One of my local folders of email disappeared: it is no longer displayed under Local Folders. A few days ago while using my mouse to move a message into one of the local folders, something happened, a peculiar message briefly displayed. At the time I did <Ctrl>-Z to undo whatever happened, but I didn't see any changes. That must be when the folder disappeared, but I'm not sure.

My other folders are still in place. I can't find the missing folder inside any of the other folders (junk, deleted, archive, etc.). Yet when I search for email in one of the missing folders, the messages are found. When I go into Troubleshooting Information, there is no Profile Directory listed, and when I click on the Open Directory button, nothing happens. (I've gone through the process of transferring Thunderbird accounts to new computers in the past.) I'm using Pop!_OS 22.04 Linux and Thunderbird 140.10.0esr. I backup my laptop using Back In Time. Any idea how can I fix this?

Hi.

I am running Firefox 149.0.2 on Arch Linux (Linux 6.19.12-arch1-1 (x86_64)). I have configured Firefox to use the "~/downloads" folder for downloads instead of the default "~/Downloads". I have also checked the "Clear cookies and site data every time you close Firefox" box in the "Privacy & Security" tab of the settings page, and configured the History settings to "Never remember history".

The Downloads folder I have set is indeed respected by Firefox: all files I download are saved to "~/downloads". However, every time I close Firefox it creates a folder entitled "Downloads" (with a capital "D") on my home folder. I do not want this folder to be created.

This really looks like a bug from my perspective, but is there some way yo fix this via the "about:config" tab? Thanks for the attention.

Hello!

I have installed Thunderbird 150.0 on an Ubuntu 24.04 desktop using a downloaded TAR installation method. I have done this, as I use OWL for Microsoft Exchange accounts. OWL works better with the current version of Thunderbird.

I have created a desktop launcher (thunderbird-150.desktop), which works fine, except that the software icon is the generic Gnome gear. I have read that specifying the WMClass correctly in the launcher file (in /usr/share/applications) is the solution, but this does not seem to work. It is current set as WMClass=thunderbird. I have also noticed that the /opt/thunderbird/icons folder does not contain the Thunderbird icon.

Can anyone help me to fix this annoying issue?

Many thanks!

Hello!

I am using Thunderbird 140.9.1esr (64-bit) on a Ubuntu 24.04 system. Every time I restart Thunderbird, it reverts to a little used Gmail account as the default account. I have several accounts, but my main email account is a MS365 account. I reset the setting, but every time it is restarted, the default goes back to Gmail. I have tried everything that I've found online, but cannot correct this behaviour.

Do you have any suggestions or assistance?

Many thanks!

There must be a way to turn off this popup off. This is REALLY annoying when it covers a password box and to remove it i must click outside it and I lose focus on the password box. If you must put he box there then at least leave the first part of the password box clear so I cab click on it and not have to click again to get the focus back.

Please forgive me if this question was already answered and that I might have accidentally overlooked that answer.

I'm running Firefox 144.0 (64-bit) under Debian 13 (linux).

I want to configure Firefox to never restore any previous session when it starts up, irrespective of how Firefox was last exited.

Even if a running Firefox session was externally killed via some sort of system command or because of a reboot, I never, never, never, never, never, never, never, NEVER (!!!) want it to restart in any previous session.

I ALWAYS (!!!) want Firefox to launch with its default start page, no matter what.

I tried all of the suggestions that I have found on line about how this might be accomplished, but with each one of them, there are cases where the previous session was restored.

I repeat, I do NOT (!!!) EVER (!!!) want the previous session to be restored, under any circumstances.

Is there a way to accomplish this?

Thank you in advance for any suggestions, and again, please accept my apology if this has been answered and I overlooked that answer.

bold texti have a thunderbird profile on exterior drive I have installed linux mint on my PC but cannot locate the profile to use my old TB profile -either by replacing it or renaming the old profile for the linux one

When I try to save a file, if the target exists, Firefox defaults to overwriting. I'd rather it default to cancel. At least it works this way in Linux. It defaults to cancelling in Windoze.

I thanks you for giving me the ability to use use firefox wihtout AI (by turning it off in the setting, you did it, love you, love you, love you), so really I can't use AI, I don't use regular trnslation that AI enable like google traduction, and chatgpt etc.., I see from my use of them start, the soft skills go very below, they really kill my soft skills I am trying to avoid them as much as possible, and thank you for giving me a choise,

I have my personal account with my personal email setup in both my home PC and laptop. I want to setup a new user profile linked to a work email to hold those passwords and bookmarks separately, and be able to sync it when using my laptop as well. I would also like to be able to have both accounts open at the same time in different windows (i.e. a "work window" with the work account, and a "personal window" with my personal account)

Is this possible? How would I go about it? I looked around the about:profiles tab, but that seems to only configure profiles for my already logged in account (the personal one). I think that what I should do is create a new firefox account with my work email and give that account a profile, but I don't know if I can be logged in to 2 accounts at the same time, and I'm not sure Firefox will show me both profiles at startup, or only the ones linked to the currently logged in account. I haven't tried this because I'm unsure if I could lose my currently open tabs.

I'm a bit lost with the instructions http://mzl.la/1BsOG2o My thunderbird looks different I don't see a "Trust junk mail headers set by" option. What would be the proper way?

I deleted an old email address for a friend, but every time I email her, the auto-complete feature includes both the current email address and the one for her old job. I've deleted that one, and it doesn't seem to show up in the Address Book anywhere, so why does it keep coming up in the auto-complete?

It's annoying to me and to the place of employment to have the emails go to the wrong address when I'm not watching very carefully.

How can I make sure this doesn't happen again?

" attach the signature from a file instead "

I put the URL in there and it does not retain it and use it as signature image. It is a jpg. It browses in a URL on my browser and loads fine but T/B refuses to allow it.

Suggestions ?

An Add-on (a theme) I've been using, Graphite Grace by compilan, has been removed with the following message:

"This add-on is blocked for violating Mozzila's policies and has been disabled".

As a user, I feel I have the right to know what policies were violated, and whether the add-on was indeed malicious as well as what data may have been compromised. Where can I get that information?

I am the developer of FastF1, an open source Python package for downloading and analyzing Formula 1 race results, timing data and telemetry. The package is widely used in the fan community for independent analysis of results. For some advanced features, the addon requires users to authenticate with their Formula1/F1TV account. Since their services don't have an open login API, a companion addon is required to allow users to sign in using their browser and the official website.

I have just noticed that my developer account has been banned and the addon was blocked in Firefox. I have not received any email about this and don't know why exactly this decision was made. I'd like appeal this and reinstate my account and the addon, but I don't know how to proceed from here.

FastF1 and the companion addon are fully open source and intend no harm to users. https://github.com/theOehrly/Fast-F1 https://github.com/theOehrly/fastf1-companion

I hope this problem can be resolved.

Upgraded from `102.15.1` (deb) to `140.9.1esr` (flatpak).

Now for all my Imap folders the default action (double-click) is `Edit Draft` instead of `Open`. This is confirmed by right-clicking and having `Edit Draft Message` in bold at the top of the list.

How can I fix it?

- imported old profile with `⁝` -> `Tools` -> `Import`

- found https://support.mozilla.org/gl/questions/1364428 and tried the addon it recommended but none of the imap folders were flagged as draft.
