I hope I sent this to the right place.

PC is using Windows 11, latest updates. I have signed in to Mozilla Monitor many times in the last hour, but "Upgrade to Premium" does not appear in the upper-right corner as several help websites say it should. I cleared all cookies and turned Enhanced Tracking Protection off for the site, no help. I restarted Firefox - it's now at release 145.0.1 (64-bit), no help. Any other ideas? Thanx.

I have an email account with BlueHost, which also hosts my web domain. A couple weeks ago I stopped receiving emails and contacted BlueHost tech support. The agent had no clue why I wasn't receiving email. She said "Can you please click on acocunt actions and remove the account and re-addd it. [sic]" I did that, and I was again able to receive emails. But then all my old emails -- sent and received -- had disappeared. BlueHost was able to restore my Inbox emails back to May 19, but was not able to recover any Sent emails. I have a backup of my Thunderbird directory from April, but would like to recover all of my old emails, which apparently still exist because my current Thunderbird Profiles directory contains files corresponding to deleted email folders. For example, my Inbox had a subfolder -- call it ABC -- that was deleted and is no longer visible in my Inbox, but I can find files ABC (no extension) and ABC.msf in my Inbox.sbd folder. My Sent.sbd folder also contains files ABC and ABC.msf. These folders are in C:\Users\aaa\AppData\Roaming\Thunderbird\Profiles\aaa.default\Mail\mail.aaa.com (with "aaa" representing my personal identifiers). mail.aaa.com contains files Inbox, Inbox.msf, Sent, and Sent.msf, which seem to contain my old emails. (Inbox is 132,151 KB and Sent is 289,829 KB, and the file dates are from a couple weeks ago, when I removed and re-added the email account.)

Is there a way that I can recover the old emails?

Email problem. Old Lenovo Desktop, Window 8.0 (I know, I know, but it's my wife's and all she uses it for is email and utube recipes, and she's used to it). I use it for some banking, mainly because the printer is on it. Tbird 115.18.0 (32 bit) -says it's up to date AVG antivirus free

Email through yahoo. It worked fine until, going by the last date it linked email, 10/30/25 at 06:45AM MST When I tried to download new messages Sunday 11/2, it failed.

It pops up a new window "Enter credentials for bababarb@yahoo.com on imap.mail.yahoo.com" In the address window is "https://login.yahoo.com/?src=thunderbird&client_id=(about a zillion characters) Then, in the message window is "Edge: Too many requests"

So, I did the troubleshooting as in Help article. I logged in on the webmail, signed in with the password, and was able to see the messages, many from after the 30th (she gets a ton of sorta spam).

Looking under Account setting> server settings, I find that the security is set to SSL/TLS and Authentication is set to OAuth2. Incidentally, these were set automatically when I set this to a yahoo.com address.

So, I try setting the Authentication to Password and request mail. I get a popup asking for the password. I enter it (the same password I used on webmail) and it replies "Login to server imap.mail.yahoo.com with username bababarb@yahoo.com failed."

Following suggestions on the help article, I got to Settings, and check "saved passwords". Then, again following the suggestions, I remove the yahoo password entry. According to the article, the next login attempt should ask for a password. It does not. I just get the "too many requests" popup. What the hell, I go back and remove the SMTP password, too. Same result.

Anybody else having this issue? Any suggestions?

Hello,

I have to add the Password every time I open Thunderbird because I removed the Password myself after I read this:

<<<< ThundaMike Mozilla Staff 7/28/25, 9:15 PM more options Sounds like you are almost there.

Building off what @david said above, try this:

In Thunderbird, go to Settings > Privacy & Security.

Scroll down to the Passwords section and click Saved Passwords….

Find your email account in the list and remove the saved password.

Restart Thunderbird.

When prompted, enter your new password. >>>

My doing this it removed the .twc password Log In totally in that Settings. I do not see the "my twc.com" in the settings of Tools, Privacy & Security, then Saved Passwords in the list, I only see the Hotmail account settings I have in Thunderbird. Removing it like ThundaMike wrote really removed all the TWC Password and Information.

Can someone help me restoring or re-enter my Mozilla Thunderbird info back into Tools, Privacy & Security, then Saved Passwords so I do not have to type in the Password every time I open Thunderbird.

Thank you so much for your time and efforts I truly appreciate it.

Just installed TB for Android on Samsung S24 Fe. Works fine but am unable to exit the application other than forcing phone back to home screen. Have installed on a Samsung tablet and the back button seems to be working OK. Anyone know of any issues with this phone and TB?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

Until last month, Thunderbird never had any issue connecting to GMAIL accounts to send and receive messages. Suddenly, there is a bug and Thunderbird is not sending or receiving emails from GMAIL. Is anyone else experiencing this? Also, with the current version of Thunderbird, there is no way to insure that I am receiving updates and have the most current version. I have used Thunderbird for decades and it is now very buggy, and getting more difficult to use! - Mark Robbins

Been using thunderbird for years, stopped getting new messages. Removed/deleted the accounts and tried to setup again and get error unable to login at server, probably wrong configuration, username or password. username and password are entered correctly, changed them just to verify, using default settings and appear to match what their supposed to be as documented. Gmail accounts... Any help appreciated...

Today as I got to work (Windows 11 machine), I had a suspicious Firefox.exe file on my Desktop, it was not a shortcut, but exe file. I did a little investigation and research, and I noticed some difference from Program Files exe file and Firefox.exe on my Desktop:

C:\Program Files\Mozilla Firefox\firefox.exe

Size: 695424 bytes SHA-256 hash: EEB242895F8ED48B43EAAA9ECA06C6DDE54425F8AE0E16200D2D46F839B9A540 File version: 145.0.0.327 Copyright: ©Firefox and Mozilla Developers Date modified: 16.11.2025 12:35 Original filename: firefox.exe Digital Signature: Mozilla Corporation

and Firefox.exe that appeared on Desktop

C:\Users\User\Desktop\Firefox.exe

Size: 389248 bytes SHA-256 hash: E8DA5735FE1B5E92BA3636B8D17B5BEC0EA521DB6A8B5A52177FF3E8B2F60710 File version: 145.0.0.327 Copyright: Licence: MPL 2 Date modified: 16.11.2025 12:35 Original filename: desktop-launcher.exe Digital Signature: Mozilla Corporation

I scanned both files in VirusTotal, and they both seems clean and legit

I uploaded both files to:

https://drive.google.com/file/d/1kALgQbfhIpHqs1pN6dmTdF71nm10LlD-/view?usp=sharing

Can somebody assure me that both files are OK, and can somebody explain to me why Firefox.exe appeared on my Desktop, and why is there difference between two files in size, Copyright info, and original filename ?

I can't send Free-online emails on Thunderbird/Macbook, although I can receive them (see Error notification attached). I checked the Outgoing server settings in the Accounts settings which seem right (relay.free-online.net). This has been happening for about a week. Thanks for your help.

Firefox updated automatically. No bookmarks or history??? I cannot find anything. This is my old Windows 10 computer. Have bookmarks on Windows 11 computer. Afraid of updates. any help?

AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

I just installed Thunderbird 12.0 on my Phone (Galaxy Note20, Android 13). Account setting were taken from my Desktop PC using the QR Code. In all three Accounts only Mails in the Main IMAP-Inbox are shown. Subfolders (like "sent" or "drafts") are all found, but the messages inside will not be shown. It will only say "Load more messages" but does not find any. In K9-Maiil 11.1 this still worked, but I had to uninstall it as after the automatic update to 12.0 it suddenly kept crashing on startup.

Already tried to add my main account from scratch on my tablet (with a fresh install of Thunderbird 12.0), but the problem with empty subfolders remains.

Any thoughts on this?

Spectrum had me change my password for one of my accounts on Thunderbird. I changed it with Spectrum. That account was working fine from Nov. 6 until today, Nov. 16; today, it decided that my password wouldn't work. I tried to change it when it asked at the time I was trying to send an email; it wouldn't take. I then went into "saved passwords" and tried to change it; it wanted a pin. This is my** first problem;** Norton has no idea what that is. Thunderbird asked for other sign-in methods including a Yahoo email, but I have no idea what it wants as it doesn't want the password for that Yahoo account. What is it looking for????

I deleted the account from Thunderbird's password manager. After my shutting down and reopening Thunderbird a few times, it finally worked --however, it didn't ask for a password and sent and received email just fine. Thunderbird now doesn't have that account listed in its password manager, but is giving me my mail and sending my mail out without asking me for a password. **This is my second problem.**

Since this is all combined, I'm sending both questions together; otherwise, I wouldn't do so. Does anyone know what's happening and how to get a password back as a necessity for that email account?
