I have 2 windows 10 computers both with Thunderbird. One computer never has trouble with getting emails. The other shows every day "Login to server mail.hoster905.com with username cnc@lcgnm.com failed" I have reset this one password at the server, entered the new password in Thunderbird and can the get mail. That day only. Next day same problem.

Thunderbird has suddenly stopped pulling in email, please help. It just says 'Checking mail server capabilities'. I have changed no settings at all. Webmail works. Email on my phone works. So it's not the ISP or the server or anything like that. It's just on Thunderbird where I can't do anything, but I've not changed anything so I don't understand.

When I try to send email it fails and says: Sending of the message failed. Unable to communicate securely with peer: requested domain name does not match the server’s certificate. The configuration related to mail.mandyhaggith.net must be corrected.

So please can you tell me how to correct the configuration?

Thank you for any help you can offer.

Best wishes Mandy

Until a few days ago, my Firefox would save all the tabs from the previous session. But now it does not, and I still have all the necessary settings enabled. I noticed that it will save the previous session IF I use the Firefox "EXIT" from the "File" menu. However if I use close the session using the upper right hand corner Windows close box (where the "X"), it does NOT save the tabs from the session. I also notice that when I close the Firefox window using the Windows close box, that Firefox (several) show still running under the Windows Task manager, but not when I use the "File:Exit". Running the current FIrefox version 127.0 (64-bit) under Windows 11.

Hello!

I get this error often when I try to access various websites. This doesn't happen when I use Opera, so I assume the problem is not with the websites.

My OS: Windows 10. My Firefox version: 127.0 (64-bit).

This pops up every few hours. Sometimes it pops up invisible but steals focus from the main window. How can this be disabled?

I tried all methods that have been mentioned everywhere on the Internet, including policy.json, Group Policy on Windows, etc. Nothing disables this nagging yet.

Hi. I feel like this problem has only shown up in the last couple months but for some reason, on firefox, when say watching something on youtube and I go to pause or skip around in the video I'll get this very unpleasant distorted digital noise sound very briefly. I've tried turning off and back on hardware acceleration and some other things but no dice. I can hear the distortion on my onboard sound, my usb headset, and hdmi audio through the graphics card so I don't think its my hardware. This distortion also doesn't happen with say MPC/VLC or watching Youtube via Edge or Chrome.

Hi,

I am running Thunderbird 115.10.1 (Flatpak) on Ubuntu 20.04. (no extensions except birdtray) I have 4 email addresses added to my TB, and I like to see all of them together, therefore I am using Unified Folders. When I am accessing Unified Inbox, TB is very slow and basically frozen until it loads this folder (often a pop-up appears that 'TB is not responding'). it takes between 30-60 seconds to load my emails (either on start-up, or clicking on another folder, then going back to Unified Inbox). Every other folders open almost instantly. I have to admit I have a lot of emails in the Unified Inbox (~20K), however the inbox of my main email has 18K, and accessing that folder separately is instant. So any operation, other than opening Unified Inbox, is quite snappy.

This issue persists since I upgraded to v115, even when I did an OS reinstall (also tried installing apt (v115.11.0)).

I have seen this answer: https://support.mozilla.org/en-US/questions/1428374#question-reply however, nothing changed by resetting the folder.

Very soon after startup it begins to stutter with the spinning beachball of unresponsiveness. At first it will spin, then come back for a few seconds, then spin again. Eventually the whole app is unresponsive.

The troubleshooting steps I see on here all start with "Go to [some location in the menu]". I can't do anything with anything in Thunderbird. I can force it to quit and start it up again, that's about it.

It is also always asking me for the passwords of some of my IMAP accounts. These are big accounts, some folders have several hundred thousand emails. The Inboxes are smaller, maybe a couple hundred in total at the moment. The last configuration I was able to make put it into Unified mode.

The damn thing is that after having been useless like this ever since I installed it, last week it started to work fine. Stayed that way for several days. Eventually that failed, though, and my whole Mac ended up locked up the way the app is, I had to manually power it off.

I don't know if it writes any info about what it's doing to a log file somewhere, I am not having much luck trying to find any information here. Just other people with similar problems but no substantive replies.

Using Thunderbird on an older Mac laptop, running macOS Monterey 12.7.5.

After one of the updates a few months ago, I have started to have trouble with firefox. After a while if I try to open a new tab and type in a link, the tab will try to load forever and I will not be able to open any more as doing another tab and typing a new link will have the same problem. I found that at first I could close the browser and reopen it to have the tab fully load and refresh whatever was already open, but after a bit that started to have an issue too. Most times now if I shut down and relaunch firefox within a few minutes the browser will open with all of the tabs open but they are all blank, with no links filled in, pages loaded, or anything. If I close and reopen after that then it only opens with a "new tab" page and everything that was open is lost. None of the more recent updates for firefox have seemed to fix this issue.

Thank you.

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

Receiving email notifications in Thunderbird but they are not showing in my three different inboxes. Can read them via my mobile phone and if I log into my talktalk webmail? I am currently travelling and logged into a different IPS. There was no problem for the first couple of days. Could this be connected to the issue?

I can't send email from comcast.net account. Outgoing server (SMPT) ERROR. Comcast said problem with mozilla. What should password be for comcast smtp://smtp.comcast.net (smtp://smtp.comcast.net)?

I just updated to version 115.11.1 and now if I delete a message in my unified Inbox, sometimes it deletes and quickly comes back and sometimes it just stays there and I cannot delete again (delete is greyed out). Sometimes it does go into trash but still shows in inbox. In my server settings for that email I have the deleted email set to go to trash for that inbox. Suggestions?

I might give you more info..it seems now if I delete the message either by right clicking or top menu delete, it sends to the trash but stays in the inbox (sometimes it goes away but comes right back). If it stays in the deleted unified folder and I empty that trash folder it comes off the inbox. I have W10..and mail is from Yahoo Cox conversion that was working fine until this update today. Yahoo does seem to be much slower than Cox was so I am trying to be patient and wait but it stays in the inbox until described. The bottom taskbar icon still shows a mail in the inbox too even though it is in trash or even emptied. I have to close TB and go back or say to close window for this new mail icon to clear.

I have also discovered if i send an email from my iphone, eventually it comes into TB but if I delete it on my phone it is gone in TB but is NOT in TB trash but it does eventually show on my iPhone trash...the only way i could see this is to remove Trash from that email account in the unified section and then it shows in the regular trash for that email...seems maybe the unified folders have issues after this update ..this is getting so frustrating...and surprised there has been no response to this help question either..I checked my email here and it is correct..

In box emails on my desktop computer disappear without trace, mail that is in deleted & archive accounts are still there. These emails are still on the server as all these mails, thankfully, are my laptop
