For the last two or three weeks I have had problems with Thunderbird not downloading e mail from Charter for a few days and then it does for another few days, then it doesn't. Back and forth until the last two days it just seems dead, doesn't receive or send anything. What do I do?

Какое то время назад, я уже писал, что перестал работать VPN в браузере Mozilla. После этого, через короткое время, VPN включили! Сейчас, снова, VPN перестал подключаться и работать. Когда же будет стабильность, в работе этого VPN? Включите, пожалуйста!

When starting thunderbird, the program cannot find my e-mails and does not respond. It is frozen. deinstallation and new installation did not help. The version i do not know because I cannot open the menue.

Hello everyone! I also had the error, it randomly started moving messages to folders. I deleted everything, reinstalled (155.0.1), started building message filters. I'm at 29 now. (Gmail account) now I'm not getting new messages. For every filter I get a message saying that the filter could not be applied. No messages are coming, anywhere. What's going on?

All my new incoming e-mails are ending up in the trash instead the inbox. This happens since about a week. I have to move all e-mails from the trash to the inbox. There are no active filters, so what is the problem? Also the layout has suddenly changed. Please help.

Thunderbird Email: since Sept 2 Thunderbird update 155, my incoming emails are no longer coming into my inbox with my domain host provider webnames.ca. My other staff members have no problems since the update. The only unique thing I can think of is that with my host provider is that I automatically forward incoming emails to my gmail account. Some other staff automatically forward thunderbird email to another thunderbird email of the same domain name without an issue. I can get incoming emails from my other thunderbird accounts ending in the same domain name. The emails do show up in the forwarded gmail account.

I routinely am not able to open registration to conferences or other links to long web addresses. This screen message from Firefox appears:

"Server Not Found

Firefox can’t connect to the server at gi9zc6sab.cc.rs6.net. What can you do about it?

   Check to make sure you’ve typed the website address correctly and try again in a few moments.
   Check your network connection.
   Check that Firefox has permission to access the web (you might be connected but behind a firewall).

Recently I posted about this problem here: https://support.mozilla.org/en-US/questions/1580858 In sum, I was having problems both in downloading messages from the Spectrum server and also with sending messages. I've attached screenshots of the error messages.

Matt and David kindly posted some helpful responses. The problem then seemed to spontaneously solve itself and I breathed a sigh of relief. Then a few days later it re-appeared.

This time it's not quite as bad in that I'll get the error messages but then usually a few minutes later I can download the messages or send an email. But it's still a real problem.

I called Spectrum again and this time the rep was adamant that if I can still use the Spectrum webmail feature (and I can), then it's not a Spectrum issue.

Last time Matt asked about my antivirus. I use Windows Defender (and occasionally do a manual scan with Malwarebytes free version), so if I understood him right, I should be OK as far as antivirus interference.

Matt also suggested I set TB so that I download messages at startup and every 15 minutes. I was set to every 10 minutes so I changed it to 15.

Matt said for me to check the Activity Manager. I've attached a screenshot of what that showed a few minutes ago. But I should note that this was after an error message displayed but my email downloaded anyway.

Finally, Matt said I should check the Error Console (Control + Shift +J). I've attached a screenshot of that. He also said I should use the trash can to clear it, so I did. He then said to press Shift + F5 to attempt to get my messages. But on my laptop, F5 just dims the display so no dice on that. But I have a second laptop and F5 is "neutral" on that one so I tried it there. I didn't get any new error message.

However, one of the screwy things is that sometimes I get all my messages as normal, but only after the "Can't connect to the server" message displays. And that's what happened with my second laptop above.

I hope I've provided better info. this time. And I hope you gents can help me with this mess.

Thanks,

Andrew

Since this morning there is no sign of my emails accounts and majority of functions appear disabled, it never happened before. Can somebody explain what happened?

Please check the image attached

I have cleared all logins and ALL browser cache and cookies, checked for updated version (running 155.0.1 for Mac OS) and restarted the browser. But still get a BAD REQUEST error when trying to access someone's Calendly page. I can load the main website of Calendly, but it will not load specific person's calendar.

I tested this in Chrome and in Safari and there are no issues loading someone's Calendly page. Here is an example account. https://calendly.com/rickcoughlin

I have also tried this in Private Mode. Can someone help?

thunderbird Version 153.2.0esr (64 bits) Hello, following an update, email retrieval is no longer working for an account with a ....@rocketmail.com address. Thunderbird opens a "Yahoo" login window, but when I enter my address, it is flagged as invalid. Fortunately, I am still able to log in to this account via a web browser. (Google translation from French to English)

In the Settings, the "HTTPS-Only" feature seems broken. There is an option to 'Don't enable" this feature, but that doesn't make any difference. I can get to an "http:" site using any other browser, but not with the latest Firefox.
