I used to have several mailing lists, and now I can't find them. They used to be an option on the Window tab, but now I can't find them anywhere. An existing one still works if I send to it, but I can't find it to edit (add/remove members). I'm 115.6.1 on MacBook Pro Sonoma 14.2.1 (23C71). Thanks.

Hi, Windows 11, 32GB memory. Firefox crashes regularly when between 1.6 and 1.9 GB is consumed It happens when watching YouTube. What is the solution, please? Thank you.

My email is driving me mad! I can receive emails no problem, but can I send them?? No. It just keeps timing out. Very annoying, I've been through every possible support forum and tried everything, I've increased the timeout time, I've checked the SMTP is all right, it is, I've deleted my account and the programme itself and reinstalled all to no avail. Very frustrating. Any help would be greatly appreciated!

short version: using: Thunderbird 38.3.0 mail is : sympatico isp: bell Windows7 64 bit

can't send email no matter how I change settings - I have done every imaginable configuration, filling in fields differently - I have done all that Mozilla suggests - firewall/virus on and off - new passwords - contacted isp which made things worse as they "don't support thunderbird" - I have uninstalled, reinstalled, tried to revert to old Thunderbird (but was too dumb to figure that one out), switched ports, gone through mozilla support and knowledge base - half the problem is I don't understand what it's asking me to do. It has taken me days just to figure out how to 'sign up' for help - I could only see the sign in area and just finally now, after days, managed to set up my mozilla account. After a week of this and about 30 hours in, I have been willing to pay tech support, only to find out that Thunderbird has no third party tech or phone support - my ISP however, who will not assist, said they can help if I subscribe to a third party service for a monthly fee. For obvious reasons, I'd rather not. I have added my screen shot of the current settings - but believe me, I've switched them all around many times. Thank you in advance for any advice, and apologies in advance for my ignorance in figuring out something that is quite likely simple.

long version: I use thunderbird because it's closest to Outlook which I was used to, but didn't come on Windows7. A week ago my boss required we have a Gmail account. I already have two that I set up just to take the names, both of which I added into my thunderbird no problem so I could see them without going online. This new one I set up is for work only - I added it to Thunderbird like I did the others ( I think) and all of a sudden my sympatico account was gone - I didn't even realize except that when I checked email on my ipad, there was no mail and I finally figured out everything I sent off my desktop was going through this new gmail account and my normal sympatico email was gone. I deleted the gmail from my Thunderbird and tried to put sympatico profile back on - days doing this - it was at the bottom - couldn't get it to the default, etc... Finally got it back and then couldn't send or receive - called my ISP - got new passwords - could receive but not send - isp Tech said it was their end. 24 hours later it worked - but only for the night - spent two more days with three techs and they all said it was how Thunderbird was set up and not their problem. I have gone through all the knowledge bases I can wrap my head around, called isp again today to ask if they're blocking my port (which the Mozilla help said to do)- of course they said no and laughed at me. I fear they have done something so I can't send email. They kept telling my I shouldn't be using Thunderbird.

I would be so grateful if someone could help me and understand my limited knowledge. Although, the information I've gleaned over the past week is immense!

Thank you in advance - and know that I really did look at so many other forums and help areas - it's just all a blur.

Hi there, I am getting terribly frustrated, desperately appreciate some help!

For over a week now, I can receive emails just fine, but sending fails completely. It has been working for years, but all of a sudden stopped.

Errors include (see images attached).

Have tried numerous SMTP settings and servers.

Using: Mozilla Thunderbird 52.2.1 (and later version, but rolled back to see if problem got fixed.) Windows7 Pro Avast Antivirus BT Fibre to Home

Any help be greatly appreciated. cheers, Chris

P.S. NOTE: One thing to bear in mind, this did occur at similar time of trying the BETA version on the Outlook Mail Website (But that was on a different PC). Maybe a coincidence, but thought I would mention it anyhow.

Additions: I have tried: • disabling my Antivirus. • rolling back Thunderbird several times to previous versions. • testing port allowance through router.

UPDATE - I have just installed the Outlook App on my android phone, set up my POP account, and IT WORKS both incoming and outgoing! So it looks like it's down to just my PC then.

I have spent hours with Tech department and digital assistand department at Directv. Today they are telling me as long as I use Firefox I will be unable to access my account. I have paid to have my computer checked out and was told that it was updated and the system was working fine. How to I get Directv to recognize my system?

Lots of problems migrating from Windows Live Mail. I've imported my contacts, but they are scrambled. The columns contain the wrong information. Is there any way to unscramble them?? Your "Help" often tells me to click on something that does not appear on my computer. Very frustrating to go through help procedures that lead to a blank wall.

I want to send a message to a lot of people as BCC letters. The default address is TO. It seems I have to change each one separately and manually to BCC. Very tedious work. Is there a way to rubber-band them and change them all to BCCs with one action?

Would it be possible to render the weeks in the calendar vertically rather than horizontally? I would love to have the ncal-like layout of the months. And also a month or two to see ahead, ideally to see the current month and two following months. Thank you for considering this feature request.
