I am receiving the following message: The RETR command did not succeed. Error retrieving message. Mail server.comcast.net responded: Message 9 expunged.

The message number does change each time I try to download my messages. Thanks for any help. Rob

During move of my 2022 mails, the system crashed, and the mails disappeared. I have an older back-up, but how do I get the 2022 mails back without disturbing the later mails

I installed Thunderbird 115.6.1 and it will not send or receive email. I uninstalled Thunderbird and scoured the Windows 10 Registry with CCleaner. When reinstalling Tbird 115.6.1 it works until I reboot then it fails again.

I have checked the serer setting for the Incoming and Outgong servers and they are correct.

My PC goes online without a hitch with Firefox, Tor, Vivaldi, and DuckDuckGo browsers. The Internet connection is solid. Note: Firefox was misbehaving in that it would not fully open some sights. In Windows Programs and Features I found and executed a Repair function for Firefox and that solved that problem. This saved me from uninstalling, flushing the Registry, and reinstalling. I thought it may clear the Tbird problem, but it did not.

I am quite technically savvy as I used PC since they were on the market and never ask for help until I've exhausted every possible fox. This problem is one for the history books and eludes me.

Error message is that the server is not responding. eMClient email software works without a problem as does using Web mail through Firefox or another browser. Your help is most appreciated, or a link where i may download a previous version of Thunderbird. Thank you, your help is warmly appreciated.

Hi,

I have a Gmail account and use the web browser version on my windows 10 laptop and the Android Gmail app on my Samsung S22 android phone. Prior to installing Thunderbird v115.7.0 (note I did not have an earlier version installed), the notifications would appear on both windows and the phone. Since installing Thunderbird on the laptop I do not get notifications on the phone. I have to open Gmail on the phone to see if there are new email message.

Any suggestions are greatly appreciated.

Cheers! Terry

Thunderbird hangs at checking mail server capabilities - this message appeared after Thunderbird crashed 2 days ago. Apparently messages are sent although that is not indicated but no new messages are being received ( ????? blocked). I have tried to reboot to no avail. HELP PLEASE. I am using WIN 10 if that helps and my primary server is SHAW.ca

I have problems sending multi-addressed emails. With a group of up to 10 addresses it works, but any more than that, the message is rejected. I sometimes need to send to around 130 addresses.

Hello,

I am experiencing a persistent issue with web browsers on my Lenovo Legion T5 26IAB running Windows 11 Home. Regardless of whether I use Mozilla Firefox, the browser frequently crashes. This happens at least once a day, and it seems to be unrelated to the number of tabs open or the specific content being viewed. I did the help -> diagnose mode without plugin and it crashed too, im not sure what this is realted to.

The crashes often present with an error message suggesting a failure in the new tabs or trying to load a old one, despite the fact that my system's RAM usage is typically around 60-70%. I have already updated the BIOS, Lenovo drivers, and NVIDIA graphics drivers, but the issue persists.

I'm seeking advice on what might be causing these browser crashes. Is it possible that there's a compatibility issue with Windows 11 Home? Could it be related to the graphics card or its drivers, even though they are up-to-date? I have not changed the power cable from my old PC; could this be a factor?

Any insights, suggestions, or similar experiences would be greatly appreciated. I'm trying to determine if this is a hardware issue, a driver conflict, or something else entirely.

Thank you in advance for your help.

After power outage, I had to reset my PC and Thunderbird is gone - says does not exist on this computer. Is there any way retrieve my emails ?

My PC is older and Windows 8. I do have a computer back up on an external hard drive.

Would my Tbird be there and how do I get back ?

Good afternoon, We are the developers of a web application and are experiencing issues with the tab constantly crashing in response to a variety of actions performed inside the app. We've spent the day trying to identify and fix the bug, but I'm beginning to think that the issue may be on the Firefox browser side, and not our application. You can check out some of our crash reports (some examples below): bp-4bd3f3b6-7ef5-4915-8fe4-9696b0240207 bp-fd284c7a-a42a-4fd8-a283-d9f3f0240207 bp-9958483b-3c49-402c-8276-928e60240207 bp-7da1af1a-d6db-4533-a5d1-fe4eb0240207

I just removed Firefox from my laptop completely and installed the old version (121.0.1). With that version I could not recreate the problem at all. It did not occur even once, even though I tested all sorts of different actions and scenarios for over an hour. As soon as I updated to the current browser version 122.0.1, the problem is back and the tab keeps crashing. Any idea what might be causing this?

Thank you for your help and best wishes, Anika

i use firefox on ubuntu and a dropdown terminal app called tilda. i configured the F1 key in the system to bring down the tilda terminal. it works in every other application, just when firefox is in front, the F1 key does nothing. it wasn't the case before, now it is.

Firefox uses 2.1gb of RAM with 6 tabs opened which is far more than it ussualy does and it sometimes just jumps to 2.5gb. ((Fore the Image) My task manager is in german so Arbeitsspeicher=RAM)

I currently use Mitchell 1 Teamworks Invoice Software to send emails to customers for vehicle repairs. Mithchell 1 uses Thunderbird. Unfortunetly I am unable to send emails and was hoping for a solution. Thunderbird is currently set up as my default email.

Hello,

We are using a Sharepoint site with an embedded page, and when clicking this page it brings us to this support article. Is there any way we can edit the settings in Firefox to allow for this page to open? https://support.mozilla.org/en-US/kb/xframe-neterror-page?as=u&utm_source=inproduct

I can not change password and connect to my gmail account after changing password. I try also change it in password managaer in settings

Polecenie STAT się nie powiodło. Błąd pobierania numeru i rozmiarów wiadomości. Odpowiedź serwera poczty pop.gmail.com: [AUTH] Invalid credentials.

Suddenly getting error message window titled "Send Message Error" Reads" Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.peak.org failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

Checked with ISP and they have not blocked or many any changes and verified the SMTP settings are correct. Port 465 Connection Security SSL/TLS Authentication Method Normal Password.

I also at times received a Tbird window in the lower right of the screen that I couldn't using the snipping tool on to same. Says something about reducing the cache which I did to no avail, going from what I gather is a default 15 to 10.

Was sending messages without issue this morning but now can't get past the above message. Can send messages using the ISP's Zimbra webmail. They have no knowledge of Thunderbird and do not support it. I've read what I could find but didn't see anything replicating my issue.

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

Firefox has been white-screen blocking my access to some common websites including CNN, Amazon and possibly others. No error messages, just a blank white screen. This is a sudden change and has never been a problem in the past. Chrome and Firefox on my other computers are not affected. I have cleared caches and deleted all tabs with no change in symptom. I've also checked CPU and memory resources and both appear normal. No sites are being blocked by settings either, though I would expect Firefox to give me a "This site is blocked" message of some kind if that were the case. How do I fix this?
