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MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely.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?

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.

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 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?

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 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

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!

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

Version 115.3.1 (64-bit) has got to be the worst thing I have ever seen. I cannot downgrade because now my email inbox has been formatted into a new format. Anyway to get back to the previous format, or am I back to using my ISP webmail?

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

Since yesterday, my Thunderbird upgraded to the latest 115.3.1 (64-bit) from the previous (perfectly working) 102.15.1 on macOS Ventura 13.5.2 (MacBook Air Retina, 13-inch, 2019).

The new Thunderbird 115.3.1 works for me only in Troubleshooting mode. Once in Troubleshooting mode, I removed all the Add-on, themes, dictionaries, language packages, etc., and restarted. I also removed two of the four email accounts I was accessing without a problem with the Th.102.15.1 version. I left only my primary email account (Outlook with IMAP) and Gmail, both working with security SSL/TLS and authentication OAuth2.

Still, when in normal mode, Thunderbird 115.3.1 gets stuck on 'Sending login information' and freezes.

I spent at least four hours between yesterday and today looking for solutions, but none is working.

Please, help me to fix the problem.

I have used Thunderbird massively for work since ever, and I'd like to stick with it, but this new release is giving me a hard time!

Thank you

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)?

Please restore my old version of Thunderbird - at 85 years I am not computer savvy and I am too old to learn new tricks. So please tell me how I might get back the previous layout of Thunderbird. Kind regards, Lawrence (Laurie) Ford. Melbourne Australia. 2nd October,2023.

How do I downgrade to an older version of Thunderbird on Rocky Linux (RHEL clone)?

For my last update (yum update -y) I got Thunderbird 115 which has lots of problems.

If I try “yum downgrade thunderbird”, I get the error: Last metadata expiration check: 3:43:41 ago on Tue 14 Nov 2023 04:57:52 PM EST. Package thunderbird of lowest version already installed, cannot downgrade it. Dependencies resolve

I downloaded: https://archive.mozilla.org/pub/thunderbird/releases/102.9.1/linux-x86_64/en-US/thunderbird-102.9.1.tar.bz2 but when I unzip and click the thunderbird icon, Thunderbird doesn’t pick up my Thunderbird profile. I saw some windows downgrade tutorial that said to delete compatibility.ini from profile but when I deleted compatibility.ini Thunderbird still doesn’t pick my profile.

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!!!

I am not receiving my hotmail.com email now after this latest update to 115.2.2. This is a real problem, I get a popup window about Microsoft not being able to sign me in...? What the heck have you done to me with this update. I want to go back to my previous version, but I can never find any info on how to do that and I am not positive what version I had before this Supernova edition. This new one has caused me a big headache that I really don't have time for. Pease advise how to return to version 102.? ASAP
