Hi. I have used Thunderbird for a long time. I have never had a problem accessing my hotmail account for emails. Overnight Thunderbird now posts error message boxes when trying to login to the hotmail server. It reports incorrect username or password. Neither has been changed by me and comparison with Eset Password Manager shows them to be correct. I can login to Outlook online using the same login credentials an get my emails that way. I have also changed my Outlook hotmail password while logged in in my browser and updated everything on the PC to match of course.

I have massaged the server Settings for hotmail and have had the system working again, for a while. Twice I have reset the settings to a different server and back again and that seems to clear the problem for a while. Then the error messages switch on again consistently. At this moment using "File" -> "Get New Messages For:" -> "Hotmail" works without any problem and the automatic scheduled checking reports "No messages to download" so it appears to be working. But that is after just coming back to my PC to find a string of failed attempts, each with its own error box, which have appeared since I last "fixed" the problem and assumed it was now fine.

My server settings are Type: POP; Name: pop-mail.outlook.com; Port: 995; Username: same as for browser access (which works); Password: As in Thunderbird's stored passwords matching Password Manager and working browser access.

In my paranoia I have even wondered if I am being locked out by Microsoft somehow. Can anyone suggest what is going on here?

I have used Thunderbird for many years without a issue. But as of a couple days ago I have been getting errors when I open Thunderbird. 1) It always ask me to login even after I save the password to always login. 2) I get this message: "Login to server imap.comcast.net with username caulkerguy@comcast.net failed." 3) Then I get this error message "Alert from account caulkerguy@comcast.net 1014." I have checked all my Server settings and all are correct as per your online settings. I have searched the web and have not found any fixes. Are there any fixes or work arounds? I would hate to stop using Thunderbird as I really like it! I have included 2 screenshots.Thanks for any and all help! Mike: caulkerguy@comcast.net or caulkerguy@gmail.com

I like to split windows so I can have running YouTube videos on the left half of the screen and browsing the web on the right. If I open another site on the right side of the screen that has multimedia (ESPN, CNN, IMDB), the video freezes on the YouTube window but audio continues to play without issue.

I have done the following troubleshooting steps:

• Hardware acceleration turned off/on
• cleared cookies/cache
• A few About:config fixes

Videos don't have a problem running if I open YouTube with Chrome and continue to use Firefox for surfing.

Here in Jan 2024 suddenly TB will no longer connect to any hotmail or outlook..it says I have to enter a new password but I have not changed my password and can get onto them if I go directly to that site. Any suggestions?

"Enter Password" box no longer comes up when I start up Thunderbird. One account has password saved but the other doesn't so I cannot access emails on this account now as they won't download without either a saved password or (as I usually do) entering a password. This affects my husband also so not just something on my account. This happened around the 20th December. I've searched through Thunderbird settings but I can't find any way of adding a password directly into Password Manager - only edit or delete. So I can't fix the problem we now both have with accessing new emails. So - any suggestions please or is there a fix coming?, kind regards

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Hello, today firefox has been appearing as a blank icon on my taskbar. I have tried solutions suggested in older posts but it did not help unfortunately. if i try to

1- right click unpin from taskbar the icon shows once more. 2- right click, the icon disappears/becomes blank. 3- click pin to taskbar, the icon remains blank.

attached is the image showing the steps i described above

On November 22nd, 2023, when the application got its last update, everytime I open a new tab it stops loading the website half-way. And it blocks every other tab I have saved for later from loading again. It works after I erase cache 5 or 6 times. I had no problems like this one in the past.

Since a couple days ago I cannot Copy anything in Firefox. Be it with CTRL+C or RightClick>copy. I can paste juste fine, and it works on any other app and browser I own. I tried to restart in safe mode (no add-on) but the issue persists. I ended up resetting firefox and it solved the issue... For a couple hours.. then it came back and I can't copy anymore. I did check that I was using the latest version of Firefox windows. I only have two add-ons, but since in safe mode it still doesn't work I'm not sure it's related to that. I also checked that Firefox was allowed in the firewall (I don't know why that would help but a forum said to check that).

Thank you for your assistance:)

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

https://www.cibc.com/en/journeys/new-to-canada.html

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

I use dark mode (Windows 10 Pro, Thunderbird 115.4.2 (64-bit)). Fresh installation, fresh profile. When I reply to some emails, the reply text is not visible. The examples I saw were with a light (white?) background, but I'm not sure if it also happens with other backgrounds. But it's not all white backgrounds either, some emails with a light background I can reply to just fine.

The reply area can be dark with a dark grey font (slightly different color), or it can be white with a white font. In both cases, obviously the text I type is not readable.

Any idea how to fix this?

Hi All, Greetings!!! For the past two days, I have got the error like "Sending of the message failed. The message could not not be sent because the connection to Outgoing Server (SMTP) timed out". So I have restared our router (Broadband Modem), and then tried to send the mail, but the result is same. Then I have tried using my mobile network (using hotspot method), this time mail was sent sucessfully. Please help me to solve the issues...

Thanks Karthik

Upon initial setup, Thunderbird says the ISP is recognized and auto-populates all the settings. Well of course these settings don't work and I'm unable to log in and receive some sort of message saying it didn't work. If I login using a browser via cellphone, I'm provided with the list of settings to use with email clients which is as follows:

Domain: @hot.rr.com SSL: On for SMTP and IMAP Protocol: IMAP Incoming Server: mail.twc.com Incoming Server Port: 993 Outgoing Server: mail.twc.com Outgoing Server Port: 587 Requires Authentication: Yes, or checked

Using these settings in manual configuration results in receiving the "Thunderbird Failed To Find the Settings For Your Email Account" message. The only difference between the settings that were auto-populated and the settings provided by logging in via web browser on a cellphone are the incoming/outgoing servers. Auto-population had them as mobile.charter.net, and they're listed as mail.twc.com by the email provider to use with email clients.

I'm trying to solve this problem for someone else and they happen to have the same email domain as me so I can fiddle with it without having to be at their computer with their passwords, etc. Presumably if I'm able to find the solution it will work for both of us. I don't normally use Thunderbird or any other email client, I just use web based email but they prefer to use a client. However, I'm doubtful that it will work considering the fact that settings provided by the email provider don't work.

Any input is appreciated.

Hello, I am running Ubuntu 22.04 (Firefox v 121.0) on a custom PC. Ryzen 5700G, 32GB Ram, 2TB Storage, and a Radeon RX 580 (just to give some insight into the system in case it is useful). I use multiple mozilla services and haven't had many issues up until now. Everytime I open Firefox it immediately it fires right up, the moment I try to open a tab, search, etc.. it begins to lag. It will then freeze the browser and my entire PC soon follows suit. I have had to hard reset the PC about 3 times now. I originally had the snap version installed and thought that installing the deb package would fix the issue. I completely uninstalled the snap version and turned off unattended installations in case the system tried to reinstall the snap. I then installed the deb package and fired it up again, only to have the same issue. I have ruled out a couple of things on my end. I entered Firefox Safe Mode and unchecked all of my extensions (the only ones I run are Ublock, Bitwarden, and Relay). I ran a mem test and have been monitoring Psensor to ensure the CPU wasn't overheating (both of these tests were fine). I also scanned my entire PC to ensure I did not have any viruses (clamscan reported no viruses). I have been running my PC for about an hour now without starting Firefox and using Chrome, and I have had no issues with freezing or anything similar to what happened with Firefox. Not sure where to go from here. I love using Firefox and would love to get back to surfing as soon as possible! Any tips/help would be greatly appreciated! PS I could not find any logs about the session. I looked in ~/.mozilla/firefox/Crash Reports/events and couldn't find anything. If there is another place they are stored let me know and I would be happy to send them. I just don't want to open Firefox until I feel it is safe for my PC.

I forgot to add: I disabled hardware acceleration as well, did not fix the issue.

This is probably a mess of my own making, having been lazy about back ups. My laptop threw a critical error at me just before Christmas and I could only fix it by doing a reset and reload of Windows 10. (I think it may have been a partial HDD corruption) I selected the option to retain personal data files etc, but the reload wiped almost all my installed programs, including Thunderbird. Documents, etc folders have all survived. I re-installed the latest Thunderbird and it is working fine. However, I appear to have lost my Local Folders (as well as my address book) Not a life-or-death matter, but I would prefer to recover them, if possible. I have an "..@tiscali.co.uk" (TalkTalk) email account, with IMAP settings on the incoming mail and SMTPS on "sent" items. I can see all incoming emails that are still on the server, but the "sent" items folder is empty. All local folders and contents are gone. I have read up on the Thunderbird Profile and understand that it is separate from the program folder. I have used the "Help>Troubleshooting>..." feature to find that my current profile is "zqx......default-release". Using file search, it also indicates that there is another profile file, "k32....j5.default", in the same area. Both have creation dates corresponding to the reload time. I cannot find anything similar in the "Windows.old" folder that was created at the time of the reload. Is it possible that the folder contents are still in the HDD and it is just the file address that is lost? Thanks. Neil
