Thunderbird: форум сообщества

Enough is enough—every update brings problems, crucial add-ons stop working, and now drag and drop attachments have stopped working. It's really inconvenient. Maybe it's time to stop this nonsense and implement paid subscriptions or purchases, but in a way that makes everything work.

I'm running Thunderbird on Mac OS 15.3. I have two POP accounts in Thunderbird; the configuration has been stable for years. This evening, I went to add a new account, and Thunderbird seemed to have decided to update itself, including flipping me over to Chrome where it opened a page about Supernova.

Thunderbird relaunched and came up with an empty "Chat" window. My usual mail window is gone -- and I can't get it back. I can't get an "About Thunderbird" window to open.

I actually can't figure out what happened. My mail appears to be gone. My accounts seem to be gone. I can't open Settings, I can't open Account Settings.

Wait, the mail accounts seem to still exist -- I can tell Thunderbird to check mail, and the POP server shows the checks happening -- but if I send mail to myself, nothing opens. Also, all of the Layout menu options are greyed out.

Help? :-)

Thanks, Vince

Your latest request for donations has evidently come with a forced upgrade which I did not authorise. I have been happily using an older version of TB because it supports my add-ons and themes. Now because of your uninvited intrusion they no longer work. Furthermore it seems that I can no longer download an older version that supports my requirements. NOT HAPPY!

There must have been an update for Thunderbird that screwed up the way I have been using Thunderbird for years now. I had sub folders under inbox. For example, I had an investment newsletter go into a sub folder under inbox labelled "inv". I had a filter set up to move emails that had the name of the newsletter in the title to go to that "inv" folder. In this new version of Thunderbird, those separate sub folders are gone. The filters are still there but the folders are gone. Now all emails just go into the inbox. Is there a way to roll back to a previous version?

TIA Eric

I didn't know there was a non-ESR version of Thunderbird until I found out by chance a few days ago! Since the latest update to ESR 128.5.2 has crashed 11 times this week, I would like to move to the latest version (64 bit?) non-ESR. There must surely be an official Mozilla step-by-step guide to doing this?

Ever since Version 146 was automatically downloaded, all I see is a blank page and several icons across the top representing individual mail. (See pic attached. Before 146, I saw all my mail listed.) The program freezes; I can't click on any icons. Most of the time I am just waiting for something to load. I have to fight to get my folders to even see my mail. How do I get Version 145 back?

I recently changed onto the new release channel by installing version 136. I now find that this new release channel appears to have installed version 138, but it is reported as a beta version. I do not want to use beta versions, as I am having a lot of problems with it, so how can I return to a stable release?

Since updating to 141.0 64 bit today (Jul 22, 2025) my addon Filtaquilla is disabled.

I tried another attachment saver and the same thing happened. Okay, I'll revert back to previous version.

Can't do that without starting a new profile.

Sure glad I donated to Thunderbird last night.

My local folders are missing. There is nothing in my profiles to recover from. This is the second time this has happened after a Thunderbird update. Last time the local folder were found in my profile and I was able to restore them, This time there is nothing to restore. Has this happened to other users?

Hello, I have Mozilla Thunderbird version 128.12.0esr (32-bit) on a Windows 10 laptop On the Help/About Thunderbird it says update failed. I have clicked on download and have version 139.0.2 in my downloads folder. When I try to install it all goes well until I get a message "Your computer must be restarted to complete a previous uninstall of Thunderbird. Do you want to reboot now?

Yes No " I have rebooted several times now with the same results. What do I need to do to get the update Regards Peter Norris

Could someone please tell me what the latest version of Thunderbird is on the Release Update Channel? I am on version 139.0.2, and when I check for updates in the app, it says that Thunderbird is up-to-date. Is version 140.0 not going to be available on the Release Update Channel?

Hi Guys,

Thunderbird version 128 is missing in the release page - https://www.thunderbird.net/en-US/thunderbird/releases/

Do look into this.

Hello,

I'm confused and slightly concerned.

Through no deliberate action by me, Thunderbird DOWNGRADED itself from the May 2026 standard release version to an AUGUST 2025 ESR(Extended Support Release) version.

UPDATE: the next application restart brought the ESR version up to date, but why was I forced onto the ESR version?!

What could have pissibly triggered this? I don't want or need ESR, and without knowing the cause, I have e no guarantee it won't happen again. Worst if all, everywhere I look, there is zero explanation for this. It appears to be fairly unprecedented.

My original installer for 102.15.1 was downloaded from the official Thunderbird site in 2025.

The sequence of events:

• I've had Thunderbird version 102.15.1 installed for awhile, but wasn't using it.
• Ysterday I opened it and connected an account.
• Today I noticed it hadn't auto-updated, so I went into the settings and clicked on the 'check for updates'.
• this brought it up to v115.10.1.
• Its success was demonstrated by me being sent to this URL after it opened: https://www.thunderbird.net/en-US/thu.../?locale=en-US&version=115.10.1&channel=release&oldversion=102.15.1(https://www.thunderbird.net/en-US/thunderbird/115.0/whatsnew/?locale=en-US&version=115.10.1&channel=release&oldversion=102.15.1)
• An hour later, I closed Thunderbird completely hoping it would fix a sync that appeared 'stuck'.
• When I re-opened Thunderbird, I saw the small "updating" window. It was pretty surprising since I had *just* updated.
• After Thunderbird opens, after this additional "update", the URL that I'm sent to is this: https://www.thunderbird.net/en-US/thu.../?locale=en-US&version=128.14.0&channel=esr&oldversion=115.18.0(https://www.thunderbird.net/en-US/thunderbird/128.0/whatsnew/?locale=en-US&version=128.14.0&channel=esr&oldversion=115.18.0)
• Thunderbird changed to a year old ESR version!

After updating my Thunderbird mail application from version 128 to 140, the shortcut icon for composing a message is no longer responsive and I cannot create a new message from it. I can no longer create a new message without right-clicking on a sent email and using “Edit as New Message (E)”. How can I get back to being able to create a message from the message creation shortcut?

I have been trying to stay on releases and was told to upgrade to 115.10.1. So I did that and was told to go to 115.18.0 and it was not noted as esr. So I did and was immediately told to go to 128.8.1 esr. I was not on the esr channel and do not want/need to be on esr. about:config has been changed to esr channel from release w/o my ok - the least I'd expect is a warning. Release 115.x.x has betas and releases more than I had seen previously - aboutr 25-26. It looks like nothing but betas from 116 to 128 and a lot of what look like releases from x.0 to x.10.2 which is new to me. What is the rational behind all these versions and why there is not a simple center of how to use this info? I remember when way back, tbird had issues but they were manageable.

Greetings! I downloaded Thunderbird for my new Win11 desktop, but it gave me an ESR version 128.9.1. It's working fine, but can i just move to the current 137.0.1 version? If so, how do I do that - just grab the current version and install on top of the ESR or should I remove the ESR first? Thanks in advance!
