Thunderbird Support Forum

I tried to update Mozilla Thunderbird to 115.5.0. Now I can not receive emails on my computer. The message I received said, Error: Platform version 115.4.0 is not compatible with version 115.5.0. How do I "return" to 115.4.0 so I can have access to emails on my computer? I can receive emails on my cell phone. Thank you.

Every few days, the index pane of some folder gets corrupted. Repair (right-click, Properties, Repair Folder) fixes it. Then a few days later this repeats, with a different folder. I have three IMAP accounts and this occurs on more than one of them.

Any suggestion for finding and fixing the underlying problem?

Upon reopening Thunderbird mail today, I find that the latest update does not allow emails to be opened in a new window with one-click. Clicking on an email launches the message in a new tab instead of a window. Why create a new issue like this? DUMB . . . please fix.

Hello,

I regularly move my emails to local folders. Today, after updating to version 115.6.1, hundreds of emails in one particular folder appear completely blank, without subject, correspondents, or content (see picture). The rest of them are fine.

How can I restore the content of those emails?

Or maybe it's just a bug and they're not "real" emails. How do I know for sure?

Cheers!

After clicking the Thunderbird to enter my email the whole system goes through connecte3d to uepat624@gmail.com then up comes a message from Thunderbird indicating "you may have too many cached connections use IMAP Advanced Settings to reduce cached connections" Then things continue on for probably 5 to 10 mins. sending login info, looking up IMAP, checking mail server capabilities, looking for folders, sending login, opening folder box, downloading

Eventually email inbox and messages come up. I can send, receive and send mass mailings but when you read a message and want to go back to the inbox you have to scroll all the little boxes at the top of the screen back to the one that says "inbox".

I need someone to remove the cached connections. Pat Blackburn

When I try to add a link by using Ctrl + K, the email draft essentially crashes. If I click on the email that I was writing, it dings/chimes. The email that was in progress is gone. It cannot be changed, does (did) not save as a draft, and cannot be closed.

Other aspects of Thunderbird continue to work, and I can write a new email. However, to get rid of the email that was in progress, I need to shut down the app. Restarting the computer does not get rid of the problem.

Any thoughts or suggestions?

Hello, Unfortunately after last updating to supernova Thunderbird very often freezes/crashes (several times a day). Is there any solution to this problem. I'm using version 115.4.2 (64bit) on Windows 11. This happens in several work stations.

Best regards Baron Paweł

Hello,

I am using Thunderbird 115.4.2 (64-bit) on Win10. Some of my emails have those subjects are not readable as image attached. They are supposed to be chinese charaters. In " View Source" choice, they're displaying correctly. But I tried " repair text encoding" didn't work.

And in my Font Advanced setting, it's searchable that there's encoding. But I cannot see it in my interface. If someone could share how it can be fixed?

Thanks.

Been using Thunderbird for years, seldom have problems. But starting to see the software frequently hanging in the last week or two. Most often, things will be fine, and I'll go to bed. When I wake up, the software is hanging, no messages have been downloaded for hours, the cursor is a small blue spinning circle, and the program is not responding. I have to force-quit with task manager, start it up again, then it runs fine for several hours, before doing the same thing again. Just now, I found it hung again, without having to go to bed first.

I have no way of knowing if any email is being lost during this time or not, but I have no reason to think it is. The problem is not anything major (force quit, then reload is not a horrible inconvenience), but I'd like to avoid the problem.

Only recent change is I created a new gmail account because one place I like to receive emails from seems to be having problems with my own domains' emails, but they don't work with the gmail account either ... go figure. The new gmail account seems to have no problems sending or receiving emails for the most part, but since this problem started happening within the last couple of weeks, and I added the new email in the last couple of weeks, could be connected.

Hello, After update Thunderbird quick filter became very very slow.

If you type in quick filter field two words. At the beginning is being shown random results not connected with typed in words. Then in 30 seconds or later are being loaded correct results. Not possible to use like this. It's local search on normal PC (with CPU AMD Ryzen 5 PRO 4650G, 24GB RAM) filtering must to work fast. Could you fix that issue?

Thank you

I work with my tabs a lot. When I open an attachment, Thunderbird opens a new tab and buts the content of the attachment (pdf) into a new tab. Often I need to save my work and stop working that day, and just let my computer go into sleep mode with Thunderbird still open in windows. In the previous versions, I could just start working the next day, and all my tabs are populated with the attachments and information I left open the day before. With this new update 115.4.2 (32-bit) it does not retain any of the information in any of the tabs that were previously left open. It only happens when the computer has been sleeping overnight or for an extended period of time. If I put the computer to sleep and then wake it up pretty quickly it keeps the tabs just fine. Very frustrating

Runs normally fast on my external monitor, but not on the laptop's internal display where it's really slow. In the beginning seconds of using mail, it runs great. But then after a few seconds the graphics are running slow. Mousing around, switching between emails, etc. - basically any interactions with the UI are really slow, makes it barely usable. But why is it that when I'm connected to an external monitor, things run ok?

New installation of Thunderbird on WIndows11 - cannot send mail - get the follwoing error message: "outgoing server smptgo.lanlime.com failed. The server may be unavailable or is refusing connections. Please verify that your outgoing server SMTP setttings are correct." WHERE DO I LOOK TO FIND THESE SETTINGS///

I check 7 different email accounts. Now when I check them and click on an email the whole section will go to the top or the bottom, Then I need to scroll down or scroll up to get back to the new emails. And different email accounts do different things. I use Windows 11 - 64 bit. I've really liked Thunderbird over the years, have contributed so I hope these flaws gets fixed. It's just so problematic to use it now. I don't have the time to spend hours searching through threads to find if it's even fixable.
