Hello community,

at my place of work no one can send or receive mail anmore using Thunderbird. The problem suddenly appeared last monday. No changes regarding the network or settings in Thunderbird happened prior to this.

Here's what I tried so far and things I can rule out:

  • same problem appears on all devices (desktop and laptop PCs) in our office
  • our work mail server is online and working, I can access everything using the webmail-interface in the office network
  • new installation of Thunderbird without any profiles and fresh account confguration doesn't solve the problem
  • I can connect to our mail provider and send and receive mail when using my home network or my personal phone hotspot
  • I can connect to my private mail provider using Thunderbird while in the office network
  • troubleshooting mode doesn't solve the issue
  • renewing the internet connection on our router temporarily/once allowed some devices to receive mail
  • pinging the mail server (mailserver.[workdomain].de, no specific port) via command line was successful while Thunderbird was unable to connect to the mail accounts

IMAP-Log returns the following error codes:

  • D/IMAP URL failed with code 0x804b000e
  • D/IMAP URL failed with code 0x804b001e

I would be glad if somebody could help me out. If you need any more details I'll provide them. Thanks in advance!

I was looking for information (search engine Duck Duck-Go) about plants and suddenly I got a massage which says my iphone is hacked. I was not able to acrivate any button, besides the ok button, which I did not trigger of course. I tried to find info (pc) about the address but I shows a black screen. Than I removed firefox and re-installed it. Now the massage is gone. I have no idea where this massage comes from and if it will install malware if I would have used the ok button. It might happen again and it would be nice to know what to do Thanks in advance….

WHY can I not remove the pre-loaded search engines?

I have no desire to interact with Google, Bing, or Perplexity, and as a rule I don't want outside parties (such as Firefox/Mozilla) deciding for me which search engines or other service providers I see advertising for. (And yes, seeing that "G" logo somewhere is advertising for Google.) I'm assuming that these companies are paying to be pre-loaded as search providers in Firefox, and I understand that Firefox needs this financial support if it's going to continue providing a browser.

After upgrading, I've always gone into the settings and removed these search providers - I don't want to see them offered as search options, and to be honest, I don't even want to see their names in the settings screens.

Now with Firefox 152, I find that I'm not able to delete these pre-loaded search providers anymore. I can turn off a switch to disable them, but there's no way to totally delete them from the list anymore. There's even a [in the documentation] which explicitly says that the pre-loaded search providers cannot be removed, only hidden.

'WHY can I not delete them?

Is there a technical reason, i.e. would the browser stop working if they were removed? Are some companies paying extra to not be delete-able, and it just happens that every one that's pre-loaded in Firefox 152 decided to pay the extra money? Or did Mozilla just make an arbitrary decision to reduce the level of control that users have over their own browsers?

I noticed that ‌import‌ bookmarks is already available in Nightly, but ‌export‌ bookmarks is still missing on Android. I'd rather not use Firefox Sync for privacy reasons, so a native export option (e.g., to HTML) would be greatly appreciated.

When I needed to find my user name and/or password for a website I would go into the privacy and security area, scroll down to saved passwords and they were all there in alphabetical order. With the format change I can't find my list now. I've looked in the password section and privacy section and don't see where the "saved passwords" are. Can anyone help me?

Over the last week or so, I have received an enormous amount of scam, but no matter how many times I "train" the filter, it doesn't work.

I have just received another 3 from this site: mid:02guhjkj6-ABMcSHN6Or-JiC-000000@eu-central-1.amazonses.com, which claim to be from Madasafish Security>security@qi9adgongzenElptrum.de

I have tried on several occasions to follow the manual instructions how to deal with the spam, but I find it so log-winded that my non-techie brain, which is not wired for these kind of things, gets tired and I give up. If anyone has a more intuitive approach how to deal with this, I would be very appreciative. I have marked sites multiple times as spam, but the spam control ignores me!

I did not change anything, the sending error occurred suddenly , all my settings IMAP Mail Server Port 993 SSL/TLS OAuth2 and SMTP Port 465 are still set to default. I changed also the SMTP to an new shown default 587 but non of this settings resolved the problem
