Dear Firefox.

I've now got 2 VPNs. One's called Proxy VeePN (that's how it spells it!) and the other one's your new one.

Proxy VeePN lets me use Pandora Music. Your one doesn't. Pandora can tell I'm in England on your one, it can't with Proxy VeePN (it thinks I'm in Switzerland, pretty sure.)

Why doesn't your one work with Pandora? I haven't tried it with anything else yet but then I really only use a VPN for Pandora Music anyway. Sometimes there's a couple of American games I play, but mainly Pandora. Why is it Proxy VeePN works with Pandora and yours doesn't?

Yours respectfully,

Chris, Windows 10 user cos I can't afford to buy a new computer that works with Windows 11 (I know there's a registry hack but I don't think this one's fast enough anyway, was designed for XP and tends to die a death with 10, let alone 11! Too slow. The computer, not its owner!)

Yours puzzledly,

Chris.

06 May 2026 USA Just to inform users:

All mailboxes and all mail in profile are catastrophically and irretrievably deleted when I: 1. Change the location of the profile folder. 2. Make appropriate change in profiles.ini reflecting the location change. 3. Launch Thunderbird in Offline Mode (launching in OFFLINE mode is the fatal event). 4. Mailboxes will appear during this one launched session

    but

5. If Thunderbird is closed while still OFFLINE, then a re-launch of Thunderbird in any state will reveal

     that all mailboxes and all mail have been deleted.

All mailboxes, and of course, all mail in the profile are catastrophically and irretrievably deleted. I was lucky that I made a backup before changing profile location.

The deletion of mail and mailboxes occur at the close of Thunderbird's OFFLINE state. An examination of the profile folder indicates the destruction has occurred upon closing of Thunderbird in OFFLINE state.

It is not the re-launch of Thunderbird that causes the catastrophic deletion. The deletion occurred when Thunderbird was closed in its OFFLINE state.

To successfully change the profile location I must: 1. Make the change to profile location. 2. Make the appropriate change to profiles.ini 3. BE SURE to make the FIRST LAUNCH of Thunderbird in ONLINE mode--ONLINE only. 4. Once 1,2,3 are done, then Thunderbird does not corrupt the profile folder.

Conditions that MIGHT make my configuration uniquely affected: 1. I use Proton Mail Bridge in conjunction with Thunderbird. 2. My Profile folder is on a network share that is letter-mapped in Windows. 3. I have about 10 email addresses in Thunderbird that are Outlook IMAP, Gmail IMAP, and of course, Proton Mail.

I've been using Thunderbird a couple of years in this configuration with no problems. I just decided to rename my profile. So, this is my first discovery of the problem.

送受信メールが表示されなくなりました。 テストメールの送受信は問題なくできていますが、thunderbirdメールソフトには表示されません。 XserverにWEBメールは生きています 表示されない問題を解決するためにAIに聞いたところ、「受信トレイ→右クリック→最適化」を実行したが、それまで表示されていた過去の受信メールがすべて消えました。 本体からメールが消えたのかAIに改めて聞いたところ、画像の「INBOX」の状態になり、消えてしまった可能性が大きいとの回答でした。 ウィルスバスターを導入しているので、それが干渉した可能性も考えられます

対策として「アカウントを削除して、新たに設定しダウンロードを提案されました。この方法で復活するでしょうか

I have moved my Thunderbird data from drive C:\xxx\Thunderbird to N:\xxx\Thunderbird. The Thunderbird program remains on "C:\Program Files\Mozilla Thunderbird" How do I tell Thunderbird to find its data on the N: drive?

     Thank you,    Art Lieberman

Good morning. I’m trying to set up a new email account for my Xbox gaming system in Outlook. It’s currently in Thunderbird, but it’s for Outlook, and it keeps saying the password and email address can’t be verified. I don’t know of any login, and I’m sure the password and email address are correct. Any ideas?

The latest version of Firefox 150.0.1 (64 bit) does not work correctly for Twitch.tv and Canadiantire.ca. I can't login to either. Is anyone else having similar problems?

First of all, I thank the great volunteers that have structured this great browser- Mozilla Firefox despite the persecutions from the giant Microsoft. I love Mozilla Firefox and I support it. I am of those who wrote petitions against Microsoft for undue negative manipulation of Mozilla Firefox. My petitions went to the European Union, Federal Trade Center, Independent Press Organization etc. The issue of my complaint about Mozilla Firefox is the non-functionality of Mozilla Firefox's Bookmark and History: The bookmark and History has had problem for a long-time. Most people who use Firefox admire the Bookmark and History. Once you open your computer window, on the left of the window, there is a list of your bookmark and you do not struggle to search for your favorite bookmark as in Microsoft Edge or Google It is there on your left. It is the gold standard of structuring a browser. No browser can compete with Mozilla Firefox in this respect. This is the reason Mozilla Firefox remains one of the best browsers ever. If it is Microsoft or any other group, they would have rushed to mend this defect. I know that Mozilla is made up of volunteers. Could any of the engineering volunteers see what I am saying?

After the latest update to Firefox for iOS, I can't open pages with an untrusted SSL certificate. It's a blank page. There's no threat prompt that I can accept to proceed (as before). I use Firefox for iOS primarily to log in to Ubiquiti devices on the local network (address: 192.168.x.x). Everything worked fine until recently. Now it doesn't. I cleared the browser cache, disabled security, and that didn't help. I uninstalled and reinstalled the browser, and that didn't help either. Other iOS browsers (e.g., Brave and Safari) work fine—the untrusted certificate prompt appears, and after accepting the threat, the login screen appears. Please help.

Every time I go to the message screen and then back to the page I sign in on another page starts. I end up with many pages that I don’t want. How do I stop this from happening?

Before the update, I could use "cmd+shift+[number]" to open a new container tab. Now, nothing works. "cmd+t" opens a tab with "no container", which is completely different.

I already tried going to "about:keyboard", but opening a new container tab isn't even listed as an option.

I am trying to re-install THUNDERBIRD I have done this several times before but Google is causing problems When I reenter my Name email address and password Thunderbird finds the email but then it takes me to google and I have to click allow but then it takes me back to the email install and then tells me it cannot find the Email address with the settings

THE SAME SETTINGS IN FOUND 1 MINUTE EARLIER

I have 2 email addresses and it does the same with both so Thunderbird does not now work on a Computer that I have used Thunderbird for Years

Anyone else had problems the last two weeks with performance? I'm on a macbook (Tahoe 26.3.1) and in the last two weeks tabs are constantly crashing or freezing. I have never had this before. It's doing my head in and I'm about to make the painful move over to Chrome if nobody has any ideas how to fix it?! I don't want to do that as all my bookmarks etc are set up on Firefox...

As a die-hard fan of Mozilla products for many years, I genuinely want to say thank you to the Thunderbird team for keeping such an amazing open-source project alive and improving it continuously. Thunderbird is still one of the most trusted and powerful email clients ever made, and many of us truly love using it every single day.

But from the bottom of my heart, there is one feature I strongly feel Thunderbird now urgently needs.

Please give Thunderbird a complete Mozilla Account–based sync system, just like Firefox.

Today, whenever we shift to a new computer, we still have to manually:

• reinstall extensions
• reconfigure settings
• restore filters
• restore signatures
• adjust preferences again
• rebuild our personalized setup

For long-time Thunderbird users, this takes a lot of time and effort.

Firefox already gives us such a beautiful and worry-free experience:

• Install Firefox
• Login with Mozilla Account
• Everything comes back automatically

And honestly… that experience feels magical.

As Thunderbird users, we dream of the same simplicity:

• Install Thunderbird
• Login with Mozilla Account
• Extensions auto-install
• Settings sync automatically
• Filters & signatures restore instantly
• Everything feels exactly like our old computer

No stress. No manual setup. No fear of migration.

This is not just a “feature request.” For many loyal Mozilla users, this would be one of the biggest quality-of-life improvements Thunderbird could ever receive.

The Thunderbird team has already discussed this idea publicly for years, which gives users hope that someday it may finally happen.

Please make Thunderbird truly cloud-connected and worry-free for the next generation of users.

Many of us are not just users of Mozilla products — we are emotionally connected to them. ❤

I keep getting this message at the top of each site I go to: "You must log in to this network before you can access the Internet" It thinks I'm on a captive portal?? I'm at home on my own internet network. Why am I getting this message?
