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?

With my previous FF installation, it would remember both the width and the last selection in the sidebar after closing and re-opening FF.

I just formatted and reinstalled windows and now FF simply would not remember the last sidebar condition.

I'm using Windows 10 22H2 and FF 130 64-bit.

I have 4 email account using Thunderbird. These are all domain imap email accounts. They work via the web hosting mail (Yahoo/Turbify). I can access many different ways: Outlook on my iPhone and iPads, Thunderbird on my desktop Mac Pro. There was some sort of tech issue at Turbify where all 4 account are hosted but all email was restored and password were reset.

However, only one account jeff@jeffmunk.com no longer work on Thunderbird, perhaps the most import one. I checked both the imap settings and smtp setting and the authentication and recommended ports and I still can't get that one account to work - but only on Thunderbird. It works retrieving from mail from Yahoo and Outlook, both phone apps or a browser on the desktop. I think I has this issue once before.

This is my original post. No response at all. Disappointing.

Non functioning Export/Import, upload images

At this point, if I could just get an opinion, a direction you might follow, if this was happening to you

It keeps recurring. This time it took 3 weeks from the time that last post. As I said in the past post, the problem is a corrupted 'sessionstore.jsonlz4 file.

My evidence is that when i ran about:support - Troubleshooting, the problem was still happening.

I just mounted a backup profile, created during the last incident. Works fine. I took the sessionstore.jsonlz4 from that backup and replaced the one in the problem profile.

After doing the replacement, the problematic profile symptoms have disappeared. At least for now, that is.

But now, I have to restore the missing portion of the session (tabs/history) created between the last occurrence and now, because of the replacement of the corrupted sessionstore.jsonlz4 with the backup.

Nobody has offered a way to do this that is not a time consuming ordeal.

What would you do?

I'm logged in to Firefox on 3 devices: personal laptop, phone, and computer at work.

I'd like to be able to sign out / log out when I finish work, so nobody can access my data but I don't seem to be able to do that.

In my view it's neither private nor secure. Because I teach, computers in the school are shared by different teachers. When I used Google chrome, I'd log out and nobody would be able to access my data. With Firefox it seems to be different. Why?

I really wanted to switch to Firefox but I don't think it could be an option now. 🥲

Sometime in not more than the last two weeks (maybe just since 9/1/24?) I started seeing this: 1. open new tab, see small FF icon and "New Tab" text. 2. enter URL and press 'Enter', or, click a favorite/hotlink on that page. 3. between that time and the time that the page actually loads, the tab icon changes from FF to the new-twitter "X" icon! 4. the "X icon" remains even after the "New Tab" text changes, and does not change to the icon of the actual web site until after its page has (fully?) loaded. See screen shots. FF version 129.0.2 (64-bit) PS - I do not use Twitter/X. I do not believe that I have ever been there, and certainly not on purpose. I use Duck Duck Go as my search engine I have not done any cache flushing, etc.

Hi,

I have experienced a worrying problem since a few days on Thunderbird client (Windows).

I recently received anonymous emails on my ISP mailbox. The sender has been disguised with display name of some of my recent recipients, but the sender is not visible when I open the message. The mail subject is also taken up from these recent emails. Each of these emails contains one of my personal family photos! These suspicious messages are only visible on Thunderbird 128.2.0esr (64 bits) Windows and not on web mail in a browser nor on the mail client of my smartphone!

Inspection of the message source in Thunderbird does not show the email header... but only the binary code of the image that has been included as an attachment.

It appears these incoming messages were modified locally in Thunderbird because I can see the original and valid emails from the senders in a web browser or from my smartphone. I suspect a malware is corrupting some inbox messages in Thunderbird. Norton did not detect any malware on my PC. Malwarebytes has quarantined a few PUPs/MUPs.

Only one of my mailboxes is affected by this problem. Is there any known vulnerability in Thunderbird similar to this report? How can I block this kind of alteration of incoming mail?

"cannot truely say those downloaded emails are an independent copy because... display whatever is held on server"

Seems to say that TB displays [a message that had been downloaded] not by reading it from folder in computer, instead by reading it from sever. If something different is meant, then please clarify.

I am facing a very strange issue with my website, it is working OK on the Mozilla desktop, and IOS, and does not openly correctly on the Mozilla Android, a lot of users reported this issue to me, which is quite frustrating, can somebody guide me what's wrong here?

Hi, I've started my laptop after 3 days, opened Firefox web browser and all my tabs are closed / lost. If I try History -> "Recently closed windows" is greyed out. How can I recover all my tabs from this computer?

Thank you, Tudor

Hi Team,

Can we get details regarding the latest ESR release (128) installation issue in Windows 2012 R2 server.

We are facing failure issue of ESR 128 x64 in windows 2012 R2 server.

Regards, MM

so I am working through downloading python and chromedriver and dealing with PATH issues re: selenium, pip, etc when I start getting first an email error message:

Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.

I do not have thunderbird open. i confirm in task manager. don't think anything of it. then firefox starts doing the same thing.

at this point, I am already uninstalling the other software above to try a new, clean install and I am required to restart.

after restart, weird stuff. half my desktop icons and explore files are now faded. neither TB or FF will work. I use chrome, see a bunch of the messages on here to first look at uninstalling and reinstall. Do it. Doesn't work. Next step - run down through appdata, roaming, etc to get to the profiles folders and delete the "profile.lock" file

Yes. This works for FF but WTH!!! I open TB and every email is gone. I go thru the process to zip my profile and import. Nope. Doesn't work. So i unzip the file into a thumbdrive and import using eml method.

TB does not keep my original format, duplicates all folders, and anything older than early 2023 is there but there is no longer a subject, sender, etc

I take a break. Today I am back at it. I cannot access new emails at all. I cannot delete the folders so I make a backup folder, uninstall and reinstall TB and the same thing.

How can I reset TB, import the old emails?

What is the importance if anything of profile.lock?

Any thoughts if working through issues on python, etc caused this?

It used to be when I moved from just my laptop to my much larger monitor the layout pane sizes adjusted proportionately. Now for some reason the message pane remains at whatever it was on the last device. Is there a way to change that?
