I have a downloaded application of Thunderbird 78.6.1 on my computer from 2021. With my new Windows 11 Pro I had to download and install 138.0 (64 bit) and I'd like to go back to 78.6.1. Can I install it by running the application from the old download? If so, do I need to uninstall 138.0 first?. Will my address book and emails be safe? Is there any profile mix up I should be concerned about?

To the right of Other Bookmarks Firefox still says "finish Setup" but I've checked everything and run the setup. I can't seem to do anything to correct/clean up this?

Thank you.

After the last update Firefox ESR 115.23.0 the menu on the website: https://connect.garmin.com/modern/home is not displayed correctly. Can you fix this?

Hi, I've successfully downloaded and installed Firefox on my HP laptop with Windows 10 and now attempting to download and install the Thunderbird email client. On Thunderbird.net when I click the Download button, the Donation Page pops up (and I made a donation) then closed that window. I'm then on the Thank You page but there is no prompt to install, so just stuck on the Thank You page. Thunderbird is not appearing in my downloads file. Can you please help?

Your update has erased every bookmark I had, no gmail, no YT, NOTHING is left. my history is erased. Thank you for destroying my computer. WHY DID YOU DO THIS TO ME?

I was auto-updated overnight to 128.6ESR 32-bit. My unit is Windows 11 64-bit. When I called up the program later, it did not load my profile of 35GB, neither its accounts nor folders nor email records. What do I do to retrieve the profile?

Old computer crashed and all but burned. The Geek Squad was able to recover most all data off the old hard drive. Down loaded a new Thunderbird to the new computer, so I can get email from old email address. Now I am trying to get my old account data and emails to work. I cannot get the old version up to work where I can check old emails... Note I have another email account that is a gmail acccont that is not tied to Thurderbird.

SOS. Please help if you can.

New Firefox update from yesterday has wiped out ALL bookmarks and appear irretrievable.

This happened once before but I was able to restore them.

This time, every bookmark folder is empty - restoring history seems to be available but only goes back to early today.

I have a new computer with Windows 11. My existing PC has windows 7 with Thunderbird Version 115.18.0esr. Will https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

work to transfer settings to the new conputer? If not, how should I do it?

My wife, all of a sudden, was unable to download email in her Thunderbird Comcast account. After much fussing around I deleted profile and tried to create a new one. I have tried many combinations of entries in the profile form. Attached is an image of one form set-up page.

Sometimes when I press "Done" a comcast page opens and I log in. But I always get the yellow failed message.

Is there something wrong with my information in the boxes?

What am I doing wrong?

Hi there, I have a problem with Thunderbird, and was hoping that someone could help.

I have it installed on a bunch of computers, but there is this one laptop that is giving no end of grief.

Currently running Linux Mint 21.3 - everything up to date. Thunderbird installed using Synaptic.

Thunderbird shows version 102.2.2 - which is different (older) than all other computers. The automatic update fails. I have tried re-installing from Synaptic, no joy.

This is probably something simple, but it is proving to be driving me crazy.

Any ideas what is going wrong and how to fix it?

Thanks in advance.

Hi! I'm currently on Mozilla Firefox's Version 138.0.1 for 64-bit Windows 11, but I don't have the new features for tab groups or profile customization. I checked for updates and disabled my extensions, and still no options for either of the new features appear. Is there a way I can get these features activated on my Firefox? Thanks!

Hello, this am I'm unable to access my e-mail because I need to upgrade to the newer version of Thunderbird. How do I find which version I have-older than 60.0 or the newer 60.91?

Sincerely, Stan
