When I tried to set up a second email account (peters-up40@t-online.de), I received the following error message: "login to the server failed. The configuration, username or password may not be correct." The new address is correct, it was confirmed to me by Telekom. The PW is the same as in my first email address. What did I do wrong? Regards, Uwe

I had to reformat a hard drive. Unfortunately, my current Thunderbird profile was erased. I have a 7-month earlier profile backed up, and my current emails are still available from Spectrum webmail. Can I re-install the old profile, and download the newer emails from Spectrum to create a new profile? What is the safest way to proceed and not lose emails? Thanks!

When i do update my configuration settings changing by itself. Example, "browser.cache.disk.enable" is "false" but after every updates its always changing to "true". This happens only after updates.

Hello! After installing update 129.0.1, in the profile folder, along the path: AppData/roaming/mozilla/firefox/profiles, a folder "extensions store menus" appeared, it contains the file data.life.bin, which changes its modification date as if it was synchronized when the browser closes. I would like to know if anyone else has this folder and file? . I checked the file for viruses, it is clean. Thanks in advance for your answers).

updated from 128 to 129 and now T-Bird is broken. First it opens a second T-Bird apt instead of the original apt. Second the graphics are screwed up as the top tool bars are white with very unreadable faint buttons, so I can not pick and chose , and when replying to an email the header graphics have too much dark which covers the formatting tools and other parts of the header. There are several other problems that I have not found yet as I have only had this update less than 24 hours.

See the screen shot of my broken version 129 of T-Bird. It needs fixing and fixed quickly. How do I revert back to 128 which worked perfectly.

I have installed Thunderbird and want to set up an email account' . I enter: Name : Roger Keelingling@f2s.com pw : ******** (I have checked this visually and tried many times - must have got it right once)

I get the message "Thunderbird failed to find the setting for your email account"

According to f2s the settings should be as attached. I have tried manual setup with many options but nothing connects properly (or at all). On some attempts I get a message "The certificate for inmail.f2s.com is not valid for this server" (flashes up too quickly to read accurately). Any suggestions on account setup?

I recently created a new profile, changing from POP3 to IMAP in order to meet the new Microsoft security requirements. All went well until I went to change my address book backup copy routine to access my address book in the new profile.. I cannot find any .MAB nor .SQLITE files anywhere! My address book is out there somewhere, as I can bring it up in Thunderbird, but I cannot find the actual file. What's going on?

Running TB 115.12.2 (32-bit), Windows 10 10.0.19045 Build 19045

Thunderbird used to come with spell checking ready to go.

I have just installed the latest version of Thunderbird and have written a few words including a deliberate spelling mistake and nothing happens. I get the spell checking window but no message I press recheck text and nothing happens

The check spelling while typing box is ticked.

Is a dictionary pre-installed or do you have to install one first?

Please resolve.
