TB 91.7.0 (64-bit I used to send/rcv gmail no problm, started having issues ~ Oct 2021 I then setup a 3rd party app password in gmail account for thunderbird. That allowed me to Send Gmails, but, not receive it kept asking for password. Then I read to use OAuth2 and saw that Google will no longer allow 3rd party app passwords, so i deleted it in google, and set both Imap.gmail.com and smpt.gmail.com to use OAuth2 (both set for SSL/TSL). I did this just for smpt first when the 3rd party app password was still enabled, i could recv but, when i went to send, it would ask for password, i enter it, then it would sent msg to my cell phone to Allow thunderbird, i would press Allow on my phone, and Thunderbird would come up with Sending message.. with the progress marked all way to end BUT, it will never complete sending.... I have to hit cancel it then shows Failed message unable to authenticate. After I deleted the 3rd party app password in gmail settings, now when i start thunderbird or try to receive emails, it goes through the same authorization process with my phone, but, then never downloads any new emails. I have spend HOURS on this.. extremely frustrated (I have been forced to us ms mail which i really don't like, i am too used to thunderbird (although I wished thunderbird had check boxes on emails to select via checkboxes for delete, or moving, etc)

I would like create a back up of my local folders (26 years of emails) in the cloud. Reading questions posted here, the recommendation is to backup the complete 'Profiles' folder. However, when I try and do so, I am not successful because at some point the backup process glitches out. (I am trying to upload the folder to a Microsoft OneDrive folder and have tried on both my PC running Windows 7 Pro and a Macbook running OS Monterey.) I suspect that my internet connection is not stable enough to copy 30 GB (about the size of the 'Profiles' folder). Is there any alternative to backing up the complete 'Profiles' folder?

I am getting the Mozilla Thunderbird Email wants to access your Google Account all the time while using TBM, I have removed the gmail account and the pop up does not show, so I know it is for the email account just removed. I re-add the email address and enter the email address and password and let it find the config itself. Click Done, and get the Mozilla Thunderbird Email wants to access your Google Account again, then click Allow and get the Authentication failure while connecting to server imap.gmail.com. message in the bottom left of my desktop. How can i get gmail to work again please.

Hello, While the display size is correct on my MacBook Pro 2021 screen is OK, it is huge and unusable on my second monitor (see images). My layout.css.devPixelsPerPx is set at 2.5. If I set it at default (-1), the external monitor display is OK, but the internal monitor is so small that it is unreadable (to the extend that it was actually hard to figure out how to revert back to so I moved the window to the external monitor). This is a bug. There should be a setting per monitor or the default should follow the System Preferences setting for all monitors.

Please fix this quickly!

Thank you, Alain Damlamian p.s.: I tried to upload two pdf images but they were refused (why only accept jpg ?)

I have been using Thunderbird for many years and have previously updated without problem. But upon updating to version 102.1.2 I suddenly couldn't see my folders or emails (see attached image). However, if I search for an email I will get a list containing the relevant emails, but as soon as I click on an email in the list I go back to the blank screen like at login with no folders or emails.

I have trawled through related fixes and have tried deleting all of the .msf files in my profiles but to no avail. I really hope that someone will be able to assist.

Lately I'm having trouble with my connection with outlook. I use a free outlook email address. Sometimes (not always) when starting Thunderbird, I get the "user authenticated but not connected" warning. After a while it's working again.

I have tried several settings but can't figure out what solves this issue.

I'm using port 993 / SSL/TLS and authentication method is set to normal password.

Most of the times this works.

When I switch to OAuth2, I get the Microsoft screen to login to my work / school account which I do not have.

I've search the web to find a solution for this but I can't find it. Hopefully someone can help me out because it drives me "nuts" ;)

I would like to see the sender's email address in lieu of a name.

The inbox SELECT COLUMNS TO DISPLAY does not offer an option to DISPLAY THE SENDER’S EMAIL ADDRESS.

Both From and Correspondents display the same names. Perhaps replacing one of those with the SENDER’S EMAIL ADDRESS?

Please see the attached. On the upper part of the email, the font is extremely small. I've tried everything I could find to make the font larger, but haven't found the solution. On the bottom part, the font is larger. That font I can adjust. Can someone tell me how to enlarge the font on the upper part of the emails?

I hope someone can help me. Up until the last week or so, I have had no problem with my signature file in outgoing email. I've been using the same signature file for at least 5 years. Suddenly, Thunderbird is blocking my logo image in my signature file in all outgoing mail. Instead, it is showing my alternate text. I am using version 102.6.1 on Windows 10

Answers to the question "how to turn off all threading in Thunderbird" no longer work with changed menu structures in Thunderbird 115. What is the answer to this question now?

I have installed Thunderbird and logged in via Google account and I have no problems with receiving e-mails, unfortunately sending out does not work. Somebody told me to choose OAuth2 but this option does not exist for the "sending out" server. My email is on gmail. What to do? Witoldrem

To increase the font size of TB I know I can click View, Font Size, Increase Font Size . But I need to know how to increase the font size of a received email. Its too small.

About 10 days I started getting nthe following error message.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Too many failed authentication attempts.

I have a gmail account and this works fine, my incomming POP account is OK, but the outgoing mail mostly will not send. The error corrects itself occasionally and works OK. I have checked all the settings and raised 2 calls to LCN who assured me the error was not at their side (my webmail still works OK). Any suggestions, I have deleted the password and re-entered it. Many thanks .

I have had the same issues with TB freezing and locking up my PC that many here have had. For me, this has now gone on for almost 3 years. I have done everything I can think of, and everything I have read about online to deal with the constant freezing. I have: --upgraded countless times (now on Ver 102.9.0, 64 bit, Win 10, 32GB RAM, 3TB hard drive) --reinstalled Thunderbird many times --deleted various profiles and created new ones, deleted various config files as suggested. --reinstalled Windows 10, upgraded all associated files, drivers, etc. --started Windows in Safe Mode --disabled all add-ons and extensions in TB --reset all toolbars and controls in TB --started Thunderbird in Troubleshoot Mode --gave an exception to TB in my Windows Defender [and turned off Defender entirely] --ran MANY virus scans --disabled ALL virus software

Thunderbird is the ONLY piece of software on this PC that locks it up. It exhibits the same behavior that many here are seeing: freezes when I try to click on something; freezes when I try to reply to an email; freezes for no apparent reason. I can't MAKE it freeze up... it just seems to do it at random, constantly. Right now, it's open on another screen and has been frozen for about 3 minutes, and just unfroze. Most of the time, it freezes so that I cannot shut TB down. It is completely unresponsive. Sometimes it will freeze the computer so that I cannot do ANYTHING... I cannot open Task Manager and force a shutdown. Eventually, it releases and works again, only to freeze up a few minutes later.

I'm pretty much out of ideas, but I continue to browse online, looking for answers. As I said, three years of this is enough, and I see complaints about this going back even further. I love Thunderbird. I'm a longtime user and have not found any email client that comes close to the way TB works for me, so I'm VERY reluctant to leave. But I'm really tired of being a beta tester. And yes, I have donated many times over the years, and I'm happy to do so. I'm not concerned with the money. I just want it to work like it used to. If you have any fresh ideas, I'm very open to hearing them. But a warning, that I have likely already tried the fixes offered. I appreciate any input, in any event.

So, unless a miracle comes along, I reckon I'll have to cut bait and find a replacement for Thunderbird. Thanks for allowing me to blow off some long-held frustration.

best,

I had problems with thunderbird email text too small. Resolved that but now the title line with subject to and from is too large. How do I change it. Windows 11 latest version of thunderbird.

The inbox had about 18 months worth of emails. I deleted three emails that had been flagged by Thunderbird as spam. Then I went to the trash folder and permanently deleted the trash that included many other unwanted emails.

When I returned to the inbox, the full list of emails was present but after clicking on any email there was no email content shown. A new email came in and the content was shown for that email.

The sent folder still shows all the sent emails.

After looking for solutions on the web, I selected the inbox, right clicked and opened properties. I then selected "Repair Folder". Now, the only email shown in the list is the new email that came in after the issues started.

I have looked for crash reports and it says there are no crash reports.

Suggestions....? Thank you, Peter

Hi

I have a setup with my machine where I use different user accounts for different purposes as this helps me manage a large number of different applications and setups. I want to use the same Thunderbird profile for each of these users as I am the same physical person, these are logical users not different people, and therefore the profiles will never be in use simultaneously.

Research on the internet suggests that this can be done by copying the Thunderbird profile to a globally accesible directory and then using the Profile Manager to point profile.ini to the global profile. I have done this but when I try to launch Thunderbird from a different user I get a message box saying 'Thunderbird is already running, but it is not responding. The old Thunderbird process must be closed to open a new window.'. If I click on 'Close Thunderbird' the message reappears. I have confirmed in the Task Manager that the Thunderbird process is not running.

Strangely, if I launch Thunderbird from the command line version of the Profile Manager Thunderbird launches with the correct profile and appears to work fine. A forum post suggested deleting the parent.lock file in the profile and doing this does allow Thunderbird to launch with the correct profile but then I get error messages saying it could not load the message summary as it's too big.

I have looked at this link here but it's not clear what is meant by 'have each user "move it" using the profile manager'. There is no move option in the Profile Manager (as launched from the command line), just Create Profile, Rename Profile (which I've tried as another user with the same problem suggested) and Delete Profile.

Here is my current profile.ini for the users that won't launch Thunderbird.

[Install8216C80C92C4E828] Default=C:\ProgramData\Thunderbird Locked=1

[Profile2] Name=MarkDevelopment IsRelative=0 Path=C:\ProgramData\Thunderbird

[Profile1] Name=default IsRelative=1 Path=Profiles/uzxtlmbg.default Default=1

[Profile0] Name=default-release IsRelative=1 Path=Profiles/hcw0nqcr.default-release

[General] StartWithLastProfile=1 Version=2

Any help would be greatly appreciated.

I am using Thunderbird 115.2.0 (64-bit)

My Get Messages is grayed out, how do I fix? Not downloading messages I searched the answers for this and tried what was suggested and now the Mail Toolbar is completely gone, the suggestion was to Restore Default setting and I did and now my Toolbar is completely gone

I use Thunderbird email on my Windows 11 computer. My ISP for this is AOL. As of yesterday, 27 Aug 2022, I can not receive email and get this error message "The server does not support the selected authentication method. Please change the "authentication method" in the "Account Settings/Server Settings". My server settings are set to the AOL requirement of OAuth2 and have been working fine until yesterday. My Thunderbird was upgraded to 102.2.0 about the time that I noticed the email problem. Only the incoming server is affected; I can still send outgoing mail. I have the same problem on a second computer that is running Windows 10. Thunderbird on that computer was also upgraded to 102.2.0. How can I fix this issue?

Update 29 Aug 2022 - The above quoted error message from the server goes away if I change the Authentication method for the incoming server to "Normal Password" instead of "OAuth2". When I provide my AOL password (which is valid because I am able to log directly into AOL email) I get this message "Sending of password for user vvchamb did not succeed. Mail server pop.aol.com responded: [SYS/TEMP] Server error - Please try again later." About a year ago AOL required me to change the authentication from Normal Password to OAuth2 and this has worked until the latest Thunderbird upgrade.

Hi, I hope someone can help me.

I'm using Thunderbird Version 102.4.1 on a 7 year old laptop and it's getting to the end of life with numerous driver and non responding problems. Also, it is not compatible with Windows 11. I have linked 3 Yahoo mail and 4 Gmail accounts to Thunderbird on it and they work really well. All are IMAP server settings. I have just bought a new laptop, an early Black Friday deal, and hope to set it up the same as my existing one, so when the old one dies, as it's likely to, I will still have access to the same programmes and emails.

I know I can access Gmail emails direct on any device and they are always up to date - is that called synced? What I don't know is if all email accounts will be synced or the latest - if I use Thunderbird on both laptops. If I delete an email on one device will it be deleted on the other device.

If this is possible, do I download Thunderbird on the new laptop, then set up the accounts for each email and just enjoy from there, OR do I have to copy the profile from the old device to the new one.

I love browsing, streaming etc. but hate trying to get my PC set up or sorting out problems with it. Presume I know very little if you are replying. I have never had two working laptops before so never had to worry about syncing.
