Recently (~January 25, 2023) in Thunderbird (102.7.0) my outlook.com email (SMTP) stopped working with the error message, "Login to server outlook.office365.com with username xxxxxxxxxx failed."

• I see some have suggested changing Authentication method to "OAuth" from "Normal Password" but this has not helped. (Not sure if OAuth is different than OAuth2, but only OAuth2 is an option in Thunderbird)
• I have tried setting the Authentication to OAuth2 in the outlook.com account => account settings => Edit SMTP server
• I have tried setting the Authentication to OAuth2 in the outlook.com account => Server Settings
• In the outlook.com account => Server Settings - Connection security is set to SSL/TLS; Port is 993
• In the outlook.com account => account settings => Edit SMTP server Connection security is set to SSL/TLS; Port is 465

I have searched the "Knowledge Base" to no avail--no solutions, just others with the same problem. Every day a handful of fresh Trouble Reports pop up on my desktop, even though Firefox is not even running (as verified through the Windows Task Manager). It got so bad, I uninstalled/reinstalled and the problem persists. Otherwise, the browser works fine. My expertise lies outside trying to decipher arcane strings of data buried deep in the bowels of my computer, and frankly I should not have to start hiking up a steep learning curve just to get this to stop. I should add, I have been a fiercely loyal Firefox user since its inception.

I'm not super happy about sharing internal data with the rest of the universe, but have done so anyway in hopes we can get the madness to stop!

Current situation: I have 2 monitors. I have the option of auto hide taskbar in desktop mode turned on. On the primary monitor, when I maximise firefox window( not full screen, the button between close and minimise, looking like a square), and hover my cursor towards the bottom, my taskbar doesn't unhide. However when I unminimise( clicking the middle button on the top right again), the taskbar unhides correctly. Also to note, my secondary monitor works completely fine ie, when firefox is maximised I can unhide taskbar on hovering near the bottom.

Thunderbird 102.7.0, 64-bit, Windows 10.

I just fell over this today but it may have been around for a while.

I have lots of email accounts. It was great when TB starting properly supporting a per-account (outbound) SMTP server, however, this seems to have newly broken. I fell over it today, but I don't reboot things for ages so I cannot pinpoint the start.

Here's the issue.

I have accounts on many mail servers, many on the same (mainly att.net, and gmail.com, as it happens).

Each one of them, to send mail, wants me to log in with an individual sending address. Fair enough. This used to work just fine.

However, suddenly, just the att.net addresses are broken. What *seems* to be happening is that the same, single login address is being used for all N accounts. Naturally, this breaks when the login address doesn't match the one on the From: line. So I have to futz around, fiddle around, and so on, and then things work. (I.E. I change the TB settings so that the outbound SMTP auth login matches the From: line, have to re-enter the password, and only then will the message be sent.) So if I have two accounts, x@att.net and y@att.net, only one of them (at a time) "works" with att.net - it's whatever I successfully used last. If I sent mail from x@, this address is being used (and it's in the account settings field. over-riding what was there before), even if I send mail from y@. Or z@. Etc. If I change the SMTP auth address to y@, then that account works perfectly, but x@ doesn't. And so on.

Now the weird part is this: my Gmail addresses still work perfectly. I can send from all of them without changing a thing.

The only thing I can see is that Gmail is set up to use oAuth, and att.net is set up to use 'normal password' (via SSL, so I'm not that bothered about security).

Did I unknowingly manage to break something? Is there a new tweak? Help!

i have windows 11. am on a pc with i-7. my TB version is 102.7.0

i get this error message: jpg could not be opened, because the associated helper application does not exist. Change the association in your preferences. i went to windows default manager, and 'photos' is the default for both jpg and jpeg files.

one TB source recommended going to Tools -> Options -> Attachments / Download Actions -> View and Edit Actions; but my TB doesn't have an 'options' choice under 'tools', and doesn't have an 'attachment' or 'download action' or 'view and edit' choice under any of the headings. my heading choices are 'file', 'edit', view', 'go', 'message', events and tasks', 'tools' and 'help'.

i found a 'config editor' under tools -> account settings -> thunderbird settings (when scroll to the very bottom of the thunderbird settings) -> config editor . there are many many , and i scroll down, but no jpg or jpeg is listed (even when i typed 'jpeg' or 'jpg' in the 'search preference name' box.

what next? please be patient and thorough and walk me through each and every step/click, because i am not very computer savvy.

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

Firefox keeps attempting to access a web site with an unwanted application. The site is mv.outbrain.com and my virus software keeps asking to block the site. The popup is now becoming a nuisance how do I stop it or delete the reference to it

I've used Firefox sporadically for a couple of years. Last week it would not open. I refreshed, then uninstalled and reinstalled and it still won't open. What do I do now?

Ok Guys,

I know you are all very busy, but how long should it take to perfect the "ADD NEW EMAIL ACCOUNT" option in Thunderbird.

I have always had problems (from years ago) adding new Email Accounts, I've learned to manually change the username to reflect, the full email address not just the name, (left of the @ symbol.)

Solution - include the full name ex: "Name@Domain" rather than Name, it would be such a great advancement.

Secondly,

Now on this latest release of Thunderbird (102.7l.00) and a little prior

I have been running into this Strange problem

Every time I add a New Email Account, and click on Done, It spins, and spins, while I wait for TB to add the New Email. and apparently, it never does.

Same problems as before: the Username is incomplete, which is a pain I manually have to configure it and I re submit the Task, and it comes back " Incoming Server Exists Message" Error Message

After maybe 10 years of developing Thunderbird, I cannot understand why this basic of all basic procedure is flawed.

FYI - I have spent the past 1 hour trying to add an email account - and it will not work.

You have any solutions?

Thank you in advance.

I have an email address at an organization that uses Office365. I am able to log in, read and send emails using Outlook either as a standalone app or through a browser. I can also do the same on my desktop with Thunderbird. It's version 102.6.1 (64-bit) running on Windows 10. I must have logged in ages ago and I don't need to do it daily. I use the 2FA mandated by my organization when I log in with Outlook.

Thunderbird is so much better in many ways that I'd like to use it on my laptop as well, but when I try to set it up, it just replies with "Authentication failure while connecting to server outlook.office365.com" even though even the 2FA succeeds. This is a laptop with Windows 10 and TB 102.7.0 (64-bit)

I have checked that (suggestions from other threads): -Cached connections is 1 -IPv6 disabled -Cookies enabled -I cannot set up a app password. I guess not allowed by my organization.

Settings are typical, server outlook.office365.com, 993, SSL/TLS, OAuth2. All that works on TB on the other computer.

Thanks for any suggestions!

We work with Thunderbird on local PC's but for roaming support we have the Thunderbird profiles on a network drive. Lately we noticed that on occasion the network drive is slow or disconnects for a second at which point Thunderbird looses it's lock or the connection to the profile. This results in then giving a popup to reenter the credentials for the mailbox. Is there some setting in Thunderbird where we can tell it to try again for a few times before giving the error?

I found the option 'network.protocol-handler.external.disks' but I cannot find any description on what this setting actually does, is this setting relevant to this issue?

I would appreciate any help you can give us.

When i send an attachment the other party a lot of the time cannot open the file. However in my sent directory the file is always corrupted and shows as 337kb for a 1.5MB attachment and the same for a 6.5 MB attachment. When i send the 6.5MB file to myself in the in box it shows as 331kb. TBird is set as IMAP and the laptop is running Windows 11.

Firefox always uses excessive GPU memory when I watch video and livestream. about:memory shows that the explict GPU memory allocation is only about 200 MB but in the task manager the GPU memory usage is 1GB, and the latter doesn't decrease even if I close the tab. I suspect that this is a memory leak. I searched for Bugzilla and found a similar issue that has been existing for years: https://bugzilla.mozilla.org/show_bug.cgi?id=1386177

I am running win 10 (64) with thunderbird 102.6.1 (64-bit) and in the past 2 days keep getting a pop-up from ieee - I was a member. I contacted ieee and my account was deleted. A full scan using current version avast free did not find anything. I tried logging in and was rejected.

When this pop-up appears, there is an additional listing in task manager under thunderbird.

I find it extremely annoying to keep getting this pop-up.

I am also using comodo firewall.

I am also contacting avast and comcodo.

Any suggestions etc would be appreciated.

Title. Whenever I open Firefox, the window will appear shortly after, but it will take around a minute for websites to load. This applies to both tabs from older sessions and opening new tabs. It doesn't matter whether I've just booted up, or if I've been running for half an hour. I've tried disabling all extensions, but that hasn't fixed anything. I am running Linux Mint 21.1 Cinnamon on my Gaming Laptop. Specs shouldn't be an issue. ANY HELP WOULD BE MUCH APPRECIATED!
