Hello, I did a mistake, I installed 2 instances of Thunderbird, one pointing to the system disk and the other to the user data disk. How do I remove the instance that points to the system disk? Best regards

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?
