Trying to install an older vesion of Thunderbird, but keep getting this error: Could not get OAuth2 details for hostname =imap.comcast.net

I would like to uninstall my Thunderbird 32-bit and then install the 64-bit version. Or could I just install 64-bit on top of 32-bit? Are there any disadvanteges with going to 64-bit?

Why thunderbird needs a specific version ? Why the newest versions aren't compatible with windows 7 ?

I have more than 100 pc running mainly Mozilla tools on windows 7 which does the job perfectly. I don't want to pay $15000 fees for an unnecessary upgrade.

What new functionnalities windows 11 brings that prevent Mozilla to compile the same versions for all windows OS ? This forces people to abandon their windows 7 and to pay fees to Microsoft. I understand the later, he does his business. But why Mozilla helps it ?

I just bought a new Mac mini. My info/programs were transferred from old computer to new, but now my Thunderbird mail app shows as corrupted. Should I trash the old corrupted version before or after installing the new? I can't find version here because old version won't open for me to look.

I have a new (to me) Microsoft Surface pc with an ARM processor. After a very recent update to Windows 11,my entire Thunderbird installation has disappeared and I have been forced to use the Web to access my emails from Posteo.de Can you assist me please?

Greetings,

I've been using Thunderbird for more than a decade. My old version quit on me, I can't get e-mails. The error message I get is: "The certificate for inbound.att.net:995 does not come from a trusted source." I was hoping someone would get to the server and fix the issue, but it's been more than a week now and still no service. So I took it upon myself to download a new copy. I get to the donation page and donated $20. I attempt to download and I'm taken to another donation page and I can't get passed it without making another donation.

I'm stuck and need assistance.

Thank you, MSuñer

I have been using Thunderbird for over 12 months on my old computer. I have just bought a new computer and I can't install Thunderbird on it. The process recognises my account settings, but when I press CONTINUE it gives me the error message below. The Thunderbird version on my old laptop is 155.0. I imagine that the current version I'm trying to load is a later version.

I have an extension that I depend on and it is not compatible with the current version of Thunderbird so I need to backup until it starts working again. How can I download earlier version of Thunderbird?

Thunderbird 143.0.1

My TBird updated this morning and everything turned to crap...

I have TBird set to check for emails every 15 minutes on 4 accounts. There are also 3 accounts that I monitor and check manually...

As soon as the 143.0.1 update touched home base TBird went ballistic. Withing in seconds of it checking for mail on the four accounts it then started deleting the accounts. Any mail was down loaded then poof!! No mail and No mail account. I had to crash dive my laptop to to stop it. Spent 3 hours trying to recover the emails and accounts and managed to reclaim 3 accounts out of the 4 but lost all the emails... After all that effort I was totally peeved and decided to uninstall TBird and revert to an older version... The icing on the cake TBird wont unistall because the YES button on the TBird Helper window wont activate...

After more than thirty years of supporting Firefox and Thunderbird... You have really dropped the ball with this one... As far as me getting an email when someone answers the thread... Good Luck...
