Hi,

In my one account in Thunderbird, I still have the old POP folders, that was a different account. I also have an IMAP account, both have the same address. The pop one does not work but the folders are there, I use them to look old mails up, so far so good. When I sent out an email with my IMAP account, the sent mail goes into the sent folder of the IMAP account, so far so good. BUT when I click on that sent mail and click on reply, it replies to the same address that what it already was sent to, now here comes the problem. THAT copy of the mail, I called the NEW sent, does not go into my sent folder. It goes directly into the sent folder of my old pop account. Even though everything on the IMAP account is standard, re-sent mails are not placed in the IMAP account sent folder. What am I doing wrong here, I know when writing the mail is that I can choose the send address and if I change that it goes in the IMAP sent folder but why is it standard on my old POP account, and why not on the IMAP account even though the IMAP is the standard?

For years I had an pop account in my Thunderbird, next to my Imap account. Both live happily next to each other. Today I moved all the mails from my pop account (which was no long active, nor was it connected to a server) to my local folders. I found out that all of my folder were suddenly twice the size. Compressing didn't do a thing. Why is this?

I type enter and there is an extra blank line

Like this

I can't seem to find a way to stop it.

It doesn't affect bullet lists:

• Bulleted list item
• Bulleted list item

But I can't provide a tidy chunk of information, e.g. when providing my Address to someone (where bulleting doesn't make sense)

Probably something obvious - I tried from 'Format' menu changing from 'Paragraph' to 'Body Text' but it doesn't seem to stick.

FOUND IT: From MAIN APPLICATION window Menu...Edit...Settings...UNCHECK 'Use Paragraph format instead of Body Text by default' I must have checked it at some stage (or maybe it's the default)

Sometimes I enjoy a conversation with myself...but in any case maybe someone else could find this useful.

Situation: Several Earthlink accounts using IMAP in Thunderbird. Earthlink/mindspring folders show the same folders as webmail. However, Thunderbird includes (by default?) "Sent Spam" and "Virus Blocker" folders. These are not visible in Earthlink webmail.

The folder subscribe function doesn't appear to do anything.

Deleting the msf files from the profile and restarting Thunderbird recreates the MSF files, and the empty, non-existent (on webmail) folders persist.

Have had this issue for a very long time. Would like to know, just to assuage a tiny bit of OCD, how to remove the folders from the list displayed for the account(s) on Thunderbird.

Thanks in advance. M

I Am needing some help. I was using Proton VPN (free version to try it out) and it was working fine until just now when I opened my thunderbird and it keeps saying pop.dreamhost has been reset and I cannot get my emails now. I looked at the help section here and it said something on here about issues with this and so I tried the suggestions there and it did not work so I just disconnected the VPN entirely and restarted my laptop and it still is giving me the same issues. I need step by step on how to be able to get my emails working again on thunderbird here and also what to do step by step so if I use a VPN again that this will not happen as I travel and need to have access to my emails without these issues. I Am not very technical so an easy step by step would be appreciated. Please help. Thank you

Unsure cause as not happening when using Brave. When right click on any site using Mozilla suddenly, the black writing must be white on white background as link still works but cannot read. What gives? Attached one example.

The problem of hanging on specific web pages but not always in the same place greatly increased 11/22/2026 running Firefox 115.38ESR under Windows 7 so I suspect that it is due to some widespread update and a new esr update is needed. 115.43.1esr did not help. Sometimes it happens while loading a page, sometimes when attempting to scroll the page and sometimes when entering data into a field.

Sometimes when viewing a page it skips to the bottom of the page. I try to use the slide on the right to control it but it ignors my mouse and drops to the page bottom. I try to restart the system and it does not help. Once it starts this dropping phase. I have to close the laptop and go about another task. This is most ignoring.

Из-за нового обновления «Nova» на вкладке приватного просмотра в Firefox появился этот значок; он смещает вкладки вниз, оставляя пустое пространство между вкладкой и верхним краем экрана. / Due to the new "Nova" update, this icon has appeared in Firefox's private browsing tab; it shifts my tabs down from the very top, leaving an empty space between the tab and the top edge of the screen.

Example why question is being asked:

Three separate GMX email accounts, each with its own unique password, and NOW Application-specific password for Thunderbird. Aliases are not used or desired. Three different separate accounts that should each have its own outgoing server.

Worked fine until updates to Thunderbird and changes to the GMX server, and Application-specific passwords became a requirement to send and receive email.

Seems like updates to nearly every program and/or app that may be released with the intent to resolve an issue or include a new feature breaks something else. M$ is horrible with updates and labels nearly everything as a critical update so it gets pushed through even when updates are turned off or supposedly permanently disabled by a registry hack; Windows 11 being the absolute worse ever. Why I only have one computer with M$ while all the others are Linux. Problems all the time with M$ while Linux simply continues to work.

Regardless, can setup each GMX account but the default email account name must be used as the user name on the other two GMX accounts on the outgoing server in order to send email. Then the recipient sees the name for the default account rather than the name assigned to the other two accounts, and the Application-specific password for Thunderbird must be changed to that of the default. Then attempting to pull down email for the other two pop accounts comes to a halt, and email messages can only be viewed by going to the online account.

Two separate accounts for yahoo, two for gmail, and one for Charter work fine, each has its own name and outgoing server. Should be the same way for GMX but is not because Thunderbird requires one of the three GMX accounts is set to Default.

Appears by having a Default email account, users are not only restricted by the default account, but email that is sent is done so with he incorrect name, The purpose for three different emails is for email segregation and better management; personal correspondence, business related, and Internet stuff.

Instead of having a 'Default' email account, makes more sense to use a valid email to register Thunderbird after downloading and installing, and then using that email for Support, Boards, assistance, etc. The default email requirement causes too many frustrating unneeded issues that should not occur, along with wasted time, stress and grief. Computers were suppose to make our lives easier and allow us more time for the real world. Biggest lie told since the Bell Labs created the transistor.

i need this site for visa application

the message is Seien Sie vorsichtig. Irgendetwas stimmt hier nicht.

Firefox hat ein möglicherweise schwerwiegendes Sicherheitsproblem auf indianvisaonline.gov.in entdeckt. Jemand, der sich als die Website ausgibt, könnte versuchen, Dinge wie Kreditkartendaten, Passwörter oder E-Mails zu stehlen.

When Firefox is opened, it reduces the size of the screen! I don't like this and probably selected this without knowing what it was doing. I want to go back to the original full screen! How can I make this happen?

After a 10/20/26 update I cannot sign into my credit union through Firefox. I can sign in using Flex and other search engines. Why???

After a lot of research, I thought I had the filter issue conquered. I perhaps made them too complicated, using several "match any of the following" by using the plus sign and entering into the second window which appears. I used "match any of the following" For "from" I chose "from, subject, cc".

After creating a zillion of them, I wanted to edit one or more and when I click "edit" I get:

"This filter was probably created by a newer or incompatible version of Thunderbird. You cannot enable this filter because we don’t know how to apply it." Using 151.0 (64-bit) Thanks....

Since the latest changes of Ff, I keep getting more and more websites, where instead of becoming connected, I get "Something does not seem to look right..." How do I override this? I have not asked for such help from a browser. These are sites, some of which I have visited for years. This is the question: How do I stop this and override this? I am not asking for an explanation why you feel you need to save me, I simply want to see if there is a way to override this.
