Yesterday I upgraded Thunderbird from version 30 to 31, now while I writing messages the autocomplete for addresses is extremly slow to suggest contacts. If I enter only a letter in the destination field, thunderbird hangs for about twenty seconds and after show me the suggestions. Typing two letters quickly, thunderbird hangs for 13 seconds. typing 3 after 6 seconds All tested even in safe mode I have a local address book with about 9870 contacts (no remote address book) and before the upgrade everything worked fine

Since a few weeks ago, Thunderbird freezes every now and then after sending emails. I tried restarting Thunderbird in Safe Mode with no success. I removed Thunderbird from my computer, moved my profile folder elsewhere, reinstalled Thunderbird from scratch (thus getting a fresh new profile folder) and I get the same problem.

Some people report that changing the signature file to html solves the problem, but I do not even have a signature file on my fresh new Thunderbird install.

I have 3 accounts (2 Google, 1 imaps). I use my own "Local Folder". That's all that is different from a fresh new install.

Hello. I'm getting constant crashes on a new installation of Thunderbird on a new PC. It seems to happen when downloading emails, of which we have tens of thousands, and it seems to crash every few seconds or minutes. I tried reinstalling, and running in safe mode and disabling addons. I tried deleting the account and recreating it. I tried deleting the profile folder and recreating it. We have 4 email accounts on that machine (we have a dozen in total) but as TB seemed to be struggling I deleted all of them and recreated only 1, which made no difference. Apart from that the PC seems to be normal and does not report any errors. We have a dozen other PCs all running Thunderbird with the same accounts and with the same settings, none of which show any problems. The crash reports (I have loads of them) all seem to show EXCEPTION_ACCESS_VIOLATION_READ This is the ID of the most recent one: 4e9ad970-189e-41e9-9399-8db820180222

Thanks in advance for any help.

Thunderbird hangs several times per day. It's always when switching from back to the main window from another (e.g. compose) window. It's usually when trying to open another mail message in my inbox, and often right after sending a message. It hangs and mac gives me the spinning wheel of death. I've tried leaving it for several minutes see if it will recover, but it doesn't. In every case, I have to force-quit and restart. I haven't seemed to have lost any data in the process.

Any suggestions would be welcome.

Changed IMAP to POP. Now I have errors, such as "msgFilterRules...Conflict.dat. Deleted all my message filters, but this message STILL pops up.

I also have popstate-1.dat & popstate-2.dat 2 Junk folders, 2 Outboxes..

I have screwed this up somehow....

I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

delivery format auto-detect does not auto-change to HTML when an image/picture is pasted into email body

problem was present in an early version of TB (sry don't remember which) then was fixed but has reoccurred on 38.4.0 (dunno if it begun at this version, just realized 38.4.0 has this issue again)

if delivery format option set to HTLM then it works (pasted image is sent)

see attached screen shots

Most of the time the new mail sound does not play. I think (not 100% sure), that it does not play when a message is filtered moved.

The sound: - plays when I press the "Play" button in the Options-General. - plays when I send myself an e-mail (it is not filtered). - file is a small 46 KB wav file.

Windows 10 Pro 64 bit. Lots of memory & storage.

On my laptop (121.0 on doze 10) I have no problems but on my desktop Firefox (121.0 on doze 10) started to struggle with Google a few months ago. Sometimes the Google site doesn't load, sometimes it loads but doesn't connect (no auto-complete, no search) and if it does work the result links often don't load when clicked. It's like Google falls asleep and then, when it wakes up, all is fine, until it nods off again. I have followed advice provided, cleared cache, cleared cookies, removed plugins and extensions, reinitiated and reinstalled. Running in safe mode seems to help, as in pages seem to load faster, but sadly does not eliminate the problems. Other browsers on this machine are not affected. No time sync issues.

Any suggestions?

TIA

Win8.1 using Tbird 24.5.0. Download of emails became intermittent in mid-May. As of 6/4, none can be downloaded. No problem sending emails. I have a POP3 account with Earthlink. I started Tbird in safe mode via Help > Restart with ad-ons disabled.

The status bar at the bottom stated that I was connected to pop.earthlink.net. Then it stated that is was 'Downloading message 1 of 116'. After a while with no messages coming in, it stated 'No messages to download'. It never said downloading message 2, so I don't think the messages went somewhere unknown.

This is the situation with my Windows firewall disabled and with my G Data antivirus disabled. I've tried various other things after reading that others are having a similar problem. Earthlink support verifies that I have the right setup. I uninstalled Tbird and reinstalled. I removed the account and added a new one -- and lost my saved emails until I went to my backup. Someone mentioned a ad blocker. I have one on Chrome from Adblock Plus; I don't see how that would affect Thunderbird.

What now? Thanks, Bruce

At every attempt of sending mail via one of my microsoft acounts I receive the following error message

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) smtp-mail.outlook.com is unknown. The server may be incorrectly configured. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I can verify that smtp setting are those outlook suggests. I tried to change the port from 587 to 465 and 25 with no success.

System information OS: Debian jessie kernel version: #1 SMP Debian 3.16.43-2+deb8u5 (2017-09-19) Thunderbird version : 52.3.0 (64-bit)

I receive the same error via windows 8.1 I think with the same version of thunderbird (I will confirm it and repost). So maybe is outlook's or thunderbird's problem unrelated to OS

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

I've just started getting error messages that I need to enter my password to send emails. I've tried that but it still keeps saying unable to connect to the server. This has been happening for about two days now. I've tried updating Thunderbird, restarting Thunderbird and restarting my PC. None of this has worked. I made no changes to my system, software or home network. Any help would be appreciated. Thanks, Dave

I just updated TB from v52.9.1 to v60.3.0. I can open TB & about 30-60 seconds later is crashes. Even when I'm not doing anything with it. Just open it & let it sit there. I have multiple crash report IDs, here are the most recant 2: bp-c5d8aeef-56c9-4530-afe6-a6dc70181107 bp-460ba08c-2084-4bbf-93ad-0167f0181107

I've tried starting TB is safe mode with all add-in disable & it still crashes. By crash, I mean closes instantly & opens the crash reporter dialog. Any help would be greatly appreciated as this is stating to happen to multiple people in our office as TB auto-updates.

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

About 24 hours ago Thunderbird suddenly stopped downloading my emails. I rebooted a few times and still nothing. I went to email web version and my emails were coming in fine there. I read a bunch of articles here and went ahead and deleted my email account within Thunderbird with the intention to add it back in. Then I had password issues and had to call the email provider to reset my password. Now my password is fine, but when I go to add back in my account Thunderbird says it cannot verify the password. I went through several tests with the email provider's support and since I could log in everywhere I needed to with my password, and the only place it will not work is on Thunderbird itself, she concluded that I need to get support from Thunderbird as that is where the problem lies.

Of course there is no support for Thunderbird....and I am so frustrated at this point! I have been using Thunderbird forever! at least ten years or more...and this has never happened before. I really, really really don't want to switch my email client but I cannot seem to get this one to work all of a sudden anymore and if I cannot get it to work I need to find something that does. Can anyone help please?
