My Thunderbird Version: 115.12.2 (32 Bit)

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide here,

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

And I get to this screen - but my version of the program does not have OAuth2 as an option (see attached image).

Thanks for the help.

Using windows 11 on a desktop PC. Firefox has been my default browser for decades...issues have been very rare. But this is a catastrophic problem. One of those folders contains links to equipment mfrs, the other one has links to dealers and retailers. In the last month TWO folders and all their contents have vanished from my bookmarks sidebar and cannot be found anywhere on my computer. I NEED those folders...Where did they go and how do I recover them ?????

Help to do that will be appreciated!

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

I switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

I am using an older MacBook Pro running Mojave 10.14.6, for which the latest Firefox is 115.12.0ser (64-bit). It has always been working like a champ, but a few weeks ago, individual YouTube video pages look very odd. Usually the related recommended videos are along the right edge in one row, and below the default video window is the title, description, and then the comments.

The problem I have is that these two components became transposed, and if the video is displayed as full screen, the page can be pushed upwards to show the title etc got squashed below the video window, with the recommended videos still in a grid below it. I hope the included pictures are sufficient to illustrate the issue.

Another computer, an iMac running El Capitan 10.11.6, and Firefox 78.15.0ser owned by a family member, does not show this odd phenomenon. I must say I am quite intrigued by this, and would greatly appreciate any help my fellow members can offer.

I'd love to find a solution! Sometimes this happens when opening a link from my email (to a well-known retailer as shown in the images below), and at other times it is in response to a website requesting information as part of a 2-factor ID request or, or even a password change. It has become almost almost debilitating! What setting seems to be wrong here.

I use Webroot SecureAnywhere and the relevant updates are applied automatically.

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

I installed Firefox on a Macbook Pro with Apple Silicon, M3. The installation was from the Firefox site, I downloaded the dmg and then dragged into Applications.

I find that playback of media stutters, and is choppy--not sure of a better way to explain it. E.g., YouTube videos and the Bandcamp player have "stuttered sound". Opening another site in another tab can make this effect worse. Likewise, trying to run Google Meet in a browser window causes basically everything on the computer to become very slow.

This still happens even if I go to "about:profiles" and then "restart with add-ons disabled".

But if I switch to another browser, Safari or Chrome, then I don't have the issue. e.g. I can play YouTube in the background fine even when running some compute intensive task.

I have also tried turning on/off "performance settings" and the "use hardware acceleration" checkbox underneath it -- neither of those seem to have any effect.

Activity Monitor showed that at most Firefox was using ~4 GB of memory of a total 48 GB, and the memory pressure indicator seems to be quite low.

I have run Firefox on other systems (e.g. System76, older Macbook Pro) with multiple windows open each having 20-30 tabs and never had an issue like this.

It really seems like it has something to do with how Firefox is interacting with the M3? Happy to learn I'm wrong. And happy to provide more details about the hardware or my settings if it would help.

I was trying to download ledger live from an official site when I noticed Firefox had twice tried and failed to download an old version of the tor browser I downloaded a long time ago.

A few hours before this happened my pc froze for a minute.

I'm not sure if I have malware on my device or if this is Firefox acting up. My antivirus scan shows nothing.

Greetings,

In Thunderbird 115.12.2 (64-bit) on Linux Debian 12.6, when I examine "Help -> About", cursor movement in the focused information window moves the list of messages displayed underneath in the unfocused messages window. Hopefully the image suggests the issue. Is this an OS problem or something that can be corrected in Thunderbird?

Also, I maintain several accounts, each with several folders. It would be helpful if these all stayed collapsed until selected, with a digit alongside indicating the number of unread messages in each, but recently they each seem to fully expand at inopportune times, making email management rather difficult.

Is this the result of a selectable setting somewhere, please?

When I start a email message search, I am bombarded with bad suggestions for email addresses. These include addresses from everyone I've received email from even though I have deleted these entries in collected email addresses and my personal address book.

The addresses could be from old purchases or ebay responses or anyone I've ever received an email from. I have deleted most of the emails entirely, yet I still get all these bad addresses when I search.

Is there a way to clear the history in search or remove the email addresses where I have deleted the email?

I've attached a Home Depot search as an example.

Since December last about every 30 days or so Outlook locks my account. This only happens when I "hit" send on an outgoing message from Thunderbird. A friend has suggested that Outlook sees my outgoing e-mails as spam and when it reaches a critical number Outlook locks my account. Attached is a screenshot of the error message. Has anyone else run into this problem and, if so, is there a solution? Thanks, Ken.

How do i access Google OneDrive via Firefox so as to delete my sensitive personal info such as financial PDFs and personal pics, which involuntarily got copied to Google OneDrive thru an erroneous mouseClick?

See, when i keyword search online, it states that Google Drive can be accessed via one's browser for purposes of accessing/deleting one's files. (Frankly, i don't even know if OneDrive is GoogleDrive? Is it?

It's upsetting to me that Google has loads of my personal info, because over the years everyone has been saying "Use Gmail", and so i made that my main email due to convenience. But Google now has, for example, some of my personal home photo's and private financial PDFs, all because I absentmindedly clicked my mouse on a risky part of my email attachments, not realizing that would transfer the JPG (or PDF) to Google OneDrive.

I believe this started happening ever since they imposed the New Gmail without giving us a choice. Prior to that, when i used HTMLgmail, i don't recall this happening when i clicked attachments. With Simple HTML, if i clicked an attachment, i saw a photo. It didn't INVOLUNTARILY auto-transfer my pics/pdfs to Google OneDrive, which precisely reminds me of automatic faucets and towel-dispensers and light-shutters in public buildings, all of which are human-unfriendly.

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

Outlook.com and Microsoft inform me that in September 2024, Outlook 2007 will no longer work for email because it does not meet their spiffy new authentication thingy. They want me to quit using Windows 7, but I need it to run legacy productivity software for which there is nothing comparable. So, Windows 7 it is. I do have a dual boot system that includes Windows 10, but I don't want to mess with it for email if possible.

Microsoft suggested that Thunderbird would work, so I downloaded it. That's when everything went sideways. There is no utility to move my existing files and folders intact from Outlook 2007 to Thunderbird. I tried Thunderbird's Import but it refuses to cooperate. So, last chance for Thunderbird is contacting you.

Help me make a clean transition from Outlook 2007 to Thunderbird without losing contacts, folders and files.

Mission Federal Credit Union account page loads but does not allow account info to load. Mission Federal tech say it is a problem with Firefox. Please fix. same problem through two updates of your software.
