I-Thunderbird Community Forum

Tuesday Oct. 7, our ISP converted to a new e-mail program. I could NOT log in/on I called our ISP's help desk. The 'technician' could not help me log in to our Thunderbird POP 3 account. He had me, WITHOUT asking if I had essential - legal - medical-etc. e-mails in the IN BOX or in folders! He NEVER warned/cautioned all ?would? be lost - GONE.

I URGENTLY need to recover all TB POP3 IN BOX & e-mails in folders. I need to access legal messages today, if possible.

If Mozilla does not have a recovery program, what do I do? I am not seeking to recover ' deleted messages (unless his having me change from the POP3 account to a 'new' IMAP account is the same as ' "delete" '.

Any & all prompt responses APPRECIATED! Remain WELL & Be SAFE!

Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

For account dhoule@formatio.info I have following folders: Courrier entrant Brouillons Modèles Messages envoyés Tous les messages Spam Corbeille Important Suivis

When I receive a message, it goes into Courrier entrant, Tous les messages and Important How can I stop this behaviour (or how can I reduce the number of folders under this account? Merci Daniel

We have poor eyesight, so in vertical display mode, we could really benefit from having grid lines (at least horizontally) to visually distinguish each message. We have read various solutions on the Internet, but none seems to work at least not in dark theme mode, which is the default for a great many people with vision impairments (or just plain tired eyes). Perhaps some solutions that once worked have been uprooted, so to speak, during the course of Thunderbird updates.

We are used to having grid lines in Outlook (desktop). We are currently exploring switching to Thunderbird, but it needs to support our vision needs. For us, this capability is fundamental, not optional.

We are comfortable making config entries, creating and working in userChrome.css, and the like. We would be grateful for any guidance in this regard.

Thank you kindly!

Hello...I'm currently having a problem with Yahoo Mail having too many messages in the account, and as a result, I cannot receive new mail in my Yahoo account. It was suggested to use Thunderbird to download everything from my Yahoo Mail account. I've downloaded Thunderbird, set up the server parameters as instructed, and it appears to have downloaded (synchronized) everything just as it appears in my Yahoo Mail account, via iMap. I would like to currently (temporarily) stop Thunderbird from downloading and synchronizing with my Yahoo Mail account so that I can sort through and delete/save/organize what's been downloaded into Thunderbird, and delete everything in my Yahoo Mail account so that I can resume receiving new mail messages in my Yahoo Mail account. I like the Thunderbird app so far and am considering using it as a one stop app for all of my online email accounts...Yahoo, Gmail, etc. I apologize for taking up time and space for this question, as I'm presuming it's something pretty simple to do, but for some reason, I'm just not seeing how to do this in Thunderbird Settings. Can someone please guide me on how to do this? I used iMap to download/synchronize my Yahoo Mail with Thunderbird. Thanks in advance!!

I have an email account through Moxilla Thunderbird and I can only access earlier emails through the webmail account. I want to be ble to see ALL my email messages by clicking on Moxilla Thunderbird icon on my computer. PLEASE HELP!

My email window changed and I don't know how. The 4th column after - date / subject / correspondent being the "Reading Pane" is no longer visible. "Message List Header" doesn't show in settings and neater is table view showing I'm aware of a item at the bottom that can be dragged up but it covers the list of folders.

My thanks again to sfhowes, Rick and others for assisting me to get back my ability to once again send e-mails from Thunderbird. Now for the next step.

Just days ago, I migrated my years of Thunderbird e-mails on a POP protocol to IMAP. Before doing so and before also uninstalling my old Thunderbird because of e-mail sending problems and then reinstalling a new version, I saved a profile. Now with the most current version of Thunderbird, I lost (i)a decades worth of saved inbox e-mails (but for the last 2 years), (ii)I lost all of my sent e-mails but a few odd ones, (iii)I lost my archived e-mails in Local Folders and (iv) I lost all of my contacts and saved group e-mail address lists.

My profile is saved on an external hard drive. Obviously the new installed version of Thunderbird must have somehow found the last 2 years of my inbox e-mails but nothing beyond that as mentioned above. Can you share please a recommended procedure where I can better import what I assume I saved correct on the profile I saved twice (I saved a master folder named Profile and separately saved 4 folders - 2 folders ending in default and 2 ending in default-release. Thank you.

I am buying a new PC. I would like a 'blank' TB on this machine so I can replan the folders and the email address books. I'd like the current copy on my current PC to be moved to the new PC such that I can access it as I do now but- like a 'sleeping' copy - ie just there to access the emails and address book occasionally/when needed, but not receive new emails.

This will give me a fresh start on the new TB on a new PC, and will save me having to clean up the old TB version. Is this possible? Thankyou

Hi, how do I get rid of

"Error: Platform version '143.0.1' is not compatible with minVersion >=141.0 maxVersion <= 141.0 Maybe try to reinstall Thunderbird?"

It's not very practible to do a new copy everytime a Thunderbird Update has to be made because I mainly store my emails in a local copy (respectively a lot of copies already).

could you please help me?

Thx & BR Eva

For some reason (accidental key stroke?) one of my email account's folders are no longer arranged alphanumerically. How can I reset the order to alphanumerical? I can't find a menu item or setting to do this. Thanks

I am a M365 - leaver, and working several months now with Thunderbird/LibreOffice/Nextcloud. Sometimes I'm proud of what I learned and can do with the new software. Sometimes I'm a little lost in the woods.

I'm using the add-on Quicktext to insert default html text, like a template, in some of my my emails. One of the templates is a notification for my customers to inform them the invoice they received from me is not yet paid.

In the former software I was used to click in my template on a datepicker to insert the senddate of the invoice. I tried to insert a html-datepicker. This appears in the email, but is send to the reciever as a datepciker, not as the date I choose.

My question. Is there a way to insert a datepicker in a template like Quicktext, or is there a better add-on for this goal?

Hi, I am experiencing an issue with adding my IONOS email accounts in Thunderbird version 143.0.1 (64-bit). I have a total of three email accounts connected to my IONOS service provider. While I have successfully added email accounts in the past using Thunderbird, I am encountering difficulties with these specific IONOS accounts. When I attempt to add my account, the process gets stuck at the 'Configuring email' stage without providing any error code. I have already contacted IONOS support, and they confirmed that the email accounts are functioning correctly on their end. Given this situation, I would appreciate any assistance you can provide to resolve this issue.

Hello, I sent the message below last evening and someone named "Ed" replied. Thank you Ed. When I tried to "reply" to his/your question/email, I immediately got a bounced back email as "no-reply@support.mozilla.org" could not be found. Also, in my original question I said that I'm not "computer illiterate"; apparently I am as I don't know how to reply to his question. Please include info on how I can respond. So, I'll start all over by sending my original question:

Hello, Attached are the messages I have been receiving ever since 6 October 2025. I've tried to read about fixing these myself, to no avail. (I mean, I can Read; I just can't fix this.) I've tried to Compact ALL folders individually. But that seemed to do nothing. (Before 6 October, the Thunderbird window would at least "flicker" a little after compact.) Trash is empty. Tried disabling McAfee AntiVirus & Firewall. And, no, this isn't happening because I'm using McAfee; I've been using McAfee since Windows XP and Thunderbird since before it "broke away" from Mozilla. They have, until 6 October, played nice together. I really like Thunderbird so I do not want to find another email client/program/what-have-you. There are LOTS of saved emails that I cannot move/copy to "save space", so...Help? Please?

Thanking you in advance, tonyg

P.S.-I am not computer illiterate. But, slow, easy to follow, non-BIOS changing, step by step directions would be preferred.

I am setting up a new email address on Thunderbird. I enter a new email address and when I enter password it is rejected. I have removed all previous emails and passwords

Hi,

I just cannot find any information on how Thunderbird designers see the Threads / Threading features to be used. How would I use it ? What are my (individual) choices for configuration ? etc.

The only info I can find is : [how to manage and turn on/off the feature].

...and of course lots unhappy user voices across the forums.

So: How would I use it ? What are my (individual) choices for configuration ? etc. Please link the respective Mozilla resource (blog, help, user design doc, ... whatever).

Ah, to start with, a description of how the feature is meant to behave, can be a start. (Sorry, I was just too stupid to find that)
