1. Enable the search box to the right side of URL box in browser UI.
2. Open new tab (empty URL box).
3. Press TAB.
4. The search engine SELECTOR becomes highlighted, instead of the search INPUT.
5. Web application software developer is blocked from typing search query right away.
6. Must press ANOTHER TAB.
7. This breaks the workflow. It never used to do this, you could type immediately after tabbing ONCE.
8. Search is disabled in URL box to facilitate local domain resolution/error and NOT trigger fallback searching.

Please revert the behaviour to normal, and make the single TAB operation focus on the search INPUT.

Can get(POP3), but can not send emails to a newly created personal outlook.com account.

the following error occurs when trying to send mail: Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)

all my setting are correct per thunderbird and microsoft:

  (smtp-mail.outlook.com, port 587,  STARTTLS, OAUTH2, xxxxx@outlook.com)

thunderbird error log file contains the following: . . . mailnews.smtp: S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox.

Based on my understanding its seems thunderbird is using SMTP AUTH instead of OAUTH2 as required for newer personal outlook.com accounts. Is my assessment correct? If so, is there a fix?

Why is there not an option to say "no" to Firefox automatically loading when you restart your computer? There is only "yes" or "not now". I am not interested to my internet browser loading and opening once I have restarted my computer. I use my computer for much more than browsing on the internet. I am tired of always having to click the "not now" option to only have it show up the next day or two days later, where I then have to click, yet again, the "not now" option. I even went into Firefox settings and have not found an option to "op out" of this particular feature. Can you please add a "no" option to automatically opening upon restart.

i used to use CCLeaner browser, but I have changed my default browser to Chrome. However, when I click on a link in an email in Thunderbird, it still sends me to CCleaner browser. I can "copy link address" and paste it into Chrome, but it would be more convenient for me to be able to click on the link and go to Chrome directly. Where in Thunderbird can I change this?

Whenever I try to search my various emails for some text, at least 40% of the time it shows me the attached message. I'm on Version 149.0.1 but it's been happening ever since I installed Thunderbird (maybe 4 or 5 months ago?) My first move is to check that I haven't mis-spelled the word I'm looking for (which I usually haven't) and I definitely know that the word is valid for one or more emails. So why does this message keep appearing?

Previously I'd been running an old 32-bit version of Thunderbird (which I don't have installed any more) but I don't remember ever seeing this with the older version.

I would like to have a text label on or in place of the Get Messages icon in the tree header.

I found this suggested procedure: 1. Right-click on Toolbar 2. Select "Customize" 3. Select desired choice in "Button Style" 4. Select "Get Messages" 5. Click on Save

Nothing happens!

I asked this in alt.comp/software.thunderbird and received several conflicting replies, none of which resolved the issue.

how do i delete or remove the message about could connect error

Contributor note: See also /questions/1576275 for the detailed error message.

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.

I am trying to add one of my Google email accounts to Thunderbird. It brings up the "Sign in with Google" window, which is normal. But instead of "Sign in to continue to Google...", it says "Sign in to continue to Mozilla Thunderbird Email". Which then generates an error: "Error 400. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." I've not ever experienced this issue before; adding a Google account has always been super easy and straightforward.

I am considering changing from my current email server to another. How do I move my TB account from one server to another? And does the physical location of the server have any effect on my account? I am moving from the US to Europe.

How to close status bar of the search bar when inputting? When I input a search key word, below will show a status(or a remind) bar. This is very annoying, how to turn it off? Thank you!
