find another email I want to open (this may be 30-40 lines or more) - Open another email, read it, delete it

The cursor/highlight then jumps back up to the previously highlighted email (next to the first email I deleted). Now I don't know where I am, I don't know what email Subjects I have already looked at, I don't know where the next unlooked-at email is. In order to get back to where I was before I deleted the second email, I have to scroll down through many emails I have already scrolled through.

How do I stop TB from doing this? I want the cursor/highlight to stay right where it was before I delete any email, I do not want it jumping to some previous location.

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

What is the minimum version of Ubuntu to install Thunderbird 115 supernova? I'm on 20.04 on ZorinOS.

And by the way, when are you planning to make it available on APT?

Thanks, Tal Sabadia

Since about two months ago, I haven't been able to update Firefox(or any other browser for that matter). I've tried the typical method of going to Preferences, checking for updates, but I can't get passed that point. I get this error message stating "Failed to check for updates."

Chrome was giving me much of the same issue, I've allowed GoogleUpdate on my firewall rules, restarted the PC and tried again. Still got the same error message. I have no other antivirus software installed on this device other than the Windows Defender default app. Firefox hasn't told what I should be allowing past my firewall so I haven't tried anything similar for Firefox.

I also tried uninstalling Firefox, but when I tried to reinstall, I couldn't finish that process because clicking on Download Now led me to this error message stating "Hmm. We’re having trouble finding that site.

We can’t connect to the server at download.mozilla.org."

I assumed this was maybe a DNS issue. I tried a DNS flush but that also was ineffective. I tried changing my DNS servers to 1.1.1.1 and 1.1.1.2, also tried other known DNS servers but that didn't work either.

In the meantime, I'd like to at least get an offline installer going because my current version is 110.0.1.

Thank you.

I set up thunderbird email account on my computer and my iphone. I can only send and not receive emails on my computer account and I can only receive and not send from my phone account. When I try to send emails from my phone the email bounces to my outbox where it sits and I get a message that says "Cannot Send Mail The sender address was invalid" I think something was off in the initial setup because this problem has persisted from the beginning however I cannot figure out how to fix it. Need help please so that email sends and receives from either location: computer or iphone.

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

I have two questions.

1) I have several email accounts, on various domains with various hosts, that I want to access with Thunderbird. I've installed the first one okay. But when I go to add another - Tools / Account Settings / Account Actions / Add Mail Account - it goes to a tab "Account Setup" showing the settings for the first account. I don't want to overwrite those settings, replacing the first account with the second. I want to add an account, not change the account. How do I do that?

(If I'm just supposed to change the settings that are already filled in for the first account, the interface is extremely confusing. For that matter, the expression "existing email address" is confusing - at first I thought it meant an address already added to Thunderbird, rather than an address hosted elsewhere - these things should be changed.)

2) In some cases I have multiple addresses at the same domain, and I'm using Windows 10. The following exchange is from 7 and 5 months ago. Has the issue been resolved?

I am using two different email accounts on two computers. I have a new computer that I want to migrate both account on to. I was successful in moving one of the email accounts on to the new computer using your on-line instructions. I'm having an issue with the second account. I created another email account and was able to create the second email account on my new computer but when I did the old saved files/emails did not move over.

How do I move the second email account, with all of the saved emails/files/folders to my new computer without damaging or losing the first email account? thanks

Yesterday you people helped me get layout.css.devPixelsPerPx to the right value. In reading other posts, and in an effort to make text larger (I'm visually impaired), I tried a value of 1.125. Now I see only a tiny black box where TB should be. I know it was stupid, But I desperately need your help. How can I find the config file and edit it with a text editor so the value is again -1.0. And I promise to not cause you generous people any more problems!!!!

As of the newest TB version out July 31, 2023, I cannot send outgoing emails. Never had this problem with TB. After years of happily using TB and loving its wonderful functions and features, this inability to send outgoing emails is a mystery. Tried just about everything, but can find no fix. Tried to find a Mozilla-authorized earlier version to replace the newest version but could not find one on a Mozilla-authorized site to download.

Worked with 7 computer techs from the company from which I bought my new Win 11 computer this year--they couldn't find a fix. Worked with 5 techs from my Internet provider but not one of them could fix the outgoing email problem. Uninstalled, re-installed, repeated, checked all settings, stopped security software--nothing fixes the problem. My Spectrum webmail still brings in my incoming and sends out my outgoing emails but TB does not send the outgoing. I can only conclude the problem is the newest version of TB. Am I right? Is a fix on the way?

Who has run into this problem and how have you fixed it? Already spent 2 1/2 days working on this and not even the "computer experts" have a clue. Any TB heroes out there who can come to the rescue? Or should I wait a few weeks until this glitch in the newest version is fixed? Thanks in advance. I'm lost without my wonderful TB!

On android playstore, I am getting a message that a firefox update is available. But there is no description about the update. How to find out authenticity of an android app firefox update and its version and reason for the release.

I have a Win 10 PC (64 bit) that I've given to my wife. I tried deleting my Thunderbird software from that PC and downloaded and installed a new instance of Thunderbird for my wife. I used the import tool to bring her profile from her old Win 10 (64 bit) PC to the new (for her) PC I've given her. That import seems to succeed, but upon restarting Thunderbird, all my e-mails, etc. appear instead of hers. How can I do this?

Thanks for any input.

I do not like Thunderbird version 115, and I want to migrate back to version 102.15.0, where can I get a download of 102.15.0 - or is there an automatic removal to go back to the previous version

The hard drive on my PC running Windows 10 crashed and I have a new one running Windows 11. I used Thunderbird on the old PC and am trying to set up Thunderbird on the new PC. My email account is with AOL. When setting up Thunderbird on the new PC, it asks for the password. I am trying to use the AOL password but it does not work. The same password works on other devices. I have no access to the data on the old hard drive. Any suggestions greatly appreciated.
