Continuation of my prior post: https://support.mozilla.org/en-US/questions/1516342

Thunderbird has a routine problem with being unable to log into various mail servers. I have four accounts and they all seem to share this problem.

Most recent update: I've tested this in Windows Safe Mode, and the problem has not appeared. Since I can't do any useful work in Safe Mode, it's hard to give it a thorough test, but so far so good. Also, I have removed AVG antivirus because it was redundant. I have seen no improvement since it was removed.

Can this problem be resolved?

Hello all:

Transferring Thunderbird from the system above to the system noted above. Follow the instructions from here on the Mozilla Support page (copied both "Thunderbird" directories into the Roaming and Local destination directories. When the destination machine installation opens, it is functional (i.e. it picks up all the existing e-mail accounts, downloads new mail, etc...). The problem starts when we get to the local folders.

All of these have a date and time appended to them in the destination installation. For example, if the original folder is "Prosperity Bank" the destination folder is labeled "Prosperity Bank (2025_09_21 23_06_33 UTC)" and will not let not populate (shows no messages inside).

As I am typing this, it seems I may have identified the problem (or at least part of it). It seems the destination system install is slowly working its way through the local folders randomly (not in alphabetically order), as it seems to be slowly populating them with the old mail stored therein on the original system. It is going very slowly. Very slowly.

Has anyone else experienced this? Is it normal? Is there any way to quickly eliminate the dates now appended to the local file names? (Visually this is very annoying and I do not want to try modifying the individual folder names yet until I'm sure its populated as much as it will populate.)

Thank you for any assistance.

Please Please Please advise how to modify settings to stop copying emails to "All Mail" folder. There are nearly 14K emails in that folder, and it's killing my capacity, I'm getting warnings, etc. Yes, I'm using Gmail.

Yes, I have unsubcribed from it, starting from my account name → Subscribe → unchecked [Gmail] All Mail. To no avail...

Of course, I do not want to delete mails I have saved in my hundreds of other folders. My mail goes back 25+ years, and I want to keep those archives.

Thank you Thank you Thank you!

I'm on Win10. This morning I see that MSLOP has updated my desktop PC overnight. FF was open before the update and attempted to restart but couldn't restore pages. I told it to start a new session and the PC blue screened. This has happened before so after the PC restarted I shut it down. It blue screened a few times while also trying to restart FF. I shut it down with the power button. FF will not start with troubleshooting (shift while double clicking on FF icon). It crashes and I get the crash window. Latest crash detail is below. What next? Any help is much appreciated.

UPDATE: I went to windows settings, apps, and clicked on uninstall for FF. Immediately a message box, "Would you like to refresh instead?" popped up. Sure, why not? It thought for a while and updated. I logged in again and I am back to a functioning 147.0.3. I logged into my bitwarden extension and ublock origin is still there. No clue what happened earlier.

Windows 10 became unavailable, but I have a copy of the drive it was on. I had tried to install Linux Mint as dual boot and couldn't get to Windows any more. Installed Linux Mint 22 on that drive, wiping out everything that was on it. Now I really want to get all of my locally saved items from the copy of the old drive onto TB in LM22. The profile folders are there, I just don't know what to do with them. FYI, all of my other data files were on other hard drives, so only the OS and apps were on the boot drive.

Thunderbird 147.0.1 dropping all local email and redownloading

I am running Thunderbird 147.0.1 (64-bit) on Windows 11 Pro 25H2. I have Thunderbird set up with two email accounts -- gmail and outlook.com (an old msn.com address). Approximately every 10-14 days the msn.com account encounters an error with the message "Command Error 12." When this happens, Thunderbird immediately drops all the local email folders for the msn.com account, and attempts to redownload all email and folders associated with the account. The msn.com account in question is configured for IMAP:

server name: outlook.office365.com Port:993 Connection Security: SSL/TLS Authentication Method: OAuth2

The expected behavior here would be for Thunderbird to display a connectivity error message but retain all local email on my laptop. However, this specific connectivity issue is dropping all locally stored email. I also noticed that the mail columns get reset to default. It appears this issue is causing Thunderbird to delete not just the email but some of the account configs as well.

At present, I do not have a screenshot showing the command error 12 message. I will try to take a screenshot the next time the issue occurs. What is not clear is whether this is an account setup issue or a bug in Thunderbird. Any advice would be appreciated. Thanks.

I recently got a new laptop with Windows 11 Pro. I installed Firefox from the Mozilla site. When I click to open Firefox, it takes a long time - 41 seconds to be exact. I uninstalled, reinstalled and restarted my computer. I cleared the cache. I tried to run as administrator. Not sure what else to try. As I wait for it to open, it reads "not responding" in the search bar area. Any ideas?

Folder name: BOGUS AI PRAISE-MKTING-BOOK CLUB BULLSHIT I had been adding emailed marketing messages that I knew were fake into this folder for about two weeks. This morning, after a Windows 11 Update, when I tried to add another such message to that folder, the entire file folder was missing. I tried everything I could think of, including looking for help online, to no avail. This folder contained around 500 emails, over 200 of which I hadn't even opened.

I'm trying to find the proper way to revert back to the default location for local mail message storage in TB (ver 140.7.1 esr).

Years ago I set my local message storage to a storage drive on my Win10 PC. I now want to move all of TB to a new Win11 PC but realize I have thing in 2 places - messages on my storage drive and everything else of TB in the default C: drive location.

If I simply change the Message Storage Local Directory back to the default path - will it move my current/old messages to the default location or do I have to manually move things (first or after?)?

I have many years and about 13Gb of email messages that I want to ensure I keep.

TIA

I use Firefox for genealogy research because it always keeps track of which pages I've previously accessed since their hyperlink will change color. Today, I ran Microsoft's PC Manager software and it suggested clearing the cache of Chrome and Edge. For some reason it also must have cleared the cache of Firefox since the previously accessed hyperlinks are no longer a different color. Since I had a created a restore point this morning before installing PC Manager, I restored the system to that point. Following the restore, Firefox would not open so I re-installed it from the website. I had previously backed up the profile folder and so copied that to the new profile folder of the fresh install. My bookmarks and history seem to be fine but I still don't see a color difference in the previously accessed hyperlinks. Any suggestions on how to get them back would be greatly appreciated.
