Why is it that Firefox can sync links and other setting across all versions, in all locations and yet Thunderbird can't even sync address books, history and filters? My only solution is to only run Thunderbird from a flash drive I have with me all of the time. It's not ideal but it works. Dave out

P.S. It also aggravates me that I have to use OWL with exchange server, which I dislike very strongly!

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

Something happened to my Thunderbird account on 6/15/24. I am not able to send or receive e-mails. I have attached 3 screen shots. One is showing at the bottom right of the screen that it times out and does not bring in any messages. Another shot shows settings for incoming and the other shot is showing settings for outgoing messages. Please help! I have tried to upload images of the screen shots taken and I get this error message. "Error uploading image

Invalid or no image received."

Since December last about every 30 days or so Outlook locks my account. This only happens when I "hit" send on an outgoing message from Thunderbird. A friend has suggested that Outlook sees my outgoing e-mails as spam and when it reaches a critical number Outlook locks my account. Attached is a screenshot of the error message. Has anyone else run into this problem and, if so, is there a solution? Thanks, Ken.

I'm using Thunderbird 115.10.1 and Windows 11 Pro. Thunderbird has suddenly started sending my partner's emails to Trash. We've been emailing fine for years before this. She has not changed anything in her emailing. I've closed and re-opened Thunderbird. Her emails are not marked as Spam and I have marked some of them as 'not junk'. Anyone got any ideas? I can't seem to find reference to other people having this problem.

How do I include a newly made email account so that it will appear in unified folders? I thought that when the new email was added to Thunderbird it would automatically show in Unified Folders but it does not.

Hello

I created an Archive directory within Local Folders, and within that have stored years of emails.

As of yesterday, when clicking on any given sub directory within the Archive, Thunderbird says that there are 0 messages to display.

All of the .sbd and .msf files are present when I browse the Archive structure in my user profile in Windows Explorer.

The problem seems to be that Thunderbird can read and display the directory structure, but cannot display the emails contained within it.

I do not have a backup of the profile directory (yes, I know!).

Can anyone offer a solution that will allow Thunderbird to display messages that seem still be present ?

With thanks in advance

I was using Firefox when suddenly it was no longer there. When I clicked on the icon, it reopened, with all my bookmarks and history, but no tabs! I stupidly shut it down again. The forums all said to just go to History > Restore Previous Session, only there was no such option in History. I tried to do a Windows System Restore to several days ago, but it keeps failing and suggesting that I turn off my anti-virus, which I have. Further reading in the Mozilla forums said to take an old upgrade.jsonlz4-20240618110440 (or whatever date) file from the sessionstore-backups folder and move it into the main profile folder and rename it sessionstore.jsonlz4 (I can no longer use the recovery.jsonlz or previous.jsonlz files because I'd stupidly shut down Firefox after it had loaded with no tabs). I have done this and restarted Firefox, but still get no tabs. That file is huge (22MB) and I've examined its contents and can verify that the tabs are there. So why isn't Firefox reading it when I run it and displaying my tabs? I did see that other people on the forums had this problem but I didn't see a solution. One remote possibility may be that my current version is 127.0.2 (64-bit), while the upgrade.jzonlz... file was clearly generated as a snapshot of when the version was 127.0.1. What can I do to restore my tabs, in light of the fact that I don't have a recovery.jsonlz or previous.jsonlz file with the tabs any more and Windows System Restore is unable to restore my system to several days ago?

I've been using Firefox for a while and there is one file storage site that is always an issue for me. Downloads work but frequently, it stops near the end of the transfer and shows "failed" in the Library window.

Every time, I can click "resume" and it works but it's extremely annoying. If I don't watch the download carefully, I might miss the "failed" message and then the download link times out. There should be a setting to automatically retry a certain number of times.

I've tried multiple add-ons and none of them work.

It must have been one of those nutty "...something I did" things that made a second account identity appear one day. I use a Unified Folders mode exclusively, and the subject account is my primary account (identical to the first Unified listing), but some action on my part made it pop up below as well, just above 'Local Folders.' The only subfolder under this redundant appearance is 'Templates,' which is empty. The unwanted appearance starts out in a blue font, but turns black (as shown below) once the 'Templates' folder is clicked on. Can I get rid of this somehow?

Hello every professional engineer

I knew how to convert the Firefox file sessionstore.jsonlz4 to .json file by using this website https://www.jeffersonscher.com/ffu/scrounger.html

and after editing the resulting .json file

How can I convert it back to .jsonlz4 file to return it to my Firefox profile as it was?

Ladies and Gentlemen, I use Firefox for Android on my Xiaomi Phone. If I enter a search phrase and Press enter I receive the topics found. But if I want to change the search phrase in this same tab it is not working. It Always jumps back to the old one. I have to open a new tab and enter the new search phrase. How can I change this so that it works like on my PC? Thanks Heike

to select two or more messages on the message pane, one method is to hold down the CTRL key and left click on the messages you want to select. This has stopped working on my Thunderbird. When I select a message and then go on to select the next message, the first message I selected is deselected. So I can only select one message for an operation, e.g. "move", "delete", rather than a group of messages.

When I try to forward an email, I get the response: Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The above response was when I tried to forward to another account of mine - both from comcast.net

I have been running Thunderbird for almost seven years now, and these behaviors have persisted since day one on my laptop and desktop computer. First, I have five accounts set up. I am running two add-ons (Provider for Google Calendar, and Quicktext). I am currently running a snap version 115.12.2 of Thunderbird on both machines and they both are running Ubuntu 22.04 LTS. Plenty of RAM and plenty of free disk space.

Here are the two issues...

1. More often than not, when an email comes into one of the inboxes and I am viewing the unified inbox there are two copies of the same email. If I switch back to the actual inbox of the account it only shows the one. This is very aggravating and when you start trying the delete emails from the unified inbox it gets all hosed up and I end up having to go to each individual mailbox to delete the messages.

2. This somewhat relates to issue one... Sometimes when an email is deleted from the unified inbox, a blank record remains like in the image. This shows only one but sometimes there are multiple ones. Of course, if I go to that message's inbox it is not there.

I have tried all the common things like deleting the index files to let the indexes rebuild, comparing folders etc., and again, this has been a persistent problem since day one. Any insight or solution would be greatly appreciated.

Thank you! Mike

Got Thunderbird on 2 machines and both have the same issue. I did try running only one at a time and still I cannot fix it.

On a Yahoo! mail account I deleted a "Draft" folder and it was sent to Trash. If I empty the trash it's gone until I either click Subscribe... and refresh the folder list or reopen TB. Then the folder comes back into Trash. I can't get rid of it.

I logged into the account via their web-based interface and checked my folders. The folder I deleted is indeed no longer there. Not in Trash. Nowhere.

I'm not referencing it in the account either. The option to save drafts is set to the "Drafts" folder, not the "Draft" folder.

I configured the folder properties to be neither subscribed nor offline. I then went to "server settings" and checked "show only subscribed folders" and unchecked "server supports folders that contain sub-folders and messages".

I shut down TB and relaunched it. Folder still comes back. I then shut it down again and deleted any references from the profile's folderTree.json, folderCache.json and the corresponding .msf files. I start TB again, folders still come back.

Then on two AIM accounts I have again phantom "Draft" folders in each. They're unchecked from sync and offline availability. Again I go to "subscribe..." and uncheck them. They don't disappear. I have "show only subscribed folders" checked and still the folders show. I then click Refresh in the subscribe dialog to reload the folder list. They're all checked again.

How do I get rid of these folders? Particularly bewildering is the Yahoo! case where I've explicitly told TB that the account server does not support folders within folders, I don't understand how it can read anything client- or server- side and still reach the conclusion that it needs to restore a "Draft" folder in Trash.

These issues are happening exactly the same on 2 different Windows machines both running TB, affecting the same accounts.
