When I go through my email list, I delete the currently highlighted (selected) email by using the delete button or clicking on the delete button above the email message.

As I do this, every few messages, instead of just the selected email being deleted, another email higher up the list (newer in the list) also gets deleted.

I have noticed this with a recent update of Thunderbird in the last month or two.

Hi: I have had my Thunderbird on my computer for many years to receive and read my email on. Now in the past about two days or so every time I try to download my email from Xfinity Thundebird pops up and tells me the password is not being accepted. The only way I can get my email now is to sign on to Xfinity and use their website. Why I do not like this is I have my addresses and other important things on my Thunderbird website. I even got a computer tech to my house and he could not help me. PLEASE any suggestions?

I have 4 email address/accounts setup in Thunderbird (V 115.3.0) that accesses email through my Spectrum/Charter carrier. I am running Win 10 with all latest updates on a desktop PC, AVG free AV, and Defender firewall.

After the last 2 Thunderbird updates, my outgoing mail has began to fail. It was working fine before the updates. I have checked all settings in TB and have found that all of the SMTP settings are entered correctly, except some settings keep changing automatically.

The problem has been traced to the Account Settings/Edit SMTP Server where the last line for User Name is NOT stable for all four accounts. When the Account Settings User Name in the SMTP Server setting matches the account User Name in the Server Settings menu, outgoing mail works fine. However, when I try to use one of the other email accounts to send an outgoing email, I then get the error message below:

“Sending of the message failed. An error occurred while sending mail. The mail server responded: <warrenp3@charter.net> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again.”

I find that the User Name in the new 2nd email account now matches the User Name from the first email account. Now the 2nd outgoing email won’t work until I change the 2nd account’s User Name to match the 2nd email’s account. Unfortunately, changing the 2nd email setting with it’s own User Name then also changes the first email’s User Name to the 2nd one so that it now will get the above error message. I now have to back and forth like that in order to send emails from different accounts. No email account saves the User Name for it’s account nor do the passwords get saved for each account.

So help me resolve this issue. What can I do to correct these errors and get back to a usable email Thunderbird usage? HELP

I love Firefox. Haven't used ANYTHING else for years

Android 10

I don't use Facebook. When I click on a company's Facebook search result to open in Firefox... It tries to open in another app that can't open it, like a maps app or something like that.

Firefox is set as my choice as browser to open links with.

To be clear, when I click on the search result to open it, I am only given two choices that I can't use and don't want. This seems to only happen with Facebook. It doesn't give Facebook as a choice, which I don't use anyway

Thank you Dr Mark

I have had a few folders for years now that I can not seem to delete from my Thunderbird email system on my local computer. Anyone else have that issue? The folders all have similar names, but different. I can't even rename them to try deleting with new names.

I have an imap server (provider is LaPoste...) whose system folders are under INBOX/ (OUTBOX, JUNK, DRAFT, QUARANTAINE) instead of being at the root.

I have multiple TB clients, but the main one stores every sent mail in a local "Sent" folder while other mobile clients (other TB or smartphone native) leave them online in the default system places INBOX/OUTBOX. On the main TB client, I have configured unified folders to look for imap's INBOX/OUTBOX and the local "Sent" folders.

As expected, the "Sent" unified folder has a "Local Folder" subfolder which point to the local "Sent" folder but there is no other subfolder for that "LaPoste" account. Still, all INBOX/OUTBOX messages are directly under the root of the "Sent" unified folder.

Then this is where it becomes very confusing: what is being displayed under the unified "Inbox" and the folder for that LaPoste account changes kind of randomly after a TB restarts and during its's runtime., with 2 main cases:

1- The unified "InBox/LaPoste" folder shows OUTBOX, DRAFT, QUARANTAINE subfolders. They are populated with what's expected there but in that case, the "LaPoste" folder in the unified view is missing. I confirm that in the unified InBox properties, OUTBOX, DRAFT and QUARANTAINE of LaPoste are **not** checked

2- The unified "InBox/LaPoste" folder has no subfolder and in that case there is a "LaPoste" root folder in unified view with underneath OUTBOX, DRAFT, QUARANTAINE.

3- The unified "InBox" folder has no subfolder "LaPoste" but the messages from that account are still visible in unified "InBox". Then there is in unified view a "LaPoste" subfolder that will contain "OUTBOX", but not "INBOX"

I have **never** seen a "LaPoste" subfolder under the unified "Sent" folder.

If I use any other provider (say outlook) with a root folder structure that has a "Sent" folder and I do exactly as above, then this works as expected:

- Under the unified "Sent" there is an "<outlook_account>" folder where I can see the messages still in the imap boxes. There is also still the "Local Folder" subfolder that points to the local "Sent" folder where I can see messages sent from the main client. - The unified view for "<outlook_account>" displays all remaining folders that have not been "allocated" to a unified folder for that account.

NB: I had opened another question that was around the same topic but with a poor description, so I closed it, sorry about that.

After updating to the newest version, I am seeing an issue when I create a new Event. When I add an attendee, instead of the single attendee record intended, there are 3 additional attendee rows, 2 blanks a duplicate to the one I added.

Thanks, Dave

Every time Firefox updates, a Firefox shortcut is added to my desktop. In delete it because I already have a shortcut for it in the taskbar. How can I stop this from happening? I have tried turning off automatic updates and manually updating the browser and it still creates a shortcut. It's been happening for over a year and I am close to uninstalling Firefox completely and switching browsers.

Thunderbird appears to be installed and working correctly. I'd like to backup my profile and be able to repair it if needed. I installed Thunderbird 115.2.3 through the Windows App store. I believe that the program is actually installed at C:\Program Files\WindowsApps, which I cannot access even with elevated authority without disabling permissions I don't understand. I am reluctant to do this.

The Help > Troubleshooting Information page shows a < Open Folder > for my profile, but when I click it it says that C:/users/xxxxxxxx/Appdata/Roaming/Thunderbird/... doesn't exist. The File Explorer shows there is no C:\users\...\Thunderbird folder. How should I proceed?

Additional information:

I discovered this because I wanted to make a shortcut to put in my Startup folder (C:\Users\xxxxxx\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup) and couldn't find the program anywhere. There are 2 executable files ("*.exe") with a size of 0 bytes that I was able to find use to create a shortcut at: C:\Users\xxxxxxx\AppData\Local\Microsoft\WindowsApps C:\Users\xxxxxxx\AppData\Local\Microsoft\WindowsApps\MozillaThunderbird.xxxxxxxx It should be easy to create a shortcut for an executable.

Starting thunderbird at a command prompt to show the profiles says there are 2 profiles labelled < default-release > and <default >. default-release is highlighted.

Several attributes disappeared with latest updates introducing supernova. I've found the CSS code #toolbar-menubar{order:-1 !important;} added to userChrome.css works to move the Menu bar to the top. I've tried several examples of CSS code to set tree rows eg Inbox to display alternate rows background white/grey, however, none seem to work. Any suggestions? Thank-you.

Thunderbird: Folder with 119 message, need to send all 119 messages to an e-mail from Local box called "Fraudfiles". I can not see any way to do this in Thunderbird e-mail.

I have screenshots of the error I receive when logged into the website. The support staff from LawofSelfDefense.com says everything on their side says I should be receiving audio and video. I have checked DuckDuckGo privacy settings and they indicate that their product is not blocking anything from the website.

I used MS Edge this morning to stream a live episode and it works! I do not want to access these streams using any MS products/software. Something in Firefox is preventing me from Live video and Chat activity on the site. What can I send you to help me fix this problem?

Hi Yesterday I installed the new thunderbird 115 version.

now I cannot see e mail content when &i click on the massage. It is there if I select from a drop down. how can I return to the original format.?

Also having trouble logging in,

I want to do a new set up for my main e mail address. the configuration is found in the system but I cannot log in 
I have tried every e mail I have written down none are working, how can I set up a new password?

I have telus email which is not configured through google the set up is inbound imap.gmail.com 993 outbound SMTP SSL/TLS

System:

Windows 10 pro 22h2 19045.3516

Intel i5-10200h with UHD 620

Driver 31.0.101.2125

Firefox ESR 115.3.0

When watching streams in firefox, I noticed that overall iGPU load is very high, up to 70%, a lot higher than watching 1080p movie with dedicated player.

I found that the firefox actually only shares 10~20 iGPU load, the rest are from DWM, which load is up to 40% sometimes.

Also found if I switch from the tab with streaming page to another normal webpage, DWM immediately drops its usage to about 2%, firefox still uses some load as it's still decoding. DWM usage rises if I switch back.

I tried force firefox to use nvidia dGPU, firefox does use nvidia card to decode, but the DWM problem said above still apply.

See attatched image as prove.

After a crash and new Firefox update today (September 28, 2023), Firefox is now opening a new window along with every new tab. If I close the newly opened window, the tab on the browser 'main' firefox window also closes. The 'open links instead of new windows' is ticked. I have tried refreshing Firefox and also uninstalling and reinstalling. Running on Windows 10. Please help! Thanks, Robin

I am trying to re-establish one of my email accounts in Thunderbird using a new OS (fresh install for both OS and Thunderbird). Auto settings work just fine until it gets to verifying my password where it fails. This is a password that was used for a previous account in Thunderbird on my previous OS where it worked without issue. I can go to my provider and log in using this password without issue. I have not yet tried changing the password as I can't rationalize why that should matter. Actually, I logged onto this site using that password. So, I know it works.

I'm using Thunderbird to access Microsoft 365 Exchange. I have Online Archive activated on my Exchange account. Is there a way to configure Thunderbird to see the Microsoft Online Archive?
