Thunderbird Community Forum

I've been on Thunderbird for almost 20 years and a Mozilla fan. Have evolved a fairly elaborate configuration of local (POP) email folders, rules, calendar, and accounts to manage & organize email activity, retention, archiving, etc. I've not had to deal with Profiles in previous upgrades and don't have much experience with it.

The recent Oct 1 push of Firefox & Thunderbird 131.0 releases took me by surprise. I was able to re-implement the previous Firefox profile to recover bookmarks, cookies, passwords, etc. However, when T-Bird warned that 131.0 was Beta & unsupported I took the suggestion to download & install the current supported release: 128.3.0 (I was on 128.2.3). Then hell came.

Once downloaded, installed & launched, Thunderbird 128.3 cautioned the new profile created with T-Bird 131.0 was incompatible with previous versions and that I should create a new one, which I did. Still could not get new T-Bird to recognize previous profile, so I tried uninstalling, downloading & reinstalling 128.3 multiple times, each time prompted to create a new profile before proceeding. I tried to follow the previous profile restoration process detailed on support forums & articles, but none seemed specifically relevant to my situation.

I located my profiles in the appdata roaming profile folder, including what I think are most recent based on size of mail folders. Can't determine whether I had just one or several in use due to the extent of my setup. Could really use some help & advice to: 1) Determine which profile was in most recent use prior to T-Bird upgrade. 2) Whether more than one profile was in use. 3) Re-implement the profile I was using on T-Bird 128.2.3 with my new 128.3.0

Regards & many thanks in advance, John C Houston

PS You'll ask why I would upgrade to 131.0 from 128.2.3. Answer: it was on auto-update and 131.0 is what was pushed. No more auto-updates for this guy!

I have installed T'bird in a new replacement pc and also added my two accounts. However, I now need to include my many Local Folders using Profile Folder information from the old pc.

Should I delete all the account information I have installed in my new pc T'bird prior to installing the Profile Folder copy? Thanks Ron

Hi all,

as per subject, with Thunderbird 128.3.0esr in Multiweek and Month calendar views I can't move elsewhere an event with drag & drop, while I can do it in Day and Week views: am I missing anything?

Many thanks

Dear Thunderbird team I am an avid user of TB (home desktop Windows PCs), but I have been resting on my laurels on v78 for a few years now. I know, shame on me. I would like to upgrade to a stable "modern" release (emphasis on "stable" please). Can you please advise if I should aspire to end up on 115 or 128, and how I might get there ? From reading some older blogs, there is advice that says.... first go to v91, then v102, then v115, and so. That seems a bit tortuous, but I am happy to do so if that is still the recommended approach.

Also, can you advise on how I manage my Profile through all this, do I need to do various exports/imports as I move through these different versions, etc.

Many Thanks

Tried linking newly installed Thunderbird to an existing Microsoft account, It won't accept my existing Microsoft username (email address) and password, which I verified were correct.

I'm running for quite a time Thunderbird on Windows up to Win11 without any problem. For about 3 years I'm using the same TB profile in dual boot environment with Linux Mint (v21 until last week and now version 22). I understood why I didn't get access from Linux side after the latest TB update in Windows as obviously the file structure and other things had changed to make it incompatible to elder versions.

However, as Linux is now my normal working environment, I've tried it again after upgraded my system to Linux Mint 22 Cinnamon 6.2.9 , kernel 6.8.0-44-generic and failed again, having the same error message when starting the profile: "Thunderbird is already running, but not responding. To use Thunderbird, you must first close the existing process, restart your device, ore use a different profile. "sudo killall Thunderbird" didn't find a running process.

I've tried importing everything in a new profile, which worked (more or less), but failed with all attempts getting access to my local profile. A local profile appears after importing but contains no data, trying to import its data separately doesn't trigger any error message when just ticking "E-Mail", but nothing is imported. When ticking "E-Mail" and "Settings", I'm getting a red alert that asks me to look into the error console which doesn't help either.

What can I do ????

A recent Windows update on my Dell laptop resulted in an unusable copy of Windows(thanks Microsoft). After much time and effort, Microsoft's only solution was to do a fresh install of Windows which we did. Of course all software and apps had to be reinstalled. I have used Thunderbird on this laptop for years successfully. I downloaded the most current verision of Thunderbird and installed it. I then attempted to add my email account. I entered my name, email account name, and password. Message came back, "Configuration found in Mozilla ISP database." Configuration shows Incoming: IMAP, SSL/TLS. Outgoing: SMTP, SSL/TLS. I then clicked on the "Done" box. Next an Xfinity window opens with my username. The next box says "Let's go". I clicked that box. A window pops open that says, "ACCESS DENIED, You don't have access "http://login.xfinity.com/login" on this server. I googled that line and found many responses. I tried many of the solutions shown to no avail. I then contacted Comcast/Xfinity. After hours on the phone and finally reaching Comcast Assurance Level 2, the agent and I tried various things and still to no avail. So, here I am. Anyone there have any ideas on how to proceed. Thanks to anyone who tries.

I see my particular problem has been ongoing, but it's the first time for me.

After latest update, 128.2.3esr, I can only see and access one email, the last one that arrived to the folder. None of the fixes I read about have worked for me. Once I watched as several emails arrived, they appeared one by one, then disappeared to make way for the next.

Can you suggest anything? Following one list of instructions, I made a link to a pastebin page. https://pastebin.mozilla.org/VQJJM8Md In Troubleshooting mode, TB looks more or less as I expect. That is, I can access all emails. There was another question to answer, but I lost the conversation while rummaging around.

Should I continue to work on this, or wait for the next update? In the meantime, I am emailing from my Earthlink page, but I really prefer TB's flexibility.

Thanks for any suggestions.
