Quick Filter does not return correct results in Unified Inbox (Thunderbird 140.12.0 ESR)

I'm using Thunderbird **140.12.0 ESR (aarch64)** and believe I've found an issue with the Quick Filter when searching the **Unified Inbox**.

• • Steps to reproduce:**

1. Open the **Unified Inbox**. 2. Open the Quick Filter bar. 3. Enter a search term (e.g. "maddy").

• • Observed behaviour in the Unified Inbox:**

• With no "Filter messages by" options selected, entering a search term does not filter the message list.
• Selecting **Sender**, **Recipients** and **Subject** still does not return the expected email.
• Selecting **Body** changes the results after a delay, but the expected email is still **not** returned.

If I open the **actual Inbox** containing that same email and repeat the search:

• The expected email is found using **Sender**, **Recipients** and **Subject**.
• When **Body** is selected, the search takes longer and eventually returns additional matching messages, including the expected email.

This behaviour is reproducible with multiple search terms and suggests that the Quick Filter does not search the **Unified Inbox (virtual folder)** correctly, even though the same search works in the underlying physical folder.

Could you please confirm whether this is a known issue or a bug?

After upgrading from Mint 21.3 to 22.3, Thunderbird no longer offers me the option of setting email alerts for events. Details: - I have Provider for Google Calendar installed - I've tried adding my calendar as "Google calendar" and "On the network" but neither offers email alerts. (On the network works better for responding to invitations.) My current work-around is to go to the google calendar app on my phone and set an email alert after creating the event in Thunderbird. That works but is a pain. This worked before. I suspect it's more a configuration issue and less a Mint version issue.

Hello dear forum Here are the details: Account type: Microsoft Exchange (via OWL) Antivirus software and firewall used: Bitdefender I have the following problem: I copied the mbox files from the active account (profile) to Local Folders (as described in some forums), both with and without *.msf files (seems this makes no difference to the problem). Then I start Thunderbird, and all folders and subfolders appear in Local Folders. However, when I go into one of these copied folders or subfolders, it only displays a single email. The copied folder is the same size as the original, but no other emails are displayed, and this is repeated in every subfolder. I employed the repair function with no result. The import/export tool NG only copies half of the emails. The total is 4.25 GB. I can only copy the emails manually via copy/paste, but this is very error-prone and takes a very long time. Has anyone had experience copying mbox files and managed to do it successfully? I would be very grateful for any advice.

Got a new macbook, did migration from the old to the new. Thunderbird failed to migrate. The icon on the desktop did, but it is not listed in the application list. Both are running the same software version, Tahoe 26.5.2. Talked to Apple, they tried to help, but in the end, they answered that it wasn't their software, so contact Thunderbird. Thoughts???

I keep email tabs open if I am going to have to reference the email for some reason -- shipping product tracking emails, legal documents, threads of conversations that are ongoing. Every so often, Thunderbird decides to open with all of the tabs blank. It's unrecoverable, and I have to search each of the tabs I really needed to open up again after spending time X ing the blank ones.

I've been filing about this bug for years now. Mostly what I get is a bored moderator/mentor telling me why that isn't a priority, and how I should change my emailing behavior. I just lost track of several legal documents and am anticipating working for hours to get them back on top.

I'm very sick of it.

I have a particular need to periodically run junk mail filters on a folder in Local Folders that I know will contain mostly junk mail. According to a search engine, the command to do filtering on particular folders should come up in a junk mail tab when you right click on a folder and look under properties. When I right click on a folder, however, I never see a junk mail tab under properties or anywhere else. Where to I find the command to do junk mail filtering on a specific folder? Greatly appreciate any assistance.

Downloading messages is now noticeably slower on an older desktop if the 'Inbox' folder is selected/focus. If focus is changed to a different folder (i.e. 'Sent') the message downloads become blazing fast.

Deleting messages seems slower as well and I think it is related. May involve inserting/deleting entries in the grid.

End user here, with Thunderbird for years, now on several machines that I use. Keep getting the warning window about "ESR" change. I have no wish to re-install Thunderbird, on each machine, nor to go beyond the normal updates. Can't tell which "channel" I need to choose. Unwilling to just guess. Could re-install on all five machines, if that's truly necessary. Hope not. An explanation of the simplest way to dispose of this issue, is the help I'm looking for. I think I'm currently set to the lower case address. And arranged such that each machine updates to the current content.

I got an eMail notification about an upcoming update for Thunderbird snap/flatpak configs, but I don't see any entry for Thunderbird in my "~/.var/app/" directory. There is an entry for Firefox, but nothing for Thunderbird. Yet Thunderbird still updates regularly and successfully.

What should I do, in order to conform to the eMail notification instructions?

Running the command "snap info thunderbird" returns the following --

For five or so days, when I go to send an email on my iMac, I get a message saying SMTP server won't send it. If I go to webmail, it sends, and if I use my iPhone it sends. Rogers/shaw has walked me through testing and nothing is wrong their end. Is anyone else having this problem?

Full errror: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

Operating system Windows 10. I have Thunderbird installed on three computers. Two on Windows 10 and one on Windows 11. I have two accounts Helen and Kevin. I have no problems with my Kevin account on the there computers. The error only occures with my Helen account and only on the Windows 10 computers. Not the Windows 11 computer. Can you fix this?

I have used Thunderbird for years with few problems. This evening when I opened it, my inbox was completely empty. I tried all of the suggestions of recovery tools, etc. Nothing worked.I logged in to google and checked my inbox there. Also empty. I recovered most of my emails from the All Mail folder but wonder what caused the problem so I don't see it again.

I changed my yahoo mail account (xxx@yahooo.com) password to counter a threat. How do I change the pw on my Thunderbird account xxx@yahoo.com? I seem to need to provide a pin, but I don't have that.

I created a user profile for IMAP and all was OK....Until I deleted the profile for POP and I lost all e-mail folders that I didn't move to IMAP. My PC is running Linux Mint. How do I get my lost e-mails?

Let me explain there is some one with the following email:

noreply@redcarpetradar.robly.com

Whatever anyone does do NOT click on their links I believe it's a criminal organization trying to get to my account.

I know many of you may not be in my situation but I'm a bit job hungry cause financial hit really hard. I clicked on link without looking and the site pretended I needed to fill a job application out. So I did without looking to see who sent it. Yes, STUPID me.

For some reason I marked as junk and it's not going to where I need to and that is trash and immediately delete it. I try and see if I can setup a rule for that. But wondering if there a extension that might do a better job. I tried to unsubscribe but these guys keep hitting back. That one sign of hackers trying to penetrate.

So now I'm wondering is there anything else I might be over looking. One think I keep thinking about is why NOT put something a tool that will do similar to mxtoolbox. With AI out there it's going to get harder to keep these criminals out of our inboxes.

I appreciate any feedback.
