Thunderbird Community Forum

When I use Shift-ArrowKeys (or Shift-MouseClicks) to select multiple messages, as soon as I select the second message in the group, the Preview Pane switches from message preview mode, to some kind of an "aggregate text-only few-lines-of-peek" mode (don't know how better to describe it).

In this mode, it shows a few text-only lines of each message in the selection, which is usually of no value whatsoever because most eMails are HTM and the text shown is meaningless. I can't see the whole eMail as I select them in a group (usually to delete the group).

(I've attached a screen shot to show what I mean)

I want Thunderbird to stop doing that, and just show me a true preview of each message as I select it for addition to the selection group, so that I can read it and be sure I want it in the group, just like it does when I select a single message instead of multiple ones.

Can I get Thunderbird to show me the correct and full preview somehow?

I have spent the last TWO HOURS trying to find an answer to what should be a simple problem, and it seems not to exist!

I need to find out WHERE Firebird lists my email account PASSWORD.

I do NOT want to reset my password.

I simple need to know WHAT my password is, and since I set up the account [actually a few accounts] several years ago, my notes are evidently null and void, because none of those passwords seem to work.

My email is through verizon.net, which is one of the problems because they gave all of their email coltrol to AOL, which thouroughly sucks, and they seem not to have anyone who speaks fluent English who can assist me in FINDING the current password!

If ANYONE can help, it would be most greatly appreciated!!

When setting up for authorization in sending email from Windows Live account, the Oauth2 option (as seen in the guide) is not available to select ? See Picture

Hello,

I can't receive new emails on my Thunderbird account because every time I try to refresh my inbox, I get this message:

‘An error has occurred while saving your messages. Make sure that the file system gives you write rights and that you have enough free disk space to copy the inbox’.

No problem with webmail.

We have another computer in the office connected to Thunderbird that receives all our emails. All the settings are the same, except that we haven't updated Thundebird.

We use a POP system.

Thank you for your feedback!

Having just re-installed Thunderbird I receive the following error message when trying to set up my gmail account, which had been working fine before

400. 

That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

The password is correct as I can login from my browser and I have easily setup my other email accounts - not gmail. Also have re-started PC and Thunderbird.

Help please, regards, Haydn

Message filters not working after transfer to new windows device. (Apologies for long report below). Problem is similar to that reported and still unsolved here: https://support.mozilla.org/en-US/questions/1391209

All old messages automatically accessed under IMAP protocol sit within correct email folder on new device.

Message filters rules successfully located on old device, copied and placed in corresponding windows folder on new device. Email folder structure looks identical on both devices.

New messages sit in inbox on new device, without being filtered. Instead error messages appear, repeatedly.

"The folder 'xxxx' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

The folder 'yyyy' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

If same new messages are accessed on old device, they later appear in correct folder on new device, and no longer sit in inbox

How to make email folder structure on new device visible to filter rules there ? This is necessary for filtered email to work successfully on new device, without requiring old device to be operational - it will be taken out of service in near future.

I tried to do an import of a backup profile that was very large, greater than 3 GB. System says this file is too big to recover. Error console is as follows:

Hi. I have created 2 subfolders in "Drafts", which ALSO turned into draft folders:

• The folder icons switched from the standard folder icon to the "Drafts" icon.
• The right-click context menu is reduced (just like for other special folders), e.g. the "delete" command is missing.

So how can I delete this misbehaving folder now ?

I doublechecked in my account manager and via config editor that the subfolder are NOT used as DRAFTS folder for any of my (POP3) accounts.

Thank you so much.

Hi Everyone,

I have Thunderbird installed on two computers. When I receive messages that are in plain text, on one computer they are being displayed in a modified format with whitespace and carriage returns removed. On the second computer the messages are not being reformatted.

What setting do I need to change so that plain text messages are not automatically reformatted?

The trouble is that these messages are written with the contents displayed out in a nice table format, and when they are reformatted it makes them very hard to read.

I have tried searching for the answer myself, but I haven't been able to find anything that directly relates to this question.

Thanks, Ian

Hi. Same question as in https://support.mozilla.org/en-US/questions/1226211  : How can I customize the TB's main menu ?

I would like to remove menu items, which I never use:

• for simplicity
• to avoid accidental deletion (e.g. "delete folder", "delete message", "delete mail marked as junk in folder", etc.)

many thanks!

Is there some way that I can nullify the format changes in the v128.x message list, compared to v115.x, so that my UserChrome.css tweaks that are functioning well in v115.x are not broken? Perhaps there are some new Config flags that might be set? I hate to have to redo a bunch of carefully calibrated work.

Sample of v115.15.0 message list included; I uninstalled v128, so I can't easily show a sample of that.

Windows 10 thunderbird 91.13.1 (I know ... out of date, but I tried a newer version last year and hated it.) My special address book sub categories don't work as they used to. I used to be able to right click on one of them and I got a choice to add all the entries in to a BCC field. This was great for forwarding things to a list of people with a common interest, but without sharing their addresses with all of the other recipients. It just quit doing this. If there is no easy solution, I guess I'll have to man up and upgrade! Many thanks for your volunteer work! Jack

Please help me. I've been with Thunderbird for many years and now I have nothing but problems. I've attempted to change settings and I'm thinking that possibly I've screwed it all up. I've changed the passwords through Comcast a few times but it seems to also be screwed up. I've been with Thunderbird for a long time and donated 3 times this past year. Now I have constant problems signing in with the same old password so I've contacted Comcast to change the passwords. Is there anywhere on Thunderbird where I can check to see what passwords are still listed for me? I have 4 email addresses. SillySam, LatonHigh, Kissincousin and TahoeDocTom all with Comcast.net I'm desperate to get back online with my emails.

A recent Thunderbird update (auto update) must've been interrupted, because I keep getting a "Reboot your computer to complete the update" message. I have rebooted many times with no change. I tried to uninstall Thunderbird, but get the same message. I also tried to reinstall it, but no change. The Thunderbird icon has also changed to a computer with a disk in the front. Any ideas??

I supply software that uses TB to send emails with an attachment (via MAPI - an invoice) I have a number of customers for whom this has stopped working. I tested all of these with the usual fixes. The app has full access to the folder containing the file. The app is set as administrator and is inside the firewall. I have set default mail app to TB. TB is set to check as default on startup. Yet windows keeps saying we need to define a default email client. One customer solved the problem by buying a new PC. I have another customer who has this problem on a new PC. There may be a common denominator in Microsoft Office which on loaded onto the PC's. If that is the problem then that is Microsoft denying access to TB? Has anyone had this problem and can suggest a fix I would be grateful.

I have Thunderbird up and running on one of my Oracle Linux Virtual Machines.

I enabled the FiltaQuilla extension, because I want to save message attachments automatically to a local filesystem, and then run a backend script against those saved attachments.

Everything appears to be configured correctly.

The email filter is working sporadically. Sometimes it works, and sometimes it doesn't. It is not consistent.

It does not seem to work immediately, and it does not seem to work when I try to manually run it.

But, if I leave my computer for a little while and come back, the saved files will magically appear, "somehow", but only sporadically.

Even though the filters appear to be enabled, they are not being kicked off when the new messages arrive.

I currently have 3 options in place, in the "Filter Rules" window:

"Manually Run", "Getting New Mail: Filter before Junk Classification" and "Periodically, every 10 minutes".

I wish there was an option to "Run with each new message received".

I set a "Subject Contains" filter, and that is my only filter.

Then I tried both "Detach Attachments To" and "Save Attachments To", but neither of them seems to be working properly.

For a brief few minutes, I attempted to combine "Move message to folder", but it moves the message immediately, before the first filter has a chance to save it to the local filesystem.

When you have different actions in mind, there MUST be a way to prioritize each action, so that the first option MUST complete successfully, before attempting to complete the second, and subsequent actions.

In my case, I need to save the attachments to the local machine, before removing or moving the message.

So, if action number one completes successfully, it goes on to complete the second action.

If action number one fails, it stops all processing of future steps, so that the failure can be debugged.

I really need a solution to the saving of attachments to local filesystems (This is in Linux).

My Thunderbird stopped downloading new email messages on August 22 (but is still able to send). Microsoft says that Thunderbird is not comptatible with Windows 10, but it worked fine before the update. Is there now a compatibility issue?

Using TB 115.15. When I move a large number of messages (200 or so) to a sub folder the move goes fast until it gets toward the end, then it locks up until it finishes a few minutes later. When I tried to move over one thousand messages at one time, I let it run overnight, some messages moved, some only moved a date header of some earlier time (all the same time) and all messages were left intact in the original directory. After moving the messages a few at a time, I had to manually delete the duplicate messages in the sub folder. What is the maximum number of messages Thunderbird will move at one time.
