Authentication failure with SMTP-server

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'., exitCode=2153066805, originalMsgURI="

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

As stated in the question, messages older than 1000 days are not deleted (this is a POP server). This is on my Desktop which is my primary PC. I also have a laptop using Thunderbird with "Leave messages on server" but with neither option (Number of days or Until I delete them) checked. The purpose of the laptop settings is that since it is not my primary PC I don't want it to delete anything from the server.

I did quite a few searches and the closest thing I found was another user who had migrated to Thunderbird after using another mail client for years, and it sounded like after they installed Thunderbird, they imported their old emails from the old client and then began using Thunderbird. The explanation they got was that any emails that had not been downloaded from the server by Thunderbird would not have a download date in Thunderbird and would therefore not be subject to the "older than xxx days" setting. That scenario doesn't apply to me because I have been using Thunderbird exclusively for at least 5 years, so all emails on the server that are less than ~1825 days (5 x 365) were downloaded by Thunderbird. All emails older than 5 years have long since been deleted from the server manually.

Either I am misunderstanding the "For at most xxx days" setting or something is not working properly.

I've got a really old MacBook Pro that's still running 10.13, and Firefox has started displaying a nag screen telling me that this version is no longer supported, and to install a newer version of MacOS.

Is there something in the advanced settings that will stop it nagging me? I now know it's not going to get any more updates, there's no need to keep telling me every 20 minutes...

(Note to the devs: a "don't remind me again" checkbox would be nice for things like this!)

For several sites, when i check 'trust this device' it doesn't work. next time i signin it still requires 2fa from the site. i've checked and the certificates do exist as i get a message saying already exists when i try to import. this is a very user hostile function. I do not have this issue with Chrome or Microsoft Edge!!!!! i hate to begin using one of these vs Mozilla Firefox to get around this but i may have to do so. my wife and i share access to critical sites so if i need to see her info or she needs to see mine, we both have to be available in order to access the site. Mozilla Firefox 'bug' is requiring us to do so and it doesn't satisfy our requirements. any ways to solve this issue is greatly appreciated. so far no 'searched' solutions work.
