I had this trouble after Firefox's previous update, where the browser would just close as I was in a tab. It had stopped so I thought the problem was fixed. However, it just updated the browser a few days ago and again I'm having a problem where the browser will just close in the middle of me entering information. It does not have to do with which program I am in as it just seems to happen randomly. It does not save any information I've typed in.

I'm using gmail/outlook/hotmail email addresses on a new win11 laptop with Surfshark VPN and getting email up & running is the last major set up issue. I am having issues with both send & receive emails across all addresses. I get some functionality if I pause the VPN (not ideal!) but not total. I have tried the Surfshark bypass function for Thunderbird but without success.

I have had no issues with this setup for many years on win10.

Using Outlook (one email address) on the web with the Surfshark Chrome extension I can both send & receive.

1. what should the IMAP & SMTP server settings be for gmail/outlook/hotmail? 2. are there any known issues with Thunderbird/Surfshark? 3. are you aware of any issues with gmail/outlook/hotmail blocking Surfsahrk?

So for three days now, my firefox constantly crashes. I would be reading a story online or watching a video on Youtube and then it will suddenly freeze. In videos, it'll still play the sound but the screen will freeze. I can't pause or stop it. Then either Firefox crashes and closes or I have to close it for it to stop. Sometimes, when I try opening it again, it still won't open. I used to have 50 tabs open and never ad this issue. After this, I closed all the open tabs, even deactivated a bunch of extensions, run malware detection, and still the issue continues. I don't know what the problem is. I even followed instructions and deactivated hardware acceleration options in Performance. And I have all AI options turned off too. The app also recently was updated.

Before asking my question, I have to say that I have been extremely happy that Thunderbird introduced their app. for phones. Historically, I have had many problems with my desktop version, and even now there are days that I cannot send e-mails from my desktop, but that's a question for another time.

My question now is, am I somehow able to access my local folders that my son set up on my desktop (in order not to clog up my allowance), on my phone? The local folders are in the menu on my desktop, but not on my phone.

ok now every time Firefox updates im on a a page and yes i do have ad ons or extensions which Firefox offers and if we are not supposed to use the why offer them Ill be on a page mostly A Facebook page and it keeps asking me to stay on or leave page on Facebook page stay on page or leave page I try to hit stay on page and i can not i have have to ht leave page what is going on and why i hate this thing why do i have to keep refreshing the page why is this happening do i need to remove the add on you support this is just not right

Malwarebytes is picking up and blocking an outbound connection request from Firefox - www.highperformance.com. Anyone else experiencing this?

Thunderbird 148+ on Windows 11 repeatedly prompts for the password when synchronizing an Exchange account (professional) configured with the native Exchange support (no add-on installed).

The account only offers “NTLM” or “Normal password” authentication methods. OAuth2 is not available in the account settings.

During synchronization, Thunderbird asks for the password separately for many folders. However, clicking “Retry” usually works immediately without changing the password, and manually re-entering the same password also works.

The issue then reappears for the next folder, causing continuous authentication prompts (I have many folders...).

Actions already tested:

• deleting saved passwords and tokens,
• deleting/renaming key4.db and logins.json,
• restarting Thunderbird,
• recreating the account.

The problem persists.

This looks like an authentication/session handling issue rather than an actual invalid password.

I have Firebird Beta installed. I also have Outlook 2019 but after an update the address book is not visible. I have located the pst file(s) but don't know how to import the email address book from Outlook to Firebird Beta. Can you help?

I've recently switched to Firefox but am finding some of the performance a bit cumbersome. I am continually being asked to hit "Send" ["To display this page, Firefox must send information ..."] when I am logging into my Outlook email or looking at my bank information. I'd rather not be "resending" these pages each time and am wondering if there is a setting.

Thanks, Nancy

I have the latest version 151.0.2 (64-bit), always update. It's terribly buggy now out of nowhere. Tabs won't connect to the internet after laptop wakes from sleep. All other browsers still do. If I close FF and reopen I lose ALL my tabs even though for decades I've had it set to reopen all tabs. What's up?

I am moving my Thunderbird (32 bit) data from an old Win 7 computer to Linux Mint on a new machine with Thunderbird 64 bit. I have followed all the advice to copy the old computer profile to the profile folder in Mint, but nothing appears in Thunderbird. My pop3 email server has 2-factor authentication; I can set this up and access or send new emails, but I can't import all my old email folders. The old Thunderbird is version 115.18.0 (32 bit) and says it is "up to date on esr update channel" The Mint Thunderbird is 140.0.6 esr (64 bit) and was recently installed with Mint.

As these versions are 32 bit and 64 bit respectively, I don't see how I can make them the same version, as recommended for transferring profiles.

How can I make this work?

I've been seeing a doubling of *some* incoming messages, where a duplicate message comes very soon after the first one. For example, two incoming messages were received at:

Sun, 07 Jun 2026 14:03:10 +0000

Sun, 07 Jun 2026 14:04:31 +0000

So the second message came in about 1 minute and 21 seconds after the first, and not because of anything I did (as far as I know). But then that was it, no third message came in.

This isn't really a bug, as nothing is harmed, just a repeated message. Any thoughts would be appreciated.

I had to reload firefox after getting xpcom error messages, now i can't work out how to restore my passwords,bookmarks etc from my sync profile that i set up months before.

I have successfully set up 3 email accounts using my default domain. When I try to use an email account that uses a second domain I can't send or receive emails. This account required manual setup which I did but it does not work. My web hosting is with Namecheap and I do believe settings at that end are correct. Any help would be appreciated.
