Can someone please give me some troubleshooting tips on the Thunderbird email client on Windows 10?

I am running version: 128.1.0esr (64-bit) on Windows 10, and it started a very annoying hang / non-responsive behavior recently, and updates do not fix the symptom.

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick

Although I have my email trash folder set up to keep trash emails until I decide to manually remove them, many or most of them disappear as soon as I click on the trash folder. How do I fix that so trash emails aren't automatically deleted?

Hi, I am using windows 10 pro and i use thunderbird for my emails. Can you please tell me how i can easily backup to a usb and how i can check if its done correctly? Thank you

Hello,

I've been using Thunderbird for quite a long time now. I manage two private mail accounts, one at t-online and one at GMX, with Thunderbird. Suddenly, since yesterday I cannot longer get access to my GMX account. When opening Thunderbird, I first get a popup requesting to enter my password for the GMX account (normally I needn't do that). When I enter the (correct!!) password, it is not accepted, and I get an error notification (see attached screenshot). "Try again" also does not help.

The t-online account I can operate in Thunderbird as usual.

What can I do to again get access to my GMX account via Thunderbird?

Thx and best regards Rainer

Hi, My wife and I have both been having trouble getting emails from Fasthosts. Have to click "get mail" many times, and eventually they download. No problem with Mailwasher or on Androids. Win 10. TB both 128.1.0esr

On 31 July, a day before the Thunderbird update from V115 to V128, the emails in my inbox no longer had reply or forward options and were addressed as coming from me as well as to me.

A yellow message at the bottom of each email read: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity Marcus Relton <my email address>"

My email provider thinks Thunderbird mistakenly believes these emails to be drafts. I have added on FolderFlags, which now has a V128 version since I first experienced this problem last week.

I am supposed to be able to right-click the inbox, go down the drop-down menu to properties then see another dialogue box but this isn't appearing.

I can only reply to or forward emails by right-clicking in the message in the inbox and I can't click on links in the email. I have to open the link then cut and paste them.

Mail.coop, here in the UK is trying to find a solution, having hoped FolderFlags would work, but if anyone has any suggestions, please share.

I saw someone had a similar problem with their drafts folder in April but the suggested fix didn't solve it.

Thanks,

Marcus

I'm having trouble logging into my Gmail account using Firefox. After entering my username and password, the login process either freezes or displays a 'Something went wrong' error message. I've tried clearing the browser cache and cookies, disabling extensions, and even updating Firefox to the latest version, but the issue still occurs. What could be causing this problem, and what steps can I take to successfully log in to Gmail through Firefox?"

Deleting msf files does not solve the problem. Turning off windows firewall (a bad idea) does not solve the problem. I don't want to swich to a new mail program after years of using Thunderbird. Can anyone help?

Hi. When I view the Activity Manager, I see many log entries similar to the following except with different folders: "The current operation on 'Kailah' did not succeed. The mail server for account xxx@gmail.com responded: [NONEXISTENT] Invalid folder: Financial/Venmo/Kailah (Failure)." The folder in question existed a long time ago and has since been deleted. Same for all the other similar messages. The folder(s) was / were originally created in Thunderbird and then deleted after many months. If I create the invalid folder in Gmail, the message no longer logged. I reboot the computer daily and every day these messages appear. I am assuming something is out of sync and Thunderbird believes these folders exist. What can I do to remove these issues. Server type is IMAP Mail Server. Using Thunderbird 115.14.0 (64-bit)

Thunderbird 128.1.0esr takes more than six seconds to open an email or to delete an mail. Thunderbird is totally unresponsive and frozen during this delay time. This is very bad. I have taken all steps to ensure that my installation is not the reason. The previous version of Thunderbird was even worse. This still remains unusable. As the final measure, I even tried 'view message body as plan text' but this did not cut the time either. If the email is opened the first time, this delay occurs. If the same email is re-displayed again later, the delay does not occur. The delay always occurs when deleting an email. Opening the Mozilla email address certification mail from you guys to create a Mozilla account took more than 10 seconds to open and display. I am running Windows 11 in a VERY fast machine. I hope there is a solution; if not I have to find another email software. The delay also happens if Thunderbird is started in the debugging mode (shift-click).

In June, bluemenofmorocco@gmail.com no longer sends or receives email via thunderbird. Other Gmail addresses keep working via thunderbird. Says authentication error. I recall I had to set up a password with Google on my Google account. My daughter says this happens sometimes a third party access issue. I don't recall this earlier password to Google years ago. Thank you for your help.

I usually work with my computer hardwired to my router. For some reason, this is not working anymore and now I have my computer connected via wifi. As soon as I changed from cable to wifi, Thunderbird started to ask permission to connect to my Google account every time I open Thunderbird. Sometimes I have to grant permission several times. At some point, it stops and I can keep on with my work until the next time I restart my computer and open Thunderbird. Then the cycles starts all over again. Any ideas¿?

Questions re Email Inbox and Reply window:

1) I can't find a list here showing the Inbox icons and what they mean, specifically this one. I can't delete it, nor do I see anything in the inbox list of column indicators that it might be. I'd like to know what it's for and if/how it can be removed.

2) I want to have more space for the message pane; the only way to do this is to have a smaller font size for the email List pane. I don't see where I can change this. Is it possible to decrease this font size? I've tried but haven't t been able to locate info on this website.)

3) Reply font: I keep changing it to my Preference, but it keeps going back to a default.

Also, find it annoying that I can't select a specific font SIZE. I've never seen a Windows desktop software of ANY kind, not just email, which doesn't give have choice of font size as well as the font itself. Is there a suggestion area on this website?

Thanks.

When I open T bird in win 10 or 11, it takes a couple of minutes to scan all my email accounts, during which time the program is too slow to be useable. Is there a fix for that?
