I am getting the following error message: Platform version 131.0.1 not compatible with miniversion. Please see the screenshot attached for further details. I cannot open firefox due to this error message and I receive this error message every time I try to open the Firefox.

I have Thunderbird 102.15.1. I can receive emails from my Hotmail account (set up as POP3), and up until 22/09/2024 I could also send emails through Hotmail.

At some point after 22/09/2024 I am no longer able to send emails through Hotmail.

I have the following setting for the outgoing server (SMTP) (which worked fine until 22/09/2024):

Description: hotmail server name: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: Normal password

When I try to send an email I get the following message:

 "Enter your password for adriharp@hotmail.com on smtp.office365.com:"

with the password dialog box underneath.

If I change the authentication method to OAUTH2 for the outgoing SMTP server, I very briefly see the "enter credentials" screen flash up, then the Sending message box appears and Thunderbird hangs until I hit the Cancel button. If I leave it to run, I get this message:

 "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again."

If I try to generate a new app password in my Microsoft account and enter this with the outgoing SMTP server authentication set to Normal Password, I get this message:

 "Login to server smtp.office365.com with username adriharp@hotmail.com failed."

I use OAUTH2 authentication for the incoming Hotmail server (SSL/TLS on outlook.office365.com). This works fine.

My questions are: - does anyone know why this change happened in the last few weeks ? - how can I change my settings in Thunderbird (and/or Microsoft Hotmail a/c) to send emails via my Hotmail account ? - do I need to upgrade Thunderbird to send emails via my Hotmail account ?

I am running Windows 7 on this laptop so I think my options to upgrade are limited to 115.10.01.

Thanks for your help.

For the last week every time i open firefox developer edition or a new instance of it the plus button for creating a new tab is moved to the far left of the tabs bar when it normally should be to the right of the latest tab, in the customize menu when i move it it gets moved to the right of the list tabs button when normally it should be to the left of the list tabs button, the plus still appears next to the right of the farthest tab when out of customize mode but when i open a new instance of firefox developer edition it does that again.

I had a firefox account on my pc then i changed the windows version when i downloaded firefox on the new windows and logged in (i forgot the password so i had to reset) i cant find my old data i tried syncing note that i have changed windows alot and never faced this issue

Hey there! System: Windows 10 x64, Firefox Nightly.

Problem: Out of the blue, when I start Firefox Nightly (I think 2-3 days ago), it just crashed with no extra info. I see the "window of the update process", it goes to the middle or to the end, immediately closes and doesn't bring up the Crash reporter. However! When I tried to run a Nightly Installer that I downloaded through Chrome, it quietly runs and then just opens up my browser no problem, profile and all. I checked and it seems to be the exact same .exe file (according to the Task Manager).

So in short: it breaks if I run it straight from my usual shortcut, or with .exe. But if I run the installer myself, the browser opens up fine.

However, the installer didn't bring any new updates that would fix the problem, I have this for 2-3 days now, I don't remember. I start working, I see I didn't fix it and run the installer again.

Any ideas on the fix? I would love to not lose my profile, settings and, if possible, tabs. I'll try disabling all the extensions after I post this, I don't think they contribute, though (seeing how the external Firefox Nightly Installer opens up my browser just fine).

Thanks in advance!

My name is Raymond Timber, and I’m a DoD Contractor with DISA J6 in Hampton Roads. Could you please provide me with the latest copy of the TAA Compliance document? I need it to request an updated version of Mozilla Thunderbird 128.x ESR. My contact info is Raymond.timber.ctr@mail.mil

I am using Firefox 130.0, 64 bit, with Duckduckgo search engine and TB 128.0.3. I have six email accounts with my Internet provider CTI. I use the same password to log into CTI. I select: "Enter your password for (account name) on mail.pa.net." I select: "Use Password Manager to remember this password." That one login activated all six of my accounts. Using earlier versions (V28) of TB, I logged into only one account on CTI and all six accounts activated and remained active until I logged out at the end of any session with CTI. Now the passwords must be entered individually for all six accounts and each account times out after a few minutes of inactivity, then I have to relogin for each account. What happened between V28 and V 130 to change that procedure and can I fix it? CTI explains they did not change anything on their end. Thank you, D. Gordon

I have installed T'bird in a new replacement pc and also added my two accounts. However, I now need to include my many Local Folders using Profile Folder information from the old pc.

Should I delete all the account information I have installed in my new pc T'bird prior to installing the Profile Folder copy? Thanks Ron

bold text Previously I put the mouse on bottom of very long list and pushed them up until I had a workable IN BOX list. They were not lost they kept the displayed list the same as I deleted emails after reading.

One of my inbox and sent folders (for one particular email address) lost most of its contents. I was able to recover the contents of the inbox folder by using "repair" under "properties" of the folder, but it didn't work for the sent folder. I've tried importing and restoring backups to no avail. I noticed a big change in the size of the folder in a series of Acronis backup files, but can't seem to bring the contents of that backup into Thunderbird. I've tried creating zip files and importing, but nothing works.

When I open Thunderbird (Mozilla), my files are not current. In other words, the most recent emails, probably since the last time I used Thunderbird, in my file folders are missing. I have tried changing the server settings but I think they are correct. Please be patient with me, I am unfamiliar with all the terminology, etc. Also, when I first enter Thunderbird, it does not recognize my password. A window opens with the message "Login to server imap.postoffice.net with username john.fn@usa.net failed." That message also appears when I click on Get Messages. Thanks for any help.

I am confused by Local Folders and have never deliberately used them.

Due to a problem with sending outlook emails I have removed all the accounts and reinstalled Thunderbird but first in the list is Local Folders - which maybe preventing me seeing all in boxes unified - so how do I get rid of the Local Folders accounts or atleast make it the last in my long list of email accounts?

Some help regarding sending from Outlook.com accounts willl also be welcome - but I seem to have a Microsoft problem as Hotmail emails are being sent without problems.

I am not IT competent.
