Thunderbird Support Forum

How do I correct my serious error (when tired) in allowing a Thunderbird 'Upgrade' 115.2.2 (32 Bit) Supernova to install on my Laptop (Windows 10 Home, 64 Bit). I failed to read the Release Notes by trusting Mozilla wouldn't issue such a drastic change without Warnings as it was not just an 'Upgrade'! It has screwed up my Set up, Folders etc., completely changed layout, can't find 'Write Message' tab etc. etc . etc.

The previous Thunderbird Version had many problems further introduced by 'Upgrades' but was at least still had continuity with earlier Versions with a functional MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely. N.B My experience in Systems Control, as an Air Traffic Control Engineer, we would throw this out as not fit for purpose.

Help Please and explain how can I revert back to an Earlier Version?

Most of my work life is in email. Over 25 years (starting with Mulberry) I have built up a custom IMAP folder hierarchy that makes work manageable, but Thunderbird 115 has broken this, now displaying nested subfolders at the top level sorted alphabetically. See the images for before and after. For example, there are now three "Administrative" folders that were formerly classified under superordinate folders for my roles as lab leader, graduate program chair, and departmental faculty member. Persons who used to be in Colleagues or Students subfolders are now at top level. Inexplicably, a few folders retained their hierarchy but most are flattened out. Now I need to scroll through hundreds of folders (have not counted recently but in the late 2000's I had over 500.)

I was able to revert to 102.14 using backups, but will be stuck with this version for the rest of my career unless Thunderbird fixes these problems. Thunderbird is so important to me that I make an automated monthly donation to the project, but will have to cancel if this is not fixed.

If anyone has found a work around please LMK. And Thunderbird team, please acknowledge and LMK whether this will be addressed or are IMAP users left behind?

Thanks, Dan Suthers

I am very unhappy with this new Thunderbird update to 115.3.1. Everything being changed is killing my office's productivity. How can I roll back that update to the one before it.

Alternatively, is there any way to make this new update look and act like the previous version. I want all the control buttons back that used to be there.

Since installing Supernova, I find a huge (multiple minute) delay whenever I open a folder to a new tab or window. There was zero delay on the prior version to open a folder, so it appears to be specific to Supernova. I'm surprised that no one else has mentioned it on the forums yet, so it seems it might just be something about my particular setup. Can anyone help me diagnose what I might be doing wrong?

Thanks!

Hello all!

Me and my colleagues are using Thunderbird already 5-6 years. We are very happy with it!

Until Supernova ... It was like a jam full of "flavors" ... however ... All my colleagues use it ( I don't know how?, in my opinion they just don't give a ****, or exist on other planet ) ... except me and one other person.

ON QUESTION !

So on 1st PC updates are disabled in Registry via "DisableAppUpdate" and there are no signs of this Supernova! On 2nd PC is just like this, but on 22.03 thunderbird updated itself! Steps that I made are these :

1. Deleted compatibility.ini 2. Downgraded to 102.15 3. Created distribution folder with policies.json (will copy text below the post) got them from : https://mozilla.github.io/policy-templates/ 4. Renamed updater.exe 5. Created more registry entries /// "AppAutoUpdate"- 0, ExtentionUpdate - 0 6. Uninstalled maintenance.exe

After all this thunderbird is working just fine. I restarted PC several times, made a shutdown - all OK. Until the next morning. And every morning I just added more settings I founded in internet until I ended here. Today is day 4. And same again ...

Please for some help.

Best Regards,

Mozilla has done it again. They seem to be on a mission to ruin their programs. I have already switched away from FireFox, and now I will have to switch away from Thunderbird if I can't downgrade.

I foolishly upgraded to 115.5.1. The new interface is more cluttered and takes up about 30% more space than the old interface. The bar at the top is wider, the bar between the email list and the email contents is wider. The side bar on the left which lists the folders is wider. And all this is happening even though I have "density" set to maximum. Furthermore, my favorite add-on is suddenly no longer working and I can't find a way to restart it.

What I need is this:

• Please tell me which version prior to 115.5.1 is the most stable and doesn't have any of the interface changes that 115.5.1 has. (How do I find out the number of the last version I was using?)

• Please give me detailed instructions on how to download such version and downgrade. I am NOT a computer person and I need clear instructions.

Thank you.

I hate the way the new Thunderbird version looks, can't get normal number of emails at once, can't read any of them at the bottom of the page. Please give me my old version back. This was a horrid intrusion with no warning that it wasn't just a normal update

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

This is the best I can do to get back to a usable User interface after v115 automatically installed and completely removed the ability to get messages etc. The problems that remain that I can't solve:

Mozilla Help is silent on these issues:

See third image named broken UI 1) Using the three dots I could get rid of the bright blue "New Message" button but I can't get a matching bright blue "Get Messages" button to go with it even though the option for a get message button is enabled in the ... menu. Unchecking that option seems remove the tiny gray meaningless thundercloud icon that isn't labeled to tell us what it is if you even happen to notice that tiny meaningless icon even exists. I clicked the option on and off several times before I could tell what changed. So I'm forced to use the new customizable tool bar that is located so far up it has no association with email at all. My number 1 question is: How can I get a get a nice labeled "Get Messages" Button just like the "New Message" Button in this location?

See second image named swap menu bars 2) The new customizable menu bar v115 brought is above the real menu bar that has always existed. Customizing that by putting buttons on it was the only way I could even get buttons equivalent to what v115 totally removed. Unfortunately it is located where the windows Title Bar should be located and I can't find a way to move it down. My number 2 question is: How can I move the new customizable tool bar menu down below the classic File View Edit menu that also gets used a lot.

See first image named gray bubbles 3) Notice the new gray bubbles with a number in them. The only options I can find add other numbers in addition to this. My number 3 question is: How can I get rid of the new annoying gray bubbles with the meaningless number in it.

Thunderbird 115.2.3. Mac OS 10.15.7 on an older Mac mini. I use larger-sized fonts, so display real estate is limited.

I want to see the full headers, but I want them to scroll in a message header pane that I can resize (that is, I want to be able to move the horizontal line pointed to in the attached image to increase the message display area and decrease the header display area). Otherwise, it takes over my entire message space. Is there a way to do this (I haven't found it)?

Like many others, I'm seriously considering going back to v112 because I find SO many of the changes in 115 "change for the sake of change," "fixing" things that weren't broken, and breaking functionality that we thought was stable. Not keeping thins like the default font that was selected in the previous version before the upgrade is just plain annoying.

I use Thunderbird to manage many email accounts across different profiles. Not all accounts show up in unified folders, although all accounts are visible in the "All folders" view. Is there any way to "reset" anything to fix this? The Unified folders "Inbox" view in 112 was the best way to see all accounts that had new messages.

I have used Thunderbird for years. I recently updated to version 115. I prefer the previous version. In 115, I cannot zoom a page simply with ctrl-+ without first going to the view menu. My two Outlook inboxes are sorted at the bottom of my list of favorites and they cannot be moved up with my other inboxes. I had no problems with the previous version. How can I get and reinstall that version?

I have been using Thunderbird like Forever. Just downloaded for my new computer (Windows 11). Version 115.3.2 I HATE this new format. I have read other complaints about this with the question How Can I Get The Old Format Back? That question is never answered. I want the main space back on the majority of the screen. Now the majority of the screen is taken up with a list of messages with only a small box on the right for the actual message. I Hate This. If I can't get back to the old format I will probably have to go to some other e-mail program, and my donations will go with me!!!

Hello,

till today's Tunderbird-Update it was possible:

- click on the Windows Notification - => directly brings you to this email

With new Thunderbird that's not possible any more. For me this is an absolute showstopper. :-(

Is there any way to change this and bring back the old behaviour?

Thanks a lot for any help!

I had version 102:15:1 up and running after I had new terrible version 115 removed. Now during an update TB/Mozilla reverted me back to 115. Now I do not seem to be able to downgrade back to 102:15:1 again. WHY Help would be gratefully received. Thanks

Thunderbird 115 forcefully migrated my older profile and did NOT leave a way to go back?

That is NOT the way to do this.

You need create a NEW profile for the NEW version and LEAVE THE OLD PROFILE ALONE!

You must also have an alert, and explain the process, transparently giving the owner of decades of e-mail the opportunity to safely upgrade AND have the opportunity migrate back if they so desire.

How DARE Mozilla treat users and their data so casually.

This is NOT the way to do this.

Currently FURIOUS that this trusted tool has left me NO way to downgrade back to 112 except to rebuild my profile (and all the various e-mail accounts) from fucking scratch.

Hi,

I hope you are doing well. I am completely blind. I've been facing a problem with thunderbird. Whenever I try to sign into gmail, it says unable to log in, probably wrong configuration, username and password: This is in spite of the fact that I've used my correct password multiple times, I did a double check by signing in and out on the web multiple times to confirm. My email is muhammed3198@gmail.com I also checked my settings to see if imap was enabled, which it is. Please help and fix this issue as urgently as possible. I even selected configure manually to see if all the configuration settings were correct, and they seem to be, like the ports, the incoming and outcoming settings, etc. Please help. Best regards, Muhammad.
