I'm grateful that I've been able to use Thunderbird for free up until now. I wouldn't mind making a small donation. However, Thunderbird's email service is currently unavailable. Received emails are not displayed in the inbox. All previous history has also been erased. First of all, I would like your cooperation in fixing the current problem and restoring the system to its previous state. I will make a donation as soon as the system is restored. If the system cannot be restored without a donation, you can make a donation first. I look forward to your reply.

Using TBird 115.10.1 64-bit on Windows 11. For ease of reading text in mail I am composing, I would like to select a large font size. In Settings | Fonts I chose Arial 18; but for some reason I get a small monospaced font whenever I start a new message. I can enlarge it with Ctrl-Plus, but it reverts to its old ways for the next new message. How can I make the change stick?

I have noticed in the help section that all sync data is removed if password is reset. I have just lost all my passwords, bookmarks, settings, everything, because I had to format my computer and didn't memorize my firefox password.

Is there any chance at all to have my data restored regardless? I understand I am at fault, but this outreach is my last hope, I guess.

I have a Yahoo email account and Firefox has the saved password for it. I've changed the password for my Yahoo email account recently. When Firefox prompted me if I want to update the saved password I must have chosen "NO", I don't remember. I stayed logged in the Yahoo email account for a few days after I've changed the password. I've logged out of the Yahoo account. Now I can't log back in because I don't remember the new password I've created.

I'm wondering if Firefox has the new Yahoo email account password saved somewhere in its cache.

OS: Windows 10. Firefox: 127.0.2 (64-bit).

I love Thunderbird and it has replaced Outlook (classic) for me, but there's one feature I miss, AutoArchive.

In Outlook (classic), emails older than x days can be automatically moved out of the server folders and into local folders, freeing up server storage space and negating the need to pay for additional cloud storage.

Thunderbird has the ability to select a group of messages in any folder and right-click > Archive (move) them to the matching Local Folder: perfect! But manually selecting multiple messages older than x days in multiple IMAP folders and selecting "Archive" is a chore too far.

Thunderbird should natively have the ability to (optionally) iterate across all IMAP folders and "Archive" any message older than x days, according to the Message Archives setting in Account Settings > Copies & Folders. The Disk Space setting in Account Settings could be an ideal place to add an "Archive messages more than x days old" option, since it already has a "Delete messages more than x days old" option.

Note: I know about the AutoarchiveReloaded add-on, but for something as important as shifting emails around with the possible breakage that could occur, and the possibility of the add-on being discontinued, native support would be very much welcome.

Another note: this has of course been raised on bugzilla,[1] but it's a 15 year old bug and seemingly unlikely to come to fruition.

"Unable to write the email to the mailbox. Make sure the fle system allows you write privileges, and you have enough disk space to copy the mailbox."

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

After updating Firefox, when searching on Google, it no longer recognizes my location. I'm in Minneapolis, but when I bring up maps, it shows Austin TX. I did try to update my default location on my computer, but it still keeps showing my location as Austin TX. Maps works fine on Microsoft Edge

I have over 35 email accounts, which I use Thunderbird to collect. Love Thunderbird for well over 2 decades!

I am wanting to have 2 of my email addresses to be downloaded before all the others. I have indeed successfully "moved" these 2 accounts to the top of my account list (Shift and mouse). However they are not downloaded in the order of the account list.

How do I accomplish this? Is it possible?

I created a ticket, and it auto-responded to run this by the Volunteer Community. I really want this to be handled by support, but welcome anyone to give me a solid answer.

This there a "Global" Message Filter Rule where you can change an Apply Filter When: to ALL your Message Filters?

Example: I'd like to add "Periodically, every 10 minutes" to ALL my current Message Filters. Currently, it looks like I have to Edit each and every one of them?

Thank you in advance.

When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

We had a storm and now email doesn't work. We are a business and have to have email. I've went in and changed the Mozilla password and when go back to email it won't accept it. Emails aren't coming through. Can't sign in. What do I do?

I get the pop up that includes Add Security Exception

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

I signed into the web browser and turned on Sync, and I did a new windows installation. When I re-downloaded firefox browser and signed in, I lost all my open tabs. Under connected services I can still see that my session from before I did the windows installation is still logged in, and I was wondering if there is any way I can retrieve my open tabs from that instance?

Thank you very much!
