I've been unable to use TB since July/August 2025. I don't have detailed documentation of the details, but my recollection is that an error was occurring whenever I would try to send an email. My troubleshooting led to the possibility that the problem was with the SMTP protocol.

  Please let me know whether anything more was contributed here in this forum. Meanwhile I will install TB again and try to re-created the problem.

Thanks for your help, SweetTasha

I just updated my browser less than a week ago. Today I got another notification for yet another update. This logs me out of everything.

WHY so many and so frequent are firefox browser updates. I am about to stop using this brower if it continues. It's very disruptive!

Thank you for your attention to this.

Hi,

I am trying to remove a large number of e-mails from my Inbox. The standard advice says to hold down Ctrl or Shift and select e-mails, then right click, and choose rubbish bin symbol to delete. The advice says you will get a confirmation message, but that doesn't happen. Only the e-mail right clicked on actually deletes; all the rest stay put.

I have tried deleting the trash file to force it to recreate. I have tried updating Thunderbird, but I'm already on version 145.0. I use gmail.

Does anyone know of a working method for doing multiple deletions?

I was trying to change the time emails are kept on the server so I went into "Account Settings" and now Thunderbird is locked onto this page. I get a "Mozilla Thunderbird not responding" message when I try and click on anything and I can't get out of this page nor access my Inbox. I've tried starting Thunderbird in Safe Mode which didn't work. I then uninstalled and reinstalled the latest version of Thunderbird but when it starts it goes straight back to the frozen "Account Settings" page. I've checked my profile and there is a new profile that was created with today's date. There is also a profile from June 2025. If the old profile contains all my emails and folders up to yesterday, that would be OK.

I've been wanting to access Thunderbird's encryption ability on both my laptop and desktop. However, in setting up Tbird on my laptop I notice the user Profile should stay on one computer. Can I use the same Profile on more than one computer using the same source and password? Can I open a new profile on a second computer, even though I would have to use the same email source, a local provider? If not, is there an online source of email data I can use on Tbird on my laptop. Thanks much, Bruce Bartrug

I use a Mac running macOS Sequoia 15.7.2. Each time I attempt to login to https://music.amazon.com, Firefox freezes which then requires me to quit Firefox and restart. Therefore, I need to use another browser to access the site. What is the solution to this issue?

I've been using Firefox on Mac and PC for many years, and been on Twitter/X for 12 years. Never had a problem before this.

X is now requiring users to enter and verify a 4-digit passcode to be able to use the DM feature. Firefox on Mac won't let me do this. Every time it produces an error message:

"Unable to load encryption module. Please refresh the page and try again."

But when I do it in Safari, or Explorer, or Chrome, it lets me do so.

The problem is, most of my data and resources are on my Macbook, and I have not been able to find a workaround. I've cleared my cache, made sure I'm on the latest version of Firefox, restarted it several times - same thing.

I need to get this fixed. Please help.

I have a rather strange problem and I'm not sure this is the right topic. I generally use my computer on and off all day and I never lock it until the evening when I turn it off. I went out for several hours today and when I came back there was a new version of Firefox installed. When I opened Firefox I realized it was a new version because it would not let me logon until I had completed a profile. My old version never did this. In addition all of my saved passwords had disappeared as well as my bookmarks. I'm using a Dell laptop running Win 11, about 2 years old. I don't understand how this could happen. There was no one here while I was out. I looked to see if there was a saved profile but only the one in use showed up. The current version appears to be 145.0.1. One thing that might have something to do with it. I might have been asked yesterday if I wanted to synch firefox on my computers but I'm not sure how I answered this (I'm almost 90 and my memory is a bit imperfect).

I do have Firefox on a second desktop which is running Win 10. Is it possible to use that profile. That computer has not been turned on since this happebd and is currently asleep. Any help or suggestions will really be appreciated!

I'm just getting set up with Thunderbird. I used to use Postbox, and imported my Postbox profile into Thunderbird, which overall worked great – it got all my local email folders, and brought in my Apple email account, and so forth. The only wrinkle I've noticed so far is that it also created an account named "server7.invalid" that I can't delete. If I go to Account Settings, for "server7.invalid" it states "The following is a special account. There are no identities associated with it." The only items underneath it are "Spam Settings" and "Disk Space". There is no red Delete button for it, the way there is for my two real (IMAP) email accounts. Viewed on the Mail tab, it appears to contain only "Trash" and "Outbox", and both of those are empty. This weird invalid account doesn't seem to be doing any harm, but of course it is ugly and I just want it to go away. Help?

Yesterday, I thought I had my original problem with TB fixed by installing v140.5.0. Well, things just got worse.

While trouble shooting it today, it AUTO UPGRADED to v144.0.1.

When I set an event or a task to go off on a certain date and time, nothing happens when the set time is reached. I used to get a pop up showing the event or task on my previous pc with Windows 10. This new pc is Windows 11

Lately , when accessing some sites , I have been getting a blank screen with a video ad for Pandora Jewelry in the upper left corner. It takes over the tab a few seconds after opening the site. Does not seem to affect most sites (yet). Did a virus scan and a Malwarebytes scan. Both came up clean. Cookies and cache were deleted and the system rebooted. No luck. Tried restarting FF without extensions with the same results. The screen does not allow a screen shot.

Anyone else seeing this? Any clues? I am using Windows 11 Pro.

Unfortunately the latest release has broken the ability to support the NordPass extension. I also have WaterFox as a backup based on historical usage challenges, and sure enough it supports NordPass with no issues.

The issue is when a user completes the Account login to Nord itself, then enters their master password for NordPass via the browser. It then gets lost, presenting the animated circle as if it is attempting to process the next step, and it fails to exit that state.

Been using thunderbird for years, stopped getting new messages. Removed/deleted the accounts and tried to setup again and get error unable to login at server, probably wrong configuration, username or password. username and password are entered correctly, changed them just to verify, using default settings and appear to match what their supposed to be as documented. Gmail accounts... Any help appreciated...

I only get that damn "JSON, Raw Headers, Data" screen when I try to go to gamestop's website. HOW do I fix this? This is only the latest in a long string of stuff your browser does badly, and if not for the fact you are the only browser Youtube cannot block ad blockers on, I would have tossed your browser a long time ago.
