Hello Team,

Please be aware that we are encountering issues configuring POP for Office 365 using Thunderbird, as it is generating an error stating the username and password are incorrect. Our Multi-factor Authentication (MFA) is enabled, and we are attempting to utilize OAuth2.

Hi,I have 4 email address & my Default Email is ismda3@westvic.com.au(on SMTP) Regardless which email I TRY to REply to.I receive the Samr Message See attachment I am getting very desperate Thanks Darryl

Hi All, I've been running TB on my home desktop since ancient times. Present config has been working for quite a long time. TB manages more mail accounts, of which two connect to my remote server (and two others to gmail and freemail). The day before yesterday evening there was a power blackout while I was using TB. Since then I have the following problem:

1. First mail account says: "Could not connect mail server <remote server>; the connection was refused". Now I cannot even see the sub-folders of this account in TB while the folder files themselves exist. 2. Second mail account (to the same mail server, to another mailbox) works partially, it says after sending an email: "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors."

Connection to mail server is via ssh portforwarding (for TB smtp is localhost:2525, imap is localhost:1143, ssh tunnels work as I can telnet to them and imap/smtp services respond). What is more, from the home desktop my wife (different local desktop user) can normally access her mailbox (different email address on the same mail server) with the same ssh tunnelling method. She was not logged in and was not using TB when the power crashed. After power had come back I ran fsck, filesystem is clean.

So I think that some setting(s) must have gone wrong under my TB profile and it is emphasized more by the fact that in the first case error msg the name of the remote server appears instead of "localhost". Account settings in TB seems to contain the original server settings (e.g. locahost, 2525, normal password, no connection security, etc.)

Only strange thing I could find in Troubleshooting list is that under "Mail and news accounts" it lists account2 (imap) localhost:1143 None Normal password while in the outgoing server column it contains _two_ times the locahost:2525 setting.

In config editor the mail.server.server2.hostname points to the original name of the remote mail server (instead of localhost???).

So what can I do if I wanted to avoid deleting the two mail accounts and re-configure them, especially considering the fact that the mailbox size is about 80 GB.

Any ideas are welcome and appreciated.

Thanks in advance, KEA.

I always had one version of Firefox installed. I regularly update the software via Help >> About Still, after every update, I am getting multiple versions of Firefox listed at [Settings/Installed Apps] and [Control Panel/Uninstall or remove apps] on my Win11 23H2 22631.3593 (screenshot attached).

In order to get rid of outdated items from the list, I need to reinstall Firefox completely, but the same thing is happening with every update of Firefox.

Is there a way to resolve this and why is this happening?

When I download messages, it often says there are say '6 new messages', but only 3 appear on the screen. I'm wondering whether the others are going to Junk, but I am unable to access it. So my question is, how do I access Junk Thanks David White

Windows corrupted my user profile so I lost everything... how do I get my bookmarks from Firefox iOS to my desktop PC?

When I sign into my desktop Firefox it has nothing - I am worried if I sync my iOS firefox it will delete all my bookmarks?

Hi there,

Using the shortcut Ctrl + Cmd + Space is suppose to open the Emoji panel, however it disappear instantly.

I have already heard that this could happen if you download FF in a specific language and then change it to another language (https://bugzilla.mozilla.org/show_bug.cgi?id=1563862). I have deinstalled everything and reinstalled without changing the language, and it still don't work properly.

I'm a swiss french user, so my keyboard is configured for "French - Swiss" and Firefox is in French.

Does some of you still have this issue? Thanks a lot for your help

How do I turn on autofill in firefox 125/126? There are help pages that say go to settings>privacy> and turn autofill on. But there is no autofill mentioned anywhere in that page. The only reference that autofill comes up with when typed in the search bar in settings is in import settings. How is this so difficult to enable, its basic functionality 10 years ago. I've also tried going to extensions.formautofill.supportedCountries and extensions.formautofill.addresses.supportedCountries and adding my country (why this is a thing is bizarre as well).

Hello, I have set up several mail accounts in Thunderbird. Unfortunately, the inbox of one account is not displayed in the Inbox group, the archive of another account is not displayed in the Archive group and the third account has an entry in the Sent group, but it is out of date. Instead, the current one can be found separately in the ‘Folder’ account. How can I fix this in the grouping view?

Firefox just used almost a GB by just opening it! I only typed a Google search, and the next moment my phone tells my I'm out of data!

Note that this is foreground data, not background data. I googled and found answers about media playing in the background, but I haven't watched anything recently, so no streaming link should be active. I installed Ublock origin so I hope that might help.

Attach is my Firefox data usage for the past week of barely using it, except for an occasional Google search.

Good morning, I would like to ask you about differencies (0 messages vs. 4 message) in search in TB vs. Outlook. Please see in attachment. Can you help me with this problem pls? I use IMAP settings in both email clients. BR Tibor

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

I am trying to set up a new account so that I can send email through a mailroute server instead of my provider, comcast. I set up the account without a problem but I get an error when trying to send a message. I was never asked for an SMTP password and none is visible in the Saved Password window.

Hello, I have a very weak internet connection and I've been experimenting with ways to lessen the burden of the slow connection by increasing the time that the cache from websites can stay on my computer (I've already increased browser.cache.disk.capacity and set browser.cache.check_doc_frequency to 2, but the files still end up expiring eventually forcing them to be re-downloaded even though I know these cache files never change).

So far I've had some success with this extension (https://addons.mozilla.org/en-US/firefox/addon/cache-longer/) it definitely works but very inconsistently so I've tried to directly edit the cache files found in Profiles\someprofile.default-release\cache2\entries but every time I edit the max-age on the cache-control line or any other line firefox just erases the cache file completely then re-downloads it.

TL;DR - Is there someway of getting firefox to ignore the cache file expiry dates and cache-control age or at least editing these files to extend their life?

I appreciate any help in this!
