I don't have an error code.

I am using TB 152.0.1 on Windows 11 Home 10.0.26200 Build 26200 I want to have TB on my Galaxy Tab 6 lite, and/or Huawei P20. I have the app installed on both devices, but whenever I try to scan the QR code under 'export for mobile', neither device locks onto it.

I know this problem has been reported before, but what I can do to make it work? Is there a setting I need to check/change, what is that setting, and where do I find it?

Grateful for any help, thank you

I have selected Export for Mobile.

I click on the Import Settings: Try to scan the QR Code from my laptop which says 1 of 2 QR Codes and I get nothing. No pop-ups, no approvals, it just sits there. Clicking done takes me back to the main screen.

PRELUDE: I have Thunderbird (TB) Version 152.0.1 (64-bit)

I have 45+ email addresses, some at various different domains, 8 (was 10 yesterday) Email accounts with Shaw that was taken over by Rogers. It's been a nightmare. I now have TB working almost as it should, and am use to but, one account has issue.

I tried to format this so it's easy to follow, but more formatting is not available so please see the pictures attached. Pics are self explanatory, but in case, pic 1 shows 3 accounts. The address with issues is the middle address (fake-two (faketwo@there.xy). The other 2, fake-one and fake-three have all their folders.

ANSWERS to possible questions: I used a outside mail to send/receive to/from fake-two. It receives and sends Email.

None of my sent emails are accessible. When I go to the sent folder after sending an email, the emails are not there. Same with deleted emails. When I go to that folder, they are not there. Why is Thunderbird email so overly complicated? I think I need a better email provider. I am only using it because gmail will no longer support 3rd party emails (for my business.)

I've had a Thunderbird email account for years. My laptop quit, so I've set up the account on a new laptop. I discovered that I hadn't saved my Thunderbird password, so I followed the procedure for "forgot password". This included a new p/w, and I also got a Mozilla PIN (for future Microsoft Password Manager use), and got a Mozilla Account Recovery Key, again for future use. But I can't log into my Thunderbird account. I get the message "Authentication Error" (Wrong p/w, email, etc.) Changing IMAP / POP settings didn't help, though I did go with the recommended IMAP setting.

Any suggestions?

New W11 Pro pc, so new installation of Thunderbird. All profiles and folders moved over ok, but the Bin folder is an issue (main Gmail account IMAP). In my previous Tbird installation, I was able to right click the Bin folder, and be given the option of emptying said folder. Not now. The Spam folder does have the Empty option. Pics illustrate the folder list, what happens when I right click the Bin folder, and what happens when I right click the Spam folder, which does have the 'Empty Spam' option. I can highlight the messages in the Bin folder and delete them that way, but the right click option is shorter, easier... The only item I can find in the Thunderbird help pages tell me to delete the Trash and Trash msf folders in the profile - tried this twice, with no difference. It's a little frustrating... Any help would be welcomed, I guess I'm missing something really simple...

TB152.0.1 (Windows 11 64-bit) add-ons/extensions not working

I've just transferred my profile to a new computer, for which I downloaded TB152 (had been running TB128), and no add-ons/extensions work. Of course many were rendered inoperative with the update, but that's not the issue, because:

  1. Even those which claim to be compatible, or were updated since the transfer for the purpose of extension compatibility, do not work.
  2. Moreover, when I invoke the Add-ons Manager to inquire about the various non-working extensions, none of the links (which can be seen and read by the OS), can be invoked or even copied (to be, for example, pasted into a browser window).

I went through the standard [[Mozilla Support diagnostics|https://support.mozilla.org/en-US/kb/hyperlinks-in-messages-not-working]] and found no answers. Can someone suggest a next step?

Trying to understand why this problem is related only to the extensions, I examined the profile's "extensions" folder. There are 40 .xpi files (same as the number of mostly-disabled (and mostly-expired) extensions in the Add-ons Manager), along with a subdirectory named "staged" containing 7 empty folders with what appear to be .xpi filenames - though none of those empty-folder-filenames match any of the .xpi files in the parent "extensions" folder. Because the "staged" folder has a recent timestamp (apparently the last time TB shut down), it seems to have some significance to TB operation - but what can be the use of it is more than I can see. What is the significance of that folder and its contents?

Two final (and possibly related) questions about this "extensions" folder:

  1. Is there any way to relate the <filename>.xpi to the name in the Add-ons Manager?
  2. Since nothing in the "extensions" folder identifies which are enabled, there must be some file containing a functional description of the folder's contents. Where would that be?

Grateful for any pointers, -John

For a week or two I haven't been able to send any email from Thunderbird. I use smtp.gmail.com as my outgoing server, and have it configured using SSL/TLS on port 465 with Oauth2 authentication. I first saw this on an older TB version, but have now updated to Thunderbird 152.0.1 on MacOS Sequoia 15.7.7.

When I try to send email, a dialog pops up saying "Enter credentials" for my account, then "Verify it's you". When I click on Next it asks me to "Complete sign-in using your passkey". I believe at this point another window is supposed to pop up and I can use a fingerprint to enter the passkey, but that window never pops up. I have tried 3 different default browsers: Firefox (my usual one), Google Chrome, and Safari. All behave the same. Firefox might be suppressing Javascript, but the other two certainly aren't.

Is there some system security setting that might be preventing Thunderbird from opening a window in the default browser, or does Thunderbird maintain its own record of the browser? Any other suggestions on how to get the passkey challenge to appear?
