Thunderbird Community Forum

Please help me log on to Thunderbird in order to open a mailbox file sent to me containing email messages to and from the church I worked for until the June 28, that were in an account they closed before I could archive materials in it.

What I see When I reply to an email written in classic Outlook for Windows, the quoted Outlook text gets a big gap above and below every single line, and its font changes. This happens as soon as Thunderbird processes such a message again, for example when I view my sent reply, reply to my own reply, forward it, or reopen a saved draft. Thunderbird users who receive my replies should see the same gaps.

Why it happens (as far as I can tell) - Outlook writes every line as its own paragraph and relies on a small style rule that says "no extra space between paragraphs". - Since version 151, Thunderbird puts the quoted email's style rules into a protective container (`@scope`) so they cannot change my own text (bug 1967725). - Thunderbird's own safety filter for HTML emails treats this container as a suspicious rule and deletes it, together with everything inside it. The "no extra space" rule is lost, and the gaps appear. - Older versions such as Thunderbird 140 ESR don't understand the container at all and ignore the rules even in the first reply.

In short: one Thunderbird feature adds the container, another Thunderbird feature removes it again.

How to reproduce (no Outlook needed) The attached test message contains two quotes with the same spacing rule: quote A inside the container, quote B without it. In Thunderbird 155.0.1 quote A shows big gaps, while quote B stays tight.

What would help Keep protecting my own text from the quoted styles, but in a form that Thunderbird's own filter and older email programs don't remove, for example by limiting the quoted rules to the quote with an ordinary class name instead of `@scope`.

Technical pointers - Filter: pref `mail.html_sanitize.drop_conditional_css` (default true); `NoConditionalRules` in `stylesheet.rs` rejects `CssRule::Scope`. - Container: `QuoteSanitizer.sys.mjs` (Phase 2), called from `MsgComposeCommands.js`. - Tested with Thunderbird 155.0.1 on Windows 11.

Installed Thunderbird in August 26. Successfully added Outlook and Gmail accounts (send and receive)

On a roll I then tried to migrate from Plusnet to Greenby. Can successfully receive emails via IMAP.plus.net server. But could not send mails from Greenby (other accounts still OK)

Traced problem via forum query 31???? to inability to create a new SMTP server for outbound mail. After entering all data in the outbound server there is no response whatsoever to clicking add button (ie no error messages or servers added to SMTP list)

Then tried to delete the partially active Greenby account via clicking delete button in account setting window. No response. Account still present.

Does anyone have any suggestions to solve this before I try the doomsday action of deleting and reinstalling Thunderbird.

TIA Phil

I've had AOL for an Email provider for several years now. I rarely went to the website to check my Email cause Thunderbird was linked to it. But today, AOL seems to be turning off my Thunderbird (I can't send or receive Email at the moment). It's like malware with the continuous popups making me log in to AOL to use Thunderbird but then ending up on some Yahoo Oops screen. I've been using Thunderbird since before I transitioned to AOL after moving.

It's been working fine up until today. When I do anything on Thunderbird, the annoying popup screens appear wanting me to log in. Any ideas? Have I been hacked?

Hello people, I've just upgraded my Thinderbird because my inbox didn't load on opening the programme. I guess I have made a huge mistake somewhere in the process, because my whole archive has disappeared. I very much hope it still exists somewhere and that I will be able to restore it with your help. Thanking you in advance, Nele Ysebaert, Amsterdam

Hi, hoping someone could help as I am struggling to get my information back. I am using Ubuntu Cinnamon.

Thunderbird crashed last night, wouldn't work, tried safe mode. Nothing fixed it. It hung when opening up and after 30 seconds said force quit. So I was forced to reinstall. I did a manual backup but not using the inbuilt tool as I couldn't get into Thunderbird. I just copied the data from username/.thunderbird

After spending a long time uninstalling. Because it reached 78% and then crashed on uninstall. Eventually after reading various pages on the internet I managed to reinstall from the Ubuntu software manager using the latest snap version. (Which I am not sure was what was actually installed previously).

However having used thunderbird for nearly 20 years or so. I have a username/.thunderbird folder. And when I moved to this platform, I have a snap/thunderbird/common/.thunderbird folder.

I installed this new distro 2 years ago, and remember having issues getting my data into the system under Snap. But eventually got it to work somehow back then.

However since reinstalling I cannot see the last 2 years of emails, archives or data. It has launched into a 2 year old profile. I appear to have lost most of the emails from the archive folders (but kept the folders) removed all of the personal folders but then dumped all those emails into my inbox. Giving me 6500 emails that were in various personal folders. (I don't get 6500 emails in a year so don't know what has happened.) It has even changed all of the new dates to the US format, so nothing makes any sense.

I now have 2 Thunderbird profiles, over 12GB in size. And have apparently lost 2 years of my life. But reading support pages, suggests I should be okay because thunderbird doesn't delete data when you reinstall?

I have looked through various other threads which talk about pointing it at the profiles and mail boxes, however nothing works.

Any help much needed.

if I start Tunderbird I get the message "https://caldav.web.de verlangt einen Benutzernamen und ein Passwort". I have stored the password many times but it appears any time I start Thunderbird

Hello. I have several saved search folders in Thunderbird. These are all tax related. The searches are run against my local archived emails and are mostly searches against specific received dates (my tax year). I have found several of the searches are duplicating the results of the search. When I check the folders I am searching within, there are no duplicate emails. I was wondering if anybody else has run in to this problem. Deleting the searches and starting over does not fix the problem.

My TB installation got corrupted due to a hardware/disk issue. On restoring it from backup TB keeps trying to download all messages again. I know this is something to do with the popstate.dat file but I can't seem to stop it. What do I need to do?

Also, I had never noticed this before (because I never looked at the TB file system) but TB created multiple folders for the email account.pop.mail.yahoo-1.com up to pop.mail.yaho-4.com. Why does it do this and is there a way to get back to just one file? Is this something to do with TB crashing or what?

Is it using all of these files or just the latest and how do I know? All of these folders have a popstat.dat file and one has multiple following the popstat-1.dat etc.

I've no idea how to recover from this. Any help would be much appreciated.

Thunderbird normally displays the number of messages in a folder, near the top of the screen above the list of messages. But somehow, clicking around, I lost that display of the message count and cannot get it back. Wondering if anyone knows how to get that number back, get it show up near the top of the screen. I'm using version 156.0.

I use Thunderbird all the time as my email on a desktop PC.

For several emails, especially some from yesterday the Correspondent and the subject have  ?crossed?

For example: an email looked from the Correspondent list as if sent from my energy provider but the message was from a Garden Centre. It's not a one-off; another message looked like from a magazine but was a receipt for a purchase. They were not consecutive so it's not as if the list has 'slipped' by one or two. I think it's happened before but not as worrysome.

Is there a reason or solution please?

I'm now scared to delete unwanted emails without time consuming checking each one in detail.

Thank you for any advice/support/suggestions

I have recently closed my yahoo mail account, removed all traces from Thunderbird, but when I start Thunderbird, after a few seconds, I get a Yahoo sign in screen over the top of Thunderbird

I upgraded my Fedora nad I think that Thunderbird 149 came with that upgrade. I cannot send mails. Ctrl+enter has no reaction. Downgraded to 148 and everyhing is fine. |<

The sorting of the Recent Destinations menu has changed and is now no longer usable. It is not sorted by most recent or any other obvious order. It now takes me more time to scan through the list to find what I want when it used to be a very useful/quick tool. Anyone else notice this new issue? Thanks!

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

Hey Guys,

My Left click to open links from my emails has stopped working. I have to right click and select Open Link. I have tried everything, tried going through some of the config editor options i saw people mention for this issue and its all set to True already. There is no data besides PDF under the settings / attachments section. So cant change anything there. I tried a new profile, no go. I did a full uninstall and delete profile and started again, still same issue.

Left click to open links for everything else on my computer like firefox etc. Just cant open links through thunderbird. It used to work, it seems to have stopped around the same time as the latest update but i cant be sure about that. Only stopped working the last few days,

I am running Thunderbird 140.9.1esr on openSUSE Tumbleweed.

For a long time now, Thunderbird often runs at high CPU (80-100% of one core), for several minutes at a time (5-10 minutes). This seems to happen many times every day, with no apparent cause from my end. (I just got back from Lunch, and the fan on my laptop was going crazy because of the high CPU.)

What can we do to identify and fix this issue?

Couple months back had to restore computer. Wouldn't let me add my POP gmail account, said had to use IMAP. POP was no longer accepted or something to that effect. So I got IMAP set up. (Of course, I did save my old POP folder with some messages in it.) Ever since setting up the IMAP folder I only get maybe 30 messages each morning. Never more. Which is no way right. I've googled and tweeked the synchronization/storage settings and the server settings. Nothing works. I'll spend hours googling suggestions and trying them, then get frustrated and move on. Then a week or so later I go thru it all again. Nothing changes!! Still only get the very few emails each morning. About 30 or so minutes after the initial download of messages, I'll get a pop up saying imap connection lost. This is SO frustrating. I have no idea what to try next. I never had this kind of issue with any of my POP accounts. Any suggestions? I've probably already tried them but will certainly give it another try. Thanks! Lynn
