When I attempt to access the Add-Ons service through Thunderbird, it brings me to an HTML page (https://addons.thunderbird.net/en-US/thunderbird/search/?q=lastpass&appver=147.0.1&platform=Linux) reading

> addons.thunderbird.net > Performing security verification > > This website uses a security service to protect against malicious bots. This page is displayed while the > website verifies you are not a bot.

with the following footer: > Ray ID: 9d07fae58cabaefb > Performance and Security by Cloudflare

It will attempt to connect to Cloudflare to verify a Captcha, but the Captcha itself never renders, and after a period adds the following to the text:

> Why is this verification taking longer? >This verification can take longer due to an older computer or a slow internet connection. > What to do next: > # Wait briefly. Refreshing the page will restart the security verification and may take longer. > # If the verification still does not complete, refresh this page. > # If you are still stuck on this page after a page refresh, refer to Cloudflare’s troubleshooting documentation for more help.

After another period it then cycles the verification page. This continues as long as the tab remains open.

Opening the link listed above in Firefox opens the Addons page as expected.

Similar Captcha pages open on launch, as well as when accessing support or attempting to create a Matrix chat account.

There is a potentially related issue in that images and some icons are not rendered. I will make a separate post asking for help with that if it is not related, but it seemed relevant to mention.

The problem has existed for a long time, and I have checked existing responses without finding a solution, but I didn't get around to asking about it until now.

I am using Thunderbird v. 147.0.1 (64-bit) for Linux with no extensions installed), connected via AT&T broadband service with no proxy set, running under Manjaro 26.0, kernel 6.18.8-1, with the XFCE desktop environment (that last is only mentioned for the sake of completeness). I am using GUFW for my firewall, but the problem persists when the firewall is disabled (something I do not wish to do regularly in any case).

Yesterday, out of the blue, one of my Spectrum email accounts asked me to sign in. I tried entering my existing credentials several times, but failed to sign in. I tried to recreate the account, but, it fails each time with "Thunderbird failed to find the settings for your email account". I tried using the account hub and it fails with the same message, with a sub message of "can't find a server".

I've been on the phone with Spectrum 5 times in the past 24 hours. They claim that it's a Thunderbird problem since I can access the email in question if I go through their web interface.

Can anyone help with this?
