Thunderbird Support Forum

I have used Thunderbird for more than 15 years and have always liked the way it works and promote it to anyone needing an email client, but the latest version 115 Super Nova is terrible. I don't like the font or anything in the update. Now I just found a new problem. Since last update messages show all previous messages from same sender with current message at the bottom of list. I have looked for a way to change this but have not found anything. It used to work so good and now it sucks.

Hallo, Ik gebruik 2 verschillende gmail-adressen in Thunderbird. Met het ene adres heb ik geen probleem, met het andere krijg ik steeds de melding "Authentificatiefout tijdens het verbinden met server imap.gmail.com". De serverinstellingen in de accountinstellingen in beide adressen zijn identiek. Hoe los ik dit op? Bedankt voor uw reactie.

bold text4 or 5 years ago i simply synced TB and Firefox straight to my laptop from my desktop. Today it does not seem to work that way. Why has it gotten more complicated? I have all of my emails, address's and etc.saved profile and cannot seem to replace it. I tried the thunderbird.exe -p and it gets confusing there. Apparently it does not give one the option to replace profile like mine, but one can create one. I tried creating by entering my old Profile and it did not work. It says to use the Browse button which should bring you to the actual spot to add your profile. I do not see a 'Browser" button, but do see 2 separate folders buttons, but i do not know which to choose, if any. I have donated in the past when things were working smoothly, but discourged to add to it now with all these upgrade mess's. Like they say, "if it ain't broken, leave it alone..." s amd

I created a signature years ago. With the last Thunderbird update, the signature font (and image) shrunk in size. I would like the signature to match the font size of the message text, like it used to. I can't find any information about that, or any explanation as to why it shrunk.

I am a longtime Thunderbird user, currently running 115.6.0 (32-bit). Very recently Windows Defender is detecting malware it identifies as Trojan:HTML/Phish!pz. Defender is unable to quarantine or eliminate the threat.

The specific file is appearing in Volume Shadow Copy data when I am running backup: file: \Device\HarddiskVolumeShadowCopy55\Users\fhanz\AppData\Local\Thunderbird\Profiles\sootdszw.default-release\cache2\entries\342F92977A0BA0715CB8880A9289BC8F8827262C

I've attempted several times to remove the offending file(s), but the problem returns.

What is the best method to determine the source of this malware and effectively eliminate it returning?

If it matters, I use Chrome as my default browser.

Suddenly, I can't send email from my Thunderbird (115.6.1 (64 Bit)) Windows app. Spectrum is my email provider. I can receive email just fine. However, when I respond to an email and when I send a newly created email or replying to a receive email, I get the following error message - " Sending of the message failed. An error occurred while sending mail. The mail server responded: <[edited] @tx.rr.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again."

I've been using Spectrum and Thunderbird for many-many years. This problem is going to cost me big-time if not resolved soon. I love THUNDERBIRD!

Please help!

Hello, Experts:

First up, I'm a happy user of Thunderbird with some years of experience. I make use of filters, and up until about 2 weeks ago they all worked. Now two of my filters (not all) have stopped working automatically, and I have to go to Tools/Message Filters and run them manually.

I'm on TB 102.15.1.

I have deleted the non-working filters and re-created them. No change in behavior.

I would NOT like to de-install/re-install TB because it's a good deal of work, and TB is a critical system for me.

That said, I keep a laptop computer for travel, and the filters work on that platform. IS THERE A WAY to copy a file or folder over from the working laptop onto my desktop machine, where the filters have failed?

Thanks in advance, Bob

I had a crash on my desktop PC, possibly due to an erroneous action of mine, which occurred on December 20th, which has ended with my PC, which after entering the password, the screen locks to black.

I turned to my laptop as a salvation, but when I tried to open my email, for which I use Mozilla Thunderbird, at first I opened the home page, but my email accounts did not appear. Currently, it doesn't even open that page when you tap on that desktop icon.

I'm an 80-year-old male and I'm getting more and more clumsy with the SW of the PC, so I pray that if you can help me it's in a language for the very clumsy in computer matters. I don't speak English so this is automatically translated, so I would appreciate it if you could help me in Spanish to restore my email accounts, since I am no longer used to using Web mail.

My PC is an HP Pavilion x360 -14-cd0018ns, I5 core 8th Gen. / W10 home/ HD ext. 3TB for data.

Thanks a lot. PLOK.

After decades of using Thunderbird it has amassed contacts. Even for my own contact it saves a contact like "lynn@szetosolutions". incomplete email addresses, or associated with DMV...just for my own email it has saved 7 versions and or affiliations. I want to clean up and remove the excess, inaccurate email addresses that keep auto filling my emails and reduce the constant annoyance. Can someone help me? I'm so grateful for any help.

up until a few months ago, Thunderbird opened jpg/jpeg images inline, that is in the message window. Instead I get an empty white box where the image SHOULD have displayed. The only option now available appears to open the attached image with PHOTOS which takes longer as Thunderbird has to call photos to load the image. Also it takes longer to actually display the image. So what happened?

My current work-around to this issue is to drag/drop the attached image to my photo editor which loads rather quickly. Much faster than photos.

Mozilla has done it again. They seem to be on a mission to ruin their programs. I have already switched away from FireFox, and now I will have to switch away from Thunderbird if I can't downgrade.

I foolishly upgraded to 115.5.1. The new interface is more cluttered and takes up about 30% more space than the old interface. The bar at the top is wider, the bar between the email list and the email contents is wider. The side bar on the left which lists the folders is wider. And all this is happening even though I have "density" set to maximum. Furthermore, my favorite add-on is suddenly no longer working and I can't find a way to restart it.

What I need is this:

• Please tell me which version prior to 115.5.1 is the most stable and doesn't have any of the interface changes that 115.5.1 has. (How do I find out the number of the last version I was using?)

• Please give me detailed instructions on how to download such version and downgrade. I am NOT a computer person and I need clear instructions.

Thank you.

I've got a long-standing email account that will be closing in a month and I need to keep all the emails on it... I'm not technical! Are they kept on my laptop, or just on the server? If the latter how does someone who's not technical go about getting them local, and also able to access them again through Thunderbird ideally? I've tried to look at old posts but they are quite technical generally so I'm looking for a bit of hand-holding/easy instructions :)

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

Hello, All

I need major help, please.

I am getting the attached messages when trying to send an email. Thunderbird worked perfectly yesterday morning, but then would not send any emails. I get emails, but cannot send from my 2 accounts.

I am on the latest version of Thunderbird, Supernova 115.10.1

Also, I cannot find out where to change my password for the accounts, because at times I need to fill in a password. I can't find it.

Thanks in advance for any help.

Best, Leslie
