With the latest update 115.11.0 the existing profile was not identified and loaded. All existing configurations, mail and address book are not accessible. The likely problem is the installer program that uses IP address as a factor in finding the correct Thunderbird account. I use VPN and do not have a static IP address. I have been shut down for several days now and any attempt on my part to resolve the issue has failed. The old email is very significant. Unannounced updates can cause serious trauma for Thunderbird users.

I recently un-installed an old version of Thunderbird that was showing a vulnerabilty and would not patch itself to the latest version for some reason (old version was in the 60s). I had all mail stored in a non-standard folder on my D drive so that it would be included with my backups. After uninstalling, my non-standard folder is still there. However, the location where Thunderbird was originally installed was removed and that is not included in my backups.

I installed today the newest version of Thunderbird, but I cannot get it to open my old mail. I'm able to login to my accounts, but I need to access the email stored in my non-standard storage file.

I'm moving from win 10 to 11 in new PC. I downloaded Thunderbird. I have hidden files showing in new PC so I found where it should be. When I look for the Thunderbird I downloaded it's not there in roaming...so I can't move my profile into the new computer. I have it on a drive read to install, but it's not showing up.

i have 2 computers running the latest thunderbird 115.10.1 (64-bit) one is in perfect layout exactly the way i want it the other has more layout issues than i have time to fix to make it back the way i want ( a fresh install ) i just want to copy the lay out not the accounts , not anything else is there a file or 2 i can just copy and put on the new computer ? and make thunderbird look normal

I am replacing a ten yr. old Dell Desktop with a new HP Laptop. Can you please let me know how to get the new laptop working with my existing Firefox (v125.0.3) with current add-ons, extensions and settings? Thank you for your time !! Rick Perry

I access a Gmail account with Thunderbird from browsers on differing machines. I also tried using Thunderbird itself to access the mail in Gmail.

So we have three different pieces here: A) Gmail account itself B) Thunderbird's view of the gmail account C) Thunderbird's local folders

What I was expecting was:

1) Thunderbird would pull copies of info on gmail (A) to Thunderbird's view of gmail account (B).

2) I would drag and drop folders or emails into the local folders (C) from Thunderbird's view of gmail account (B)

3) I would end up with gmail itself (A) having the email, Thunderbirds view of gmail account (B), and a copy in local folders (C).

You'll ask "Was it IMAP or SMTP/POP?". I entered the info in TB for the IMAP. There is SMTP information too that I see in TB. However, on gmail's settings on gmail itself says IMAP is disabled. POP is not disabled.

What I've got is confusion and things not where I expected.

1) I had Thunderbird pull info to its version of the gmail. 2) I dragged and dropped things (folders and emails) into local folders thinking I was making copies

Instead of what I expected, I ended up with:

Gmail account (A): All the tags somehow got pulled and the email is all sitting (I think maybe) in 'All Mail'. Not sure as there are hundreds of emails to look at an I think some things have been taken out of gmail.

Thunderbird's version of gmail account (B): Had a lot of email from gmail that had identical folders under the account in TB. Now those folders under TB's version of the email from gmail are empty.

Thunderbird's local folders (C): I think all the missing email from both gmail (A) and Thunderbird's version of the gmail account B) are now in local folders.

That's very much not the outcome I was looking for. I also was unclear was whether folders under the gmail account in Thunderbird were (in fact) local... the presence of the 'local folders' separately left me unsure.

I haven't used a mail client for personal use for a decade or more now. I use webmail (gmail). However, I wanted to do what I would have done in the old days - I wanted to pull down a copy of everything in gmail and save it (back when, it would have been as a .PST).

Mostly I was hoping for: I) Gmail mail is left on gmail. II) TB's version of the gmail account holds a copy of everything in gmail III) and I can backup, with a structure similar to gmail being preserved, a local repository (in whatever the right export format is these days) IV) If I'm in Thunderbird, I can send an email via gmail

I believe I can get every email that was messed up on gmail back there with some work. What I don't know is how to do what I want to do , as described immediately above. (Items I, II, III, and IV)

How can I do those things?

And are the folders under the gmail account representation in Thunderbird actually local? If so, why is there also local folders?

My computer updated with no warning one night, and i lost all personalization and even everything stored in my firefox, the sign ins, passwords, bookmarks, all. is there a way for me to find all that was erased?

Hello, First post and could not find this surprisingly... I'm wondering what settings to use for windows 11 VPN section. i installed on my desktop but when i go to VPN settings in current win 11 it does not list a VPN. is this possible to use Mozilla VPN at OS level or is it only via ff browser?

 Thanks! 

I love Mozilla and what they do with their products! :-)

Had all my emails stored locally. Accidentally uninstalled Thunderbird. Reinstalled. Unable to Import my old settings from my "profile". Error message says "Unexpected error" Was able to import configuration alone, but it was all wrong. Can't set up my gmail account. Error message "Malformed server" Please help

I'm setting up Thunderbird for the 1st time with multiple email and calendar accounts.

One of the accounts, an O365 account, is not setting-up the sub-folders.

I was also having issues with the same account's calendar and have implemented Tbsync Account Manager from the add-in and that seems to have fixed it.

Now on to the folders issue. The only folders appearing are the Inbox and Trash.

Any suggestions?

Always shows "Failed to check for updates" On version 125.0.3 and still says needs to be updated. Then just run the install again and then it stops for a bit still on same version and then shows up needing update...been doing the same thing for a while now.

I know that there is a generic Linux iteration that can be downloaded, but it does not appear to allow for use on ARM64. Is there a way that I can download, install, and access Firefox on my Orange Pi 5 Plus?
