In the last couple days, I am not receiving messages in my email account inbox (att.net/yahoo). Messages are going directly to the local inbox folder. Windows 10.

When I search for new emails in the local folder, they are tagged with a gold diamond, and my option is to "Move to inbox again," which does move the messages back to the main inbox. But, "again" implies that the message arrived in the account folder, but got automatically passed to local folder. On or two occasions, I noticed an very fast dowloading to the inbox, which disappears immediately.

And, I get no response in my email account when hitting F5. F5 works for the local folder, and other accounts, and Shift-F5 (getting messages for all accounts) updates the others, but not my main email account.

The issue is not with att.net/yahoo. I have checked all my settings and server settings in Thunderbird, done the folder repairs several times, closed and reopened Thunderbird many times, deleted Inbox.MSF, etc., but nothing works. The issue seems to be specific to Thunderbird. Any ideas?

I have Thunderbird configured to log in to 3 separate email accounts, one of which is a Yahoo email account. Several days ago, a message appeared that notified me that Thunderbird would not connect to the imap account in Yahoo. I tried changing the password by logging in to the Yahoo account via my browser, but Thunderbird still gives the error message. Do I need to delete the Yahoo account from Thunderbird and start over, or is there something else that can fix Thunderbird so I can use it for all 3 email accounts? Thank you.

I have no problem receiving emails on this account [redacted]@smartpointproducts.ca however sending or replying doesn't work it's not the passwords here's my SMTP server settings screenshot below.

About 4-6 weeks ago Chase started throwing an error message when I tried to log in. Some other banks, credit agencies, brokerage houses also same thing. The work with Chrome and Edge.

Can Mozilla get past this or do I give up and use a predatory browser?

Yesterday (10/1/26) Firefox went through SEVERAL updates to v.157.0. Now, it behaves extremely buggy and locks up if I try to open more than one window. It was never this pathetic! I want to revert back to the previous version. Yes, I am running Win10.

Also, now it will not even close properly. I have to go into program manager to kill all of the subprocesses that have spawned. I DON'T LIKE THIS VERSION AT ALL!!!!!

Bonjour, La langue FRENCH est cochée dans mes paramètres et pourtant à chaque ouverture de la boite mail, tout est en anglais ! Je veux uniquement la langue FRENCH.

Merci

So I'm helping sort out an individual who is very computer illiterate and I'm getting them to use Firefox.. but when it updates, the window that tells you what's new pops up... now this is helpful for most! but for this individual it really confuses them and they tend to call me about it every time... so I'm wondering if their is a way to disable the popup window, to make it less confusing for them without disabling the updates entirely?

I have no accounts, no old emails, nothing.

I have 2 PlusNet accounts & 1 Yahoo account, which I now use as my main email. The PlusNet email(s) are about to become defunct because I am opting out of it being sold to Greenby. I had both IMAP & POP3 PlusNet accounts on TB. I have managed to delete the IMAP account, but I'm not able to switch my default email to Yahoo (greyed out button) & I'm scared to delete the PlusNet POP3 (or confirm my Greenby opt out) until I've confirmed Yahoo as my default/only email account on TB. I'm not confident Yahoo will automatically become my default if I delete PlusNet POP3.

Please help I'm old & not very techie.

Hello. I posted my first "Idea" three years ago, and it's still awaiting review. So are every single "Idea" I've submitted, and so are my comments on other people's ideas. Whenever I try to post about this here, the post is automatically removed. I don't understand what is going on. I haven't done anything to get my account banned or flagged or anything. I haven't received any notifications about why the posts are removed. What is going on?????

I use Thunderbird, download on my PC computers (desktop and laptop) and on my iphone (using apple email set up - not Tbird app). I have noticed the folders are not synced on all three devices. Some are missing. Am I not doing something to sync them?

Firefox uses firefox icon instead of website icon. Can change it thru properties/change icon but every time i make a shortcut i have to change it if i want the right one.

I have a filter setup to forward certain emails to another account. It has been working fine for years. Suddenly today I am getting an error message about not being able to contact the smtp server. If I manually forward the email to that same address it goes fine.

These are some things I have explored:

   • It is happening whether I look at emails in Thunderbird or through Gmail on Google Chrome
   • Even if I clickndrag them from deleted to inbox they fall back into deleted.
   • I’ve tried gmail/settings/all settings/filters and there aren’t any
   • I’ve tried gmail/settings/all settings/forwarding and there aren’t any
   • If I access Gmail via Microsoft Edge, the emails stay in Inbox
   • I’ve looked at various things in Thunderbird and unticked something in ‘When New emails arrive’ because I thought that might work.  

It started happening about a week ago.
