Thunderbird Community Forum

I run Thunderbird on a PC, and, to free up space on Drive C:, I have moved the contents of the folder Thunderbird in Appdata to Drive D:. I then changed my Server Settings, in Thunderbird, from C: to D:, and note that any new mail is indeed now appearing there along with those already transferred. This move could save me a valuable 6 gig of space, and more in the future, however, I am unable to remove that original Thunderbird folder entirely, notably I am unable to remove the contents of the Profiles folder, as it is still linked to the application. Notably with cookies.sqlite, cookies.sqlite-shm, store.json, mozlz4, aborted-session-ping and many others, which I note some have continued to be updated. I have been unable to find any other settings in Thunderbird referring to Drive C:, other than those in Server Settings.

I could presume that if I installed another version of Thunderbird on Drive D: and maybe moved those existing contents of the Thunderbird folder on C: onto Drive D:, and made those numerous settings changes to the App it could work. But I ask is there an easier way to complete this move? How can I complete this transition of Thunderbird from Drive C: to Drive D:?

Hi Folks,

As I said above, I just updated to Thunderbird version 128.2.1esr (64-bit) and seem to have lost a couple of functions, in particular the ability to make a new Tab, and the use of an extremely handy Add-on, Shrunked Image Resizer. I have Mac OS 12.7.6 and I noticed in the release notes for 128.2.1esr (64-bit) that this latest version's System Requirements are MacOS 10.15 or later. Does that mean that I should not have downloaded the latest version, and if so, how can I revert to an earlier version of TB that will allow me to use Tabs and Shrunked Image Resizer? I thought that Thunderbird was capable of recognizing which version of Mac OS I have and thus would not suggest I update to the latest version of TB if it won't work as it did with an earlier version of TB. I would be very grateful if you could suggest a solution to my problem.

Thanks, Chris O'Brien

Hi

I recently updated to 128.2.1 esr and my message filters are not working. When I open "Tools" > "Message Filters" the filter list is empty but when I open the msgFilterRules.dat file on my profile the message filters are there. (I made lot's of them.)

Hello. I have installed Thunderbird on my MacBook Air M3, unfortunately indexing does not work. When I open the Activity Monitor, ‘Indexing Messages’ appears in the list, but after 2 hours it is still at zero, the first few were made in the first millisecond. What can I do? Thank you for your answer

Hi. Is there a way to add travel time to an appointment just like you can do in google or apple calendar? It’s a great feature. When I add an adres to my appointment Apple calendar will automatically add the travel time by car from my home to the destination. I miss that feature in Thunderbird.

After the most recent update, I now have to double click on the message to read it when it used to show up in the current message pane. I found posts referring to tools->options->display but there is no such path in my Thunderbird. Using Windows 10 pro version 128.2.1esr (64-bit)

Any fixes to offer?

I've asked this question before. Sorry but I cannot locate my question on this forum. I have several "sub" address books for special interests: warnings, comedy, politics, etc. In the past I've been able to right click one of these sub-headings and I got a list of actions, including "copy to BCC". That enabled me to send a message or (usually) forward a message to the recipients in that subcategory without sharing their email address with each other. I no longer can get that option on right click. Is there any way I can use that option again? Many thanks, and apologies for my ignorance about bringing up my original question and having to start a new one. Jack

I suffered a computer crash and in the process of recovery made some mistakes.

I would like to recover old messages and the calendar. Unfortunately, there are multiple profiles and (I didn't create them) I'm not sure which one to use.

I am uploading various images of the profile folders. If additional info is needed, I am willing to upload.

Ultimately, I want to combine the older messages with more recent msgs.

Thanx in advance,

Mike-a

I solved this problem already by finding this thread previously :

https://support.mozilla.org/bm/questions/1399586

If your thunderbird window shrinks when being displayed on your internal laptop monitor but expands when displayed on an external monitor (or vice versa) it is because if the value for

layout.css.devPixelsPerPx (Edit -> Settings -> General -> (all the way down) Config Editor -> (search for) layout.css.devPixelsPerPx)

is set to a positive value. It seems like the value has a reverse effect in between internal and external monitors (shrink one and expands one).

To fix this issue, set the value for layout.css.devPixelsPerPx to -1

I am posting this question to display this solution to the public if anyone else experiences a similar issue.

When I switched my computer on this morning, Thunderbird refused to dowload new emails. Nothing I have tried solves the problem. A message in Crash Reports says:

"Shutdown hanging at step XPCOMShutdownThreads. Something is blocking the main-thread".

My copy of Thunderbird is up-to-date and accesses two accounts (Gmail and my university account (IMAP)). New emails are missing from both.

Any advice on how to solve this problem would be appreciated.

Thank you,

I get notification of incoming emails but they never show up in INBOX -- or over a long delay. This happened once before having to do with off/online. I have no idea how this happens. Again, as before, I need help. Thanks, Eddie

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

I read that I now need a secure mail key so I can access my emails with third party app Thunderbird. I have created a secure mail key at att.com which is part of Yahoo. My email app is att.yahoo.com. I was told the passwords for Thunderbird would be within the profile under the Profile Folder but I cannot find them there. All I want to do is update my password within the Profile Folder and it seems like it would easier to break into Fort Knox.

Our email accounts are attached to our host domain name. We are going to be changing the host domain location from a smaller local provider to Spectrum Internet to service. The email addresses XXX@xxx.com 'will not change, only the server host location. As a backup, we are moving all existing emails located in subfolders under the email accounts to the LOCAL folder (creating new "trees" there) so they are in a permanent location to be unaffected by the server change. From my knowledge... we will not create new email accounts in Thunderbird .... only change the server location, ports, etc for that specific email. I want to confirm with others that this should be the plan?

Hi, I have configured 2 accounts for E2EE using OpenPGP. I can send signed emails &/or encrypted messages between the 2 accounts. However, if I send a "normal" message i.e. no signing & no encryption selected, it arrives as not signed (correct), but encrypted according to the "Show message security" icon. If I send a normal message to an account that has no known encryption setup, then the message arrives and the "Show message security" button is missing (correctly).

Any ideas why this is happening? Thanks for your help.

Thanks for listening: Last week, Thunderbird began returning this message with each attempt to send mail: An error occurred while sending mail. The mail server responded: <tedcomo@chartertn.net> sender rejected. Please verify that your email address is correct in your account settings and try again. I have no problem receiving mail. At the same time, my wife began having the same problem on her laptop, which tells me either Charter, or Mozilla, changed something. I started with Charter. They told me to rename both servers to mobile.charter.net (outgoing mail was formerly smpt.charter.net. No effect. They then had me log into Spectrum and send a test mail directly from my account. It went through OK and they said the problem had to be on Mozilla's end. Any suggestions?
