After the most recent update, 78.4.0, I cannot receive emails. I can send emails. Also the folder icons changed from yellow to white. Erols.com (RCN) is my email host. I can still receive emails on my phone and through mail2web.com. I have tried turning off firewalls, both Webroot and the native one in Windows 10. I have tried uninstalling and reinstalling both latest version and an earlier version. I checked to make sure the proper password was still saved. When I hit the Get Messages button, there is a "Connected to pop.rcn.com..." in the bottom pane where the "unread" and "total" are listed. It just vanishes after a bit. Anybody got a cure?

Hi;

Have Thunderbird v78.0.1 (32bit). Tried importing items, (EML format), from Windows Live Mail v2011 Build 15.4.

Used Thunderbird's built in Import Tool. Kept getting: "Can't find other e-mail programs" even though Live Mail is still installed.

Downloaded importexporttools_ng-4.1.0-tb.xpi AND importexporttools-3.3.2-sm+tb(1).xpi. Both show "Not for v78.0.1".

Would someone kindly point me in the right direction so that I can Import Windows Live Mail Accounts & E-Mails into Thunderbird v78.0.1 (32bit)?

Thank You.

Andy

Thunderbird 78.5.1 On computer A, probably since one of the latest updates TB is not able anymore to connect to the server, I only get the error message "connection to server xxx failed"

Activity manager shows no messages at all Server xxx is on my network, connection is not blocked TB profile seems to be ok : when using the same profile on computer B, everything is working fine

  • creating new account (same data as existing account) on new profile on computer A is not possible : message "Unable to log in at server. Probably wrong configuration, username or password"
  • however using exactly same procedure and data on computer B, it is working !

So, creating a new account on a new profile is not possible Disabling firewall and AV : no change TB safe mode : no change Reinstalling and uninstalling/installing TB again : no change Windows safe mode with Networking : no change TB config:security.tls settings are identical on computer A and B I changed TB config:security.tls settings : .version.min to 2, 1 and 0 : no change

and .enable_post_handshake_auth to true : no change
and .version.enable-deprecated = true : no change
(all after restarting TB)

Changing TB Server Security settings : no change

I deleted the stored passwords, but after restarting TB is NOT asking for the pw's meaning TB is even NOT trying to connect to the server ?

(error messages are translated from Dutch, so possibly not identical to English ones)

see also https://support.cdn.mozilla.net/en-US/questions/1304493 https://support.mozilla.org/en-US/questions/1269090?page=2 https://support.mozilla.org/nl/questions/1313268

I think I tried almost everything to solve the problem. It seems the problem is on the computer/TB installation, but where ? Can someone tell me how to proceed further ?

How do I disable the ANNOYING message box I get every time I want to send a message to the trash folder. Thunderbird keeps asking me if I want the message deleted to save disk space. This just started in the past week. I want my deleted messages to go to the trash folder and I will manage that folder. I can't seem to find anything in settings that lets me disable this option.

I have just now set up the new version of Thunderbird. I must have made some mistake in setting up my new account. I can enter the "to" from my address book but cannot figure out how to send "cc" to multiple addresses. I can send with one cc recipient but can't figure out how to include multiple cc recipients.

I love Thunderbird - it is a great email system.

As you can guess from such a fundamental question, I am quite elderly and not a teckie.

Any chance that one of the youngsters among your volunteers can help an old man out?

Thunderbird Inserting Unnecessary Line Breaks

After an extraordinary amount of testing, I can conclude that Thunderbird is placing linebreaks inappropriately in emails sent from Thunderbird.

In other forum posts, I saw these described as "soft" line breaks that email clients could ignore, but in my testing, Gmail, Yahoo, Outlook/Office 365 all display these false line breaks (in both webmail and mobile apps). In fact, the only email clients that did not display these false line breaks were Outlook 2016 (Windows 10) and Thunderbird (Windows/macOS).

The issue is that Thunderbird is inserting these line breaks where the line changes in the view of the composer. This is an arbitrary line that really serves no obvious purpose, given the thousands of possible variations in screen sizes on mobile or desktop?

Toggling between sending in HTML or plain text seems to not have an impact in resolving this issue, and neither does switching between "Paragraph" or "Body Text" modes.

Example images are attached of how this looks.

Any hope for a resolution on this issue? (via Extension or correction by the developers?)

After installing new version of Thunderbird I am getting completely blank Thunderbird screen. This occur few times before while I user versions lower than 68, but after restarting it was OK. After update to version 78.4.0, first starting is OK, but after that I am getting completely blank screen. Only thing that works is: click at top left corner and only drop down File menu appear, move mouse to place where Help menu should be and it appear, then click on Restart with Add-ons Disabled and restart in Safe mode. Safe mode is working OK. I have tried uninstalling all Add-ons and start normally but I am getting blank screen. I am using Thunderbird Portable. I have copied Thunderbird Portable completely to other computer, updated it to 78.4.0 version, it was OK, and copied it back to my computer. That worked. But when I updated to 78.4.1 I got blank screen again. I am using Windows 10 running on Parallels virtual machine on MacBook Pro, anti virus is ESET. I managed to revert to previous state by using Parallels snapshots, but I would like to solve this issue. Another person in my company has this problem, also running on Parallels.

Version 68.12.1 on Windows 10 I know the exact subject of the email, I have sent it to myself a month ago. I type "upgrade m1" with quote marks on the top global search bar and I get all kind of junk with the word "upgrade" that are mainly spams. If I scroll back manually I can locate the email with the same subject in my inbox. I have rebuilt the search cache already.

Any suggestion?

I'm trying to import contacts from Windows Live Mail. When I use the .csv method it imports everything but only shows a human silhouette on each line with NO text. When I try the .vcf method, WLM won't let me export to anything but a folder, and the import process doesn't recognize the folder as a whole and will only import one address at a time if I open the folder. How do I do this???

I've used Thunderbird for years. After the most recent update in late July 2020 (78.0.1), Thunderbird no longer works. It will not download new mail. It does connect to the IMAP server but then gets to "checking mail server capabilities" and hangs with the spinning circle indefinitely.

I have not done anything to Thunderbird, I just let it install the update. I did not install updates to any other program on my PC. I'm running Windows 10 on a laptop that is about 4 months old. Thunderbird worked absolutely fine before the 78 update.

I am not experiencing any connection issues or problems with any other running programs.

I have tried the following fixes already: 1. Checking my account configuration and confirming it is correct with my email provider. I have the correct ports listed and correct server names. 2. Changing the timeout setting from 100 to 2000. 3. I am able to access my email on my provider's Web interface so this isn't a password issue. There is no CAPTCHA required either. 4. I checked my anti-virus/anti-malware program (Kapersky). Thunderbird and Mozilla are both listed in the "allowed apps" list. I tried removing them both and re-adding, as well as searching for other variations of Mozilla/Thunderbird to add. I also tried Kapersky's "refresh" function. 5. I tried restarting my computer. 6. I tried rebooting my wireless Internet connection. 7. I tried using Thunderbird's "start in safe mode with apps disabled" function. 8. I tried re-installing 78. 9. I tried clearing caches and cleaning with CC Cleaner.

Nothing has worked. Something in the 78.0.1 update has messed things up. Thank you for looking into this.

Thunderbird Email Problem After the last update to Ver# 78.4.0 my Thunderbird email software is not performing properly. I believe this occurred on October 28, 2020.

What works: • I have no problem loading Thunderbird • I am receiving emails and the filters I have created are working fine, placing emails in the appropriate places. • The last sent email was on 10/19/20

What is not working: • I cannot access nor open my Addressbook, both Personal and History. • I cannot send emails. The Send button is not activated. • I cannot reply to existing emails. I have clicked on reply, typed the message I wished to add and again, Send is not an option available. I have tried many things on your Support site, as well as other help posts on the Internet but to no avail. I have looked at my Profile and all appears to be fine but Thunderbird does not appear to be looking at it for preparation of outgoing emails. I did try creating a new Addressbook as someone noted and it I did see it in my Profile but I cannot save nor retrieve any email addresses I try to put in it. Help please.

Hi everybody,

I was just w riting to ask as I can only seem to increase the font of the e-mail written text, but really the interface size is absolutely ridiculously small and is there any way I can enlarge this (without reducing the resolution of my monitor which is not really a solutuion)

Not everyone has the best eyesight for this kind of thng and I find thunderbird the best mail and calander client but at least on windows or in browser-mail I can CTRL+ to zoom in and read, it's at the stage where I might have to use the windows magnifying tool just to see t hings like "inbox" "spam" and my list of emails' titles.

Please tell me there exists an option to make all this larger like interface size, I mean come on almost every modern software has an option bar slider to increase these things

Cheers
