Thunderbird Community Forum

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).

I HAVE CHANGED NOTHING & CAN LOG ON SERVER WHILE IN THUNDERBIRD SETTINGS, BUT WHEN ASKING FOR NEW MAIL AM TOLD "LOGIN TO SERVER WITH (MY EMAIL) FAILED". THIS IS SUDDEN SINCE UPDATING TO LATEST THUNDERBIRD. LOGGING ON IN FIREFOX WITH SAME INFO IS FINE! THANKS

Yesterday, downloading emails got stuck because it couldn't download an email. I tried this multiple times and then it said it couldn't connect to my email server. I tried Repairing the individuals folders but the problem persisted. I looked the problem up, and one of the recommendations was to uninstall Thunderbird, the profile folder, and install it again. When I launched it again, it told me it couldn't find a profile, so I went to the app data folder and restored the folder containing my emails etc. I reconnected it to my Yahoo Mail server. I started TB this morning, and it does the same thing. It tries to download 205 emails, when I know I haven't got that many from yesterday. It still gets stuck on email 21, so I close it, open it, close it, open it, in which it checks again, and I go round and round in circles. It is now telling me that it has failed to connect to the Yahoo server. Checking mail through the Yahoo site works fine. I am using TB 149.0.1 on Wiindows 11.
