Since I migrated from ESR Channel to Release channel, the main Archive folder doesn't include all the subfolders. Later, I can manually select which folders I want to include in the main folder. For example: I can select only 2025, 2024, and 2023 subfolders to be showed inside the main Archive folders. Now, I can't find this option, and the last messages I can see are from 2023.

Hi all, I used to run two Firefox instances on the same computer, each one using a different account (as I mentioned in the Subject), but I don't remember how I managed this, so now that I moved to a new computer I can't reproduce it! Thanks for helping, if anyone knows. Regards, Mike

I have made a backup of my Thunderbird profile using this method:

https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

If my computer crashes I can restore my messages and settings from this backup, or if I buy a new PC I can copy the data over from a backup made the same day.

The backup contains settings and local folders, but my concern is that the backup also contains the contents of my regular inbox at the time of copying.

The contents in my inbox changes over time, so naturally it will differ from the saved inbox contents in the backup.

So what happens when I paste an older backup into the Thunderbird folder? Will this data overwrite all the contents in my inbox and basically revert the inbox to an older state? Or will my inbox be crammed with doubles?

Since I use IMAP, any changes to the messages in Thunderbird will sync to the mail server, so I really don't want to do anything that deletes things or makes a mess on the mail server.

Of course, it can be good to have a copy of my messages if the mail server crashes, but if I only need to transfer data to a new PC or restore my data after a computer crash, I would rather just download the up-to-date inbox contents from the server. At the same time, it's important to me to make this backup since I want to be able to transfer my settings and local folders.

In this case, should I remove some files in the backed up profile folder before the transfer? If so, which files? The folder structure and content of the subfolders "Mail" and "ImapMail" aren't very intuitive, with various subfolders and multiple files named "Inbox" of various sizes.

Appreciating any clarifications on the matter and help to avoid conflicts between copied/backed up profiles and my current inbox.

I currently have 3 Comcast mail accounts I access from my home PC using Outlook 2016 configured for POP3. For each of the 3 Outlook accounts I designate a common PST file on my home PC. Thus when launching Outlook messages from all 3 accounts are downloaded from Comcast and stored in this one PST file. Can I configure Thunderbird to do the same?

I am trying to convert from Chrome to Firefox. Everything is going well with my main account, but on my school account, I can't receive emails from out of my school district. Is there any way that I can make an account without email verification?

Hi,

I've been trying to get to the bottom of an error message that keeps coming up on my client's computer. They first noticed the error (ss) about a couple of weeks ago and anything from then won't download (incoming), but I believe they are able to send emails. I can see that the messages are 'waiting' on the server at least and they can temporarily use Webmail.

I looked through the forums and any other info I could find and have checked or tried the following:

• If their Antivirus or Firewall are blocking access
• There is enough space on their system
• File permissions for the 'Thunderbird' folder
• Access details
• Downgrading to an earlier version of Thunderbird

Unfortunately the error is still coming up each time they try to get their messages.

They have been using Thunderbird for almost a year now with one minor issue in that time. And I'm a bit puzzled as to what to try next. Has something similar happened to anyone else? Any suggestions for what I can do or check next?

The email account is through their domain and hosting and they are using Windows 8 and Thunderbird version 102.15.1 (from version 115.18.0 - 32-bit).

Thanks

Set up POP account to download and archive gmail messages. Worked fine, downloaded years of email. Did some traveling and two weeks later, it will only download messages received while the program is active. For example from 2/28/25 till today, did not open program. Today it will only show messages I have received while it is open and none of the messages between 2/28 and today appear.

Also trying to archive message twice using a separate computer. Tried that today and none of the old messages will download and only shows messages that are received while the program is open.

As of yesterday my Thunderbird account vanished, screen asking to set up an account. I am too old to be an IT expert, and I need detailed step by step guidance how to restore that account, full of Inbox emails and folders/subfolders. If it matters (depending on requirements?), my address is @verizon.net - which is pop3 but I have no problem opening the same emails on different devices, as if it were imap (verizon taken over by aol). Pain in the neck, hope to get help.
