Hiya,

I just started setting up Thunderbird and I have come across a bug. At least, I think it's a bug.

The situation: I'm viewing favorite folders and unified folders. What I want, is to show some unified folders in my favorite folders. That is, my unified inbox, drafts, and sents. So, I right click on them, I select "✅ Favorite folder" and they appear among my favorite folders. All good, right? However... When I restart Thunderbird, the unified inboxes have disappeared from my favorite folders. And when I right click them, it still says they are marked as "✅ Favorite folder" And the way to make them reappear is by deselecting and reselecting them as favorite folders. See the picture.

So, what is happening? Is this a bug? My guess is that it is. Could anyone help me to circumvent this?

Hello,

Is there someone who cam help me fix a 'constant mail delivery failure' issue ?

I've been experiencing for a while now that some emails I'm sending get returned with the 'mail delivery failure' notification.

Recently though I added a new email address to the Thunderbird dashboard, and when I am sending an email from this account I now get a 'mail delivery failure' notification with every email I sent.

I used to shut down my laptop, and restart it again, and usually that enables the email I've tried to send go through.

At this point, with that new email address, this trick doesn't even help anymore.

If there is someone knowledgeable about this topic, and willing to help me out, please do.

Kind regards,

Christiaano

In recent weeks when I open my Macbook and go to https://meet.google.com, the page that loads says "404. That’s an error. The requested URL was not found on this server. That’s all we know." The issue is only on Firefox and not Chrome or Safari. When I see the error page, I look at the URL and it has the word "unsupported": https://meet.google.com/unsupported?meetingCode=landing&ref=https://meet.google.com/landing

So I dragged firefox to the trash, reinstalled and the issue persisted. I do not have a VPN. I'm using my own Wifi at home. If I switch to my desktop computer (m2 mac ultra) and go to the same Google Meet URL, I don't get a 404 error on firefox, however no one can hear my microphone any more as of 1 month ago, when I didn't have this issue in the past and I've done everything that everyone has told me to (in order to fix it) and nothing has worked.

Laptop: MacBook Pro 2021, MacOS Sequoia 15.0 Firefox: 13.0.1 (64 bit)

I have Firefox's New Tab set as my home page, since I'm choosing to divorce myself from political doomscrolling for the next four years. The New Tab page is perfect for having frequently visited sites at the top, Pocket stories I can curate in the middle, and what used to be a history of articles and sites I've read most recently in "Recent Activity" along the bottom. Within the last few days, "Recent Activity" has been blank, and will no longer keep track of articles I've recently read. I've tried clearing the browser history and cookies, and it came back for a moment, but quickly went back to being blank. And the major downside to clearing the browser is that my four rows of most frequently visited sites gets wiped clean also, and I have to spend time getting them back on the list. I do not have Firefox set to automatically clear history upon closing it. I've tried turning "Recent Activity" off and on with the page's Settings (cog in the bottom right corner). I'd really like to have this back, as it can help me find recently read content (especially Pocket content) easier than wading through the History log. Any help would be appreciated.

I am trying to manage Firefox for company devices via Intune and would like to know if there is a way to uninstall all extensions/add-ons besides one or two approved ones.

I have been able to import the Firefox AMDX into Intune and have made a policy to install uBlock (which works without issue) and I can uninstall specific extensions/add-ins via their Extension ID (also without issue), however I can't see a way to uninstall all extensions. If I try and put a wildcard in the Extension ID field, nothing is affected.

We have a large number of devices with their own user-installed extensions so auditing this and then updating a policy manually with specific extension IDs may be quite painful.

Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!

I have just got a new laptop and installed everything in relation to Firefox onto it. I have used the Nordpass extension for a couple of years and on the old laptop this is version 5.23.13 updated 16/10/24. On visiting the add-on and extension site today there is only a legacy version 4.33 updated 2y ago which clearly no longer works. Where has it gone. Clearly I am going to ask the same question of Nord, but I hope you can help.

I tried the help article, but it seems to be out of date and doesn't match what I see.

I have an Inbox with 4 emails.

Then I have another email that has an inbox beneath. I'd like to add this fifth inbox to the global inbox.

I am not getting my email on Thunderbird. I am getting this message: "Could not connect to server pop3.optusnet.com.au; the connection was refused" Could you please help with this? Kind regards, Luke

As of yesterday afternoon 1/8/2025 Thunderbird crashes every time it opens. I tried troubleshooting mode, but it still crashes.

These are the last five crash reports I submitted:

bp-b06aee68-741d-4f5a-8bc4-c15230250109 bp-82e871d5-0479-422f-9ee1-c0d3c0250109 bp-de082294-4c7b-48e4-a20e-db4730250109 bp-993f1d6a-4671-47bf-9d9a-5da6a0250109 bp-6b4de7fd-a602-4632-ae48-961690250109

Please contact me at my alternate email account: tvcrider@gmail.com I suspect that I will not received notices when someone answers this thread. I pretty sure my account is tied to my Thundebird email. Thank you, Joe G

Hello, I recently switched from Chrome to Firefox because of privacy concerns. I exported all my saved passwords from Chrome and now I want to import them into Firefox in one click. However, I couldn't find the "Import Passwords" button or interface in Firefox.

Could you please guide me on how to import my passwords? Is there an option available, or do I need to enable a setting?

Thank you for your help!

Running Firefox 133.0.3 on Windows 10 22H2

The last week or so, when I try to download my photos from iCloud, Firefox blocks the download, saying it contains a virus or malware. Of course it does not - it's a zip file of screenshots! Running a scan on the folder once unzipped confirms there is nothing malicious in it. Can you fix that please?

I’m using Thunderbird on a MacBook Air M1 2020 with 103 GB of free disk space and 8 GB memory. I’m using it primarily as a calendar and task management system because I like the reminder options in Thunderbird. I use local calendars. Thunderbird auto-updated to V 128.5.2 from V115.18.0 on 12/17/24 (I didn’t realize auto-update was set) and since then gets hung every time a reminder comes up and I either dismiss it or snooze it. I have to Force Quit Thunderbird to get the spinning beach ball to go away. I backup my computer weekly using Time Machine and tried restoring to 115.8.0, but was unable to restore my profile with my current calendar items on it. I got an error message saying that the new version of my profile (with my local calendars) is incompatible with Thunderbird V 115.8.0. Is there any way to get my current calendar info into an older version of Thunderbird, or better yet, create a fix so that it doesn’t get hung? If it's time for me to move to a different application for this use, just be honest. Thanks in advance for your advice and expertise!

Hello,

I have problems with instalation of True Key on Firefox?

I can't install the True Key add-on by McAfee!

After downloading it, I can't run it as recommended.

Can anyone help me to make it to work correctly?

Thanks in advance.

When I attempt to add a Gmail account, I get this error - "Unable to login at server. Probably wrong configuration, username, or password"

Below are the steps with screenshots: - checked for no cookies to prevent Google from asking for an actual login - no stored google passwords - didn't put in my password on setup - TB finds the available configuration - prompted to login at google - add google password - allow access - error message

I have restarted Thunderbird. I have checked for updates (even though I have it on auto-update).

Are there settings on my Google or Gmail account that could prevent this from working?
