Hello,

We are having a problem with migrating a profile to a new PC. We saved the profile on the old PC and then loaded it onto the new PC. When we open Thunderbird with the profile transferred to the new PC, all the mailboxes are displayed correctly and everything works as expected. Then when we close Thunderbird and reopen it, we see the mailboxes but in which no data is present. We have tried the procedure again by multiple means but we always end up with the same result.

However, this is a procedure that I have carried out many times within my company and I have never encountered this problem.

Do you have any suggestions please?

Thank you, Sincerely,

I got a password manager app but ended up uninstalling it. In the process, the normal insertion of my user name and password on accounts I use no longer happened. The information is still in my password file on my iMac, but when I access, for example, my bank, I have to enter my user name and password by hand. Before I tried the password manager (Roboform), there was no problem.

I accidentally activated 'block element' for my homepage 'www.msn.com'. Now the site comes up blank. How do I reverse the 'block element?

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

I am currently using FF v133.0 and I want to downgrade to v130.0. I tried this once before and could not get the 'Profile' to activate and reinstall all of my settings, bookmarks, add-ons, etc.

Please provide step-by-step instructions for doing this. Any assistance will be greatly appreciated.

I am using Windows 10 64 bit.

Thank you.

I am trying to turn off the message that I get saying "Mozilla Thunderbird Email wants to access your Google Account". I cannot figure out how to turn this off.

Just make it stop. I reply to deny but it keeps coming up.

Just make it stop.

Hello, I'm currently using a Macbook Air, Early 2014, that still works perfectly fine for my needs. But it runs with OS X 10.9.5 and Firefox 78.15.0esr, that unfortunately can no longer be updated. That wouldn't be a problem to me since I do a very limited use of the computer, but now I'm getting the message "Your Firefox may start to have problems on January 14, 2025 since updates are not available for this OS". What should I do if I still want to use this device with Firefox to browse the internet? If it is impossible to keep using Firefox, any suggestions for an alternative browser that may still work? Safari is no longer an option. Thanks a lot for any and all replies

Thunderbird Mails junk controls are themselves junk - they do not work. Each day I mark a message from a regular sender as "not junk" and the very next day or two later the next message from the same sender is also placed into junk. Why? Is there a way to permanently disable your junk controls. I have always enjoyed using Thunderbird. I have recommended it to friends. The calendar is an awesome feature. When this new system of controls arrived which I seem to have no control over I have changed my mind. Can it not be turned off? Thanks, John

Is there a way to delete an email from one computer without it being deleted from another computer? I have my email on 2 computers. I don't want an email deleted from both computers.

Using Windows 11 and recently activated Windows Security and removed McAfee antivirus. Since this was completed, MS Outlook would not send emails so I was instructed by my ISP to switch to Thunderbird. Now using Thunderbird and I am able to receive emails but cannot send. Attached are the mail settings that were given to me by my local cable company (MCTV Ohio). Any ideas how to fix this so that I can send emails? The message just "clocks" showing sending for hours...never actually sends the email. I know the issue is not on the end of the ISP because I am able to send on their web, just not through Thunderbird.

I have not changed my email accounts or my Google & Microsoft usernames or passwords. A few days ago when I started Thunderbird, two Google pop-ups arrive reading "Mozilla Thunderbird Email wants to access your Google Account" demanding that I deny or allow it. Why might this be happening and how do I stop it? This does not occur with other email apps such as Outlook for Windows.
