Both FireFox and Thunderbird can't connect to server anymore

I-Firefox Crashing and slow performance
Thunderbird2015
Thunderbird2015

Hello,

I'm facing a two-fold problem:

1. Firefox (138.0.4, 64-bits): when trying to open a website the URL is loaded in the FF-tab, but the screen stays empty

2. Thunderbird (128.10.0esr, 64-bits): downloading messages isn't possible anymore. When sending a message I get following error message (in Dutch):

Verzenden van het bericht is mislukt. Er is een fout opgetreden bij het verzenden van e-mail: fout met uitgaande (SMTP-)server. De server antwoordde: Cannot connect to SMTP server 127.0.0.1 (127.0.0.1:54601), connect error 10061.

Translated to English:

Sending the message failed. An error occurred while sending the email: Outgoing (SMTP) server error. The server responded: Cannot connect to SMTP server 127.0.0.1 (127.0.0.1:54601), connect error 10061.

I did a ping with following result:

C:\Users\<user>>ping 127.0.0.1

Pinging 127.0.0.1 with 32 bytes of data: Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Ping statistics for 127.0.0.1: 

   Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds: 

   Minimum = 0ms, Maximum = 0ms, Average = 0ms


I didn't make any changes to FF and/or TB, and my wild guess is that the necessary Mozilla servers aren't available anymore, due to:

May 21, 2025

No incidents reported today. May 20, 2025 Mozilla Monitor website will be down for 2 hours starting 5/20/2025 at 6 AM PT. Completed - The scheduled maintenance has been completed.

If somebody could step-in, that would be great!
