I have 3 email accounts on Thunderbird: 2 hotmail, one gmail. the Gmail works after the update. the 2 hotmail account do not send emails since the update. I deleted both accounts and put them back in Thunderbird and still do not send email. They download all the emails and folders without a problem.

what should I do to make them work on Thunderbird?

I am using FF on a Windows 11 desktop. When I try to log into familysearch.org using FF, Avast detects that I am being redirected to https://590-buk-726.mktoresp.com. I have used both Avast and FF for years, and this is the first time this has happened. FamilySearch is a very legitimate genealogy site. I contacted Avast and they refreshed FF, and I was able to log in ok, but when I tried it again I got the same warning. I cleared all cookies - same problem. I deleted FF and re-installed - same problem. I am not getting this warning when I use MS Edge. Has anyone seen anything like this? What should I do? Thanks, Mike

In thundertbird 102.11.0 (32-bit). unread messages remain unread aftrer selecting the message. I have to opeen the message in order to mark it read. This is different from what happened beforew. just selceting the message would make it Read. This is slow as I dont always need to open messages In Settings > General, Reading and Display, Automatically mark messages as Read ius checked, and Immediately on Display

Hello,

since Saturday, 9th Sept. 2023, ca. 14:00 GMT my Thunderbirds are producing error messages.

I have added four different outlook.com email-accounts, each with IMAP+TLS+OAuth2 as incoming server and SMTP+STARTTLS+OAuth2 as outgoing server configuration. The error messages are only regarding these outlook.com-accounts. A gmail.com-account with the same settings is not affected.

I encounter constantly popups with the following error messages: - "...user ist authenticated but not connected" - "the server is offline" - something like "authentification error while connecting to server outlook.office365.com"

Also the Page where i should enter the password to create the OAuth-Token keeps opening and closing before it could load completely.

The most astounding thing is, the synchroniziation seems to work nonetheless. It's just the messages that annoy me.

Here is an entry from the Thunderbird error-log: "mailnews.oauth: Error response from the authorization server: invalid_grant; AADSTS50196: The server terminated an operation because it encountered a client request loop. Please contact your app vendor. (...) https://login.microsoftonline.com/error?code=50196"

The problem occured more or less suddenly on 3 different PCs: - Two Windows 10 Pro 22H2 machines with the Thunderbird versions 115.2.0 and 115.2.1 - A Fedora Linux machine where Thunderbird 115.2.0 is installed via Flatpak

What I already tried with no success: - De- and reinstalling Thunderbird with deleting _all_ user Data - Upgrading Thunderbird from 115.2.0 to 115.2.1 - Revoking the access for the Thunderbird-app in the Microsoft.com account OAuth-Settings and granting it again when creating a new token by logging in with Thunderbird

What my inquiry has delivered yet: - Thunderbird seems to have problems to remember the OAuth-Tokens. When I look in the privacy settings at the saved passwords I can see that the passwort seems to change constantly. In contrast, the Google-gmail.com-account keeps the same passwort. - It seems to be especially triggered by closing thunderbird and opening it again shortly afterwards, though it does happen without doing so too. - The error messages pop up and the password-page opens mostly when I click on a folder (presumably because Thunderbird is trying to sync it then)

My accounts seem to be fine. I have no problems accessing them with OAuth2 via K-9 Mail on my Android 13 phone. I can also log in via the Web Interface.

Thank You for your Time!

I have been having this issue for such a long time now but its really getting ridiculous now, I have tried to follow so many guides and re-installs and .XPI installs and nothing is working, I am beyond stumped as to what can be the problem, someone please help me fix this.

In response to Wayne Mery, please find attached a JPG files named "mailscans". This contains your email to me, plus an email from a puzzle supplier demonstrating that the buttons are missing. (for some reason I cannot upload pdf files)

Can I get back to the main layout as it was prior to the Supernova update?

I LIKE the list of correspondents and being able to simply click the dot to mark something as unread etc. etc. etc. Things like this allow me to group and highlight things I need t address.

Truly - the layout in Supernova is terrible and, h0nesty, after many many years as a loooong tie TBird user (like since early-mid 90's) I'm probably going to look around for something else if I'm stuck with this supernova layout.

thanks

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

Yesterday the option to make Firefox my main browser turned on on my Android phone. It won't let me turn it on. I have Google on my phone, but I never updated it, I updated myself yesterday, I can't turn it off. I also have a MI browser that is disabled. When Fitefox is not my main browser, I cannot add web shortcuts to the start screen, and I use it all the time and miss it a lot. What should I do to restore the option to make Firefox my main browser? I used to have Google but now I don't know what's going on? Help me please!!!

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

I have a mail provider that has a funny folder hierarchy like inbox

   trash
   sent
   ...

Basically, all folders are under "inbox".

• • Before version 115.2.3**, smart folders were handling that properly.

Now, when I add that "inbox" in the "inbox" smart folder search, it appears for a few seconds there, then disappears until I actualize" again the inbox smart folder. Sometimes thunderbird crashes/

I use Gmail and TB is continuously downloading over and over.

Why? How do I stop this from making the program unresponsive for 20-30 minutes throughout the day?

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

I am a POP user using Thunderbird Version 115.2.3. I retrieve the mail headers first, then when I click on a message to see the contents of the actual message Thunderbird skips to the next message. The message I had wanted to read now becomes the previous message. I then have to go back and click on the message to see its contents. Please correct.

Hi

I have a setup with my machine where I use different user accounts for different purposes as this helps me manage a large number of different applications and setups. I want to use the same Thunderbird profile for each of these users as I am the same physical person, these are logical users not different people, and therefore the profiles will never be in use simultaneously.

Research on the internet suggests that this can be done by copying the Thunderbird profile to a globally accesible directory and then using the Profile Manager to point profile.ini to the global profile. I have done this but when I try to launch Thunderbird from a different user I get a message box saying 'Thunderbird is already running, but it is not responding. The old Thunderbird process must be closed to open a new window.'. If I click on 'Close Thunderbird' the message reappears. I have confirmed in the Task Manager that the Thunderbird process is not running.

Strangely, if I launch Thunderbird from the command line version of the Profile Manager Thunderbird launches with the correct profile and appears to work fine. A forum post suggested deleting the parent.lock file in the profile and doing this does allow Thunderbird to launch with the correct profile but then I get error messages saying it could not load the message summary as it's too big.

I have looked at this link here but it's not clear what is meant by 'have each user "move it" using the profile manager'. There is no move option in the Profile Manager (as launched from the command line), just Create Profile, Rename Profile (which I've tried as another user with the same problem suggested) and Delete Profile.

Here is my current profile.ini for the users that won't launch Thunderbird.

[Install8216C80C92C4E828] Default=C:\ProgramData\Thunderbird Locked=1

[Profile2] Name=MarkDevelopment IsRelative=0 Path=C:\ProgramData\Thunderbird

[Profile1] Name=default IsRelative=1 Path=Profiles/uzxtlmbg.default Default=1

[Profile0] Name=default-release IsRelative=1 Path=Profiles/hcw0nqcr.default-release

[General] StartWithLastProfile=1 Version=2

Any help would be greatly appreciated.

I am using Thunderbird 115.2.0 (64-bit)

continue in /questions/1424778 in Thunderbird section.

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

After the update I see the three windows, (folders, messages and content) but they are empty. When I select all folders in view I can see my folders, but the messages and content windows remain empty. It does receive messages as I see the number of messages increase. Has the update changed the view settings or is it more serious? I don't dare to change my profile as I have thousands of messages in hunders of folders that I like to keep. I am using windows 10.
