My isp is virgin media and I use Mozilla for browsing and emails. I have been with them for many years but recently I found that although I am receiving emails I can't send them . I get this message.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Authentication Required (VM401). Please verify that your email address is correct in your account settings and try again.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

Hi,

It's been a while since this problem first occurred but I am now very sure that this is about Firefox and not about graphics driver. This happens both when the hardware acceleration is turned on and turned off.

When I open a website that has mainly images or videos, the browser goes blitz (Reddit, Twitch, etc.). Screen splits to multiple views, it starts flickering and continues until I switch to another tab or quit Firefox. For flickering to stop, I need to restart the computer. I can also send a video if you can communicate a proper way of sharing. (Drive link, youtube, etc.)

Is there any way I can ensure Firefox does not break things on my computer?

Thanks

I installed the latest Thunderbird program and installed successfully on Windows 10 PC. The Inbox emails imported okay but the sent emails, draft and all other folders are not importing from Gmail. Help please !

I am with Telstra ( Australia ) Bigpond internet with saved passwords which following recent ( Thunderbird) update Thunderbird cannot connect to the server. I have not changed any settings or passwords prior to this error see attached for error I am also a donor to Thunderbird.

HelIo the Firefox team, I use Mackbook Pro, while Firefox is my favorite browser. Recently, I encounter an unpleasant and annoying SPONTANEOUS zoom-in and out in pages. It makes browsing impossible and prompts me to go for another browser. May it be a virus? How to solve this? It's really intolerable. Thank you in advance. Yigal.

Starting about 8/12/24 (2 days ago) I ran Malwarebytes. Now my Thunderbird is not capturing most of my yahoo mail. I still get some emails, but no emails sent out to large groups (that include me).

How can I troubleshoot this? How can I fix this?

Thank you!

For the past couple of months, every time I boot up my computer and launch Thunderbird I get the attached error messages for each of my email accounts (2 Hotmail and one Outlook)

Repeatedly clicking "retry" often results in success but sometimes I get the second message indicating the server has disconnected. Usually, after a few minutes things settle down, the messages come through and all is well but it is a nuisance. I would switch to using Outlook but it cannot send multiple emails which I periodically need to do and I don't want to encourage Microsoft's near monopoly of computer technology.

I have tried accepting coookies as advised elsewhere in here and tried turning on O Oath as my authentication method but this just got me another error message saying this authentication "was not supported on this platform" (whatever that means??) Anyway, I reverted to using "simple password" which does eventually work.

I looked at 2 factor authentication but that proved to be impossible to understand and, in any case, I rarely carry a 'phone with me and do not want to clutter my 'phone up with more apps. I use 2 factor authentication on a lot of my confidential accounts and none of these were as complicated to set up as this one and certainly did not invole scanning QR codes and installing special apps.

Will this bug be fixed by more updates to Thunderbird or is there some other way of solving this problem.

A week ago my whole computer went kaput. I pay for cloud back-up so everything except Thunderbird was fully restored. I know noting about computers. My friend, an IT pro who built and sold me this machine, has worked hard without success. This is my home desktop machine running Windows 10. I can access incoming mail through AT&T Yahoo Mail. And today some kind AT&T person spent two hours with me on the phone. Now I have a newly assigned security code and, to my surprise, a functioning Thunderbird. However, my hundreds of addresses have not reappeared nor have the thousands of saved emails in my various local folders. I believe what I have now is a newer version of Thunderbird. Much of it looks different. And weirdly there was a button for "old email" that I hit and started to receive things sent to me as far back as 2007. I think it stopped at some capacity limit. I am sure most of what came through I don't want but I certainly don't want to permanently delete things I may have moved to another folder. The AT&T person got me to some repair page with step-by-step instructions for hooking up with Thunderbird but he got stymied at some point. I am at a loss here and would appreciate help. Thank you for your time and attention.

I use Private Browsing to read a newspaper, not behind a paywall, for the main reason it hides all the adds. But just this last few weeks I keep getting the message "Please allow ads on out site" more and more not a great problem I just refresh the page and like magic gone. I like to open each story in a new tab so when I have read the paper I can have a whole lot of tabs all with just one story so after I read the story I close the tab and still have the paper opened where I left off for quicker navigation in its original tab. I do not have an Ad Blocked running in Private Browsing mode but as you can see the site thinks I am. Is there anything that can prevent this from happening? see attached.

Many thanks.

If I configure DoH in Windows 11, Firefox is unable to make any name lookups.

Originally I had DoH configured in Firefox, I wanted to use a Custom provider so I entered the details, and this worked initially.

I then configured the Windows 11 OS itself with the DoH custom provider, and this also worked in other apps, I could also use nslookup to successfully perform name lookups.

However, after configuring DoH in the OS, when I returned to Firefox, I could no longer access any websites. If I reconfigured Firefox to use CloudFlare or NextDNS with DoH, they also would not work. If I disabled DoH in Firefox and used regular DNS, Firefox was still incapable of performing any name lookups and accessing any websites. Only when disabling DoH in the OS did Firefox begin working normally again. I re-enabled my custom DoH in Firefox and it works as long as I do not enable DoH at the OS level.

Is this a bug?

Firefox 129.0.1 (64-bit)

Thunderbird used to have a panel on the left-hand side of the screen which listed folders such as bin, sent, etc etc. This has disappeared and I do not know how to access folders such as bin, sent, trash, important etc.

Hi

I hope someone can provide me with some advice.

I have used Thunderbird since its birth and have always found it reliable. However the latest release seems to be having problems with moving emails.

Example 1 - I moved an email from my Inbox to a special folder. The email was present in full before the move. Only the header appeared to be copied. I could not undo this and attempting repair on both inbox and other folder failed, as did exit and re-start. The result is that this email is lost.

Example 2 - I went to do a bulk move from the search window (something I have done hundreds of times before without incident). As usual CTRL A, Move to <new folder>, emails greyed out but nothing happens. Exit, return, repeat - same result.

At other times, both these type of operations work fine. But it is unpredictable.

Relatedly, I observe that on start-up the Inbox initially shows as <no messages> and takes several seconds to populate. Also, my auto-filing Rules are also working inconsistently.

These two points, and the two examples, are new issues for me since 128 release. I am using Windows 10 Pro on an HP Envy 17" laptop.

Any suggestions welcome as I am now concerned about losing emails!

Best wishes Roland

Incoming emails go to my "all mail" folder instead of to my "Inbox" on top. When I try to erase any emails, a line goes thru the email, but it does not go to "trash" as they used to. Nothing seems to get them to "trash"; my system is clogged with huge #s of deleted emails; driving me nuts!!! HELP PLEASE!!!!

When I search for anything using "Search Messages" (Ctrl+Shift+F) it takes forever - like up to half an hour!!! Even if the search criteria is "Subject contains" [textstring], or "Date is" [today's date] - which used to take seconds. It seems as if it's stopped indexing my emails.

Any idea how to fix this?

I'm using TB 115.12.2 and Windows 10.

Many thanks
