I've imported/exported everything I could from a Win10 to a Win11 one. I then went to the toolbars under "view" and made sure they were all checked. Next, I clicked on "customize" and selected (single click) what I wanted to add to my toolbars in the mail window. The "save option" was greyed out. How do I save these to my toolbars?

The version I was using before could put have a layout like this with a simple tweak below: - Accounts - Individual email pane - Message list

I just CANNOT use Thunderbird if I can't do this. How do I do this in Nebula or what version can I revert to? Go to profile folder: Chrome folder userChrome css file Add this: /* puts message page in the middle */

Thunderbird crashed on me last night: "thunderbird killed by SIGSEGV"

The attached image shows that I'm being prompted for an API key. I'm not sure what that is or how to generate one (I presume unique to me?).

I believe I need one in order to file a bug. I can't seem to circumvent it.

Can anyone guide me in the right direction please?

Hello, I'm trying to setup a new email account using POP3 using the settings recommended by Privateemail and it does not work. Everything is fine if I use IMAP. But I really prefer POP3 I contacted them but can't identify the problem and asked me to revert to you. Can you please help, Thanks beforehand

Hello sfhowes,

Thank you for your response and I tried to follow your instructions. In one of the two accounts, I couldn't change POP mail server to IMAP mail server. I changed the Port to 993 but I couldn't change the Default to 993. Also, the outgoing SMTP server only appeared in the Default account, and not the other. I tried sending emails to both accounts, but the emails only appeared in the Sent folders and not the Inbox folders. The funny thing is that the emails appeared in the Inbox on my other computer! Will you be able to make the changes on this computer from your end? Once again, thank you so much for your help, and I look forward to hearing from you. Best regards, Sheila Herman

1. Recently, I'm not receiving any more new emails on this computer. What is causing this? Please help me solve this problem. 2. I just received a notification that Mozilla will shut down Pocket's services on July 8, 2025. I'm not sure that I utilize this service. Thank you and I look forward to hearing from you. Best regards, Sheila Herman

Firefox has been working fine, but today when I clicked to start, I received an error message. "The file or directory is corrupted or unreadable." When trying to uninstall Firefox, Windows cannot find the uninstall helper. When I try to download a new version, I receive an error message: "Couldn't download - virus scan failed." Windows Security reports are all good. A scan found no viruses. Firefox will not open at all.

After the 139.0 update, I noticed 'Firefox Labs' is missing on my settings page. I checked the config and saw: browser.preferences.experimental true

I have telemetry checked Send technical and interaction data to Mozilla This helps us improve Firefox features, performance, and stability. Learn more

Once in a while the 'Firefox Labs' will appear momentarily then disappear.

Any ideas son why this is happening?

Dear Firefox Support Team,

I hope this message finds you well.

My name is Mohammad Kamal Borojerde, and I’m experiencing serious ongoing security issues while using Firefox on my iPhone 13 Pro Max. I am a delivery driver working for Deliveroo, and my device is being targeted through remote hacking methods. I suspect that some malicious actors are using apps I’m not aware of to interfere with my internet, GPS location, and even stop delivery tasks that the company sends to my phone. This has significantly affected both my work and personal life.

Despite installing multiple security applications including McAfee (Reference No: 03203372) and Bitdefender (Reference No: 1010231778), my browsing remains unsecure, and settings keep getting changed or disabled without my consent. I believe attackers are also bypassing or disabling Firefox protections on my phone.

I kindly request Firefox’s security team to investigate this matter seriously. If possible, please help me: 1. Lock down or secure my Firefox browser fully. 2. Review any unusual activity linked to my device/browser. 3. Suggest any specific configuration settings that can protect me against remote access or phishing.

Here are my associated emails: Mod's note: PII removed

Thank you for your attention and assistance in this urgent matter.

Sincerely, Mohammad Kamal Borojerde

I just upgraded to Thurderbird V. 139, and my inbox looks completely different, which must have been part of this release intentionally, with every message summary now in an outlined rounded rect box, rather than beiung presented as a simple one line of table. Is there a way to go back to the old look? It let me see way more message summaries at one time, even when the new look is on high density. Thanks!

I have spent some time digging through your messages about how to fix this issue. I get the general "where to" enable SSL/TLS but no trouble shooting to this specific level.

Spectrum (charter) Internet on May-30-25 a pop up "Add Security Exception" on wife's account (Image #1 below). We have same Internet provider and same server config's (except email name & password or course).

 This Security Exception has happened before, as well as on my account in the past. 

Although, I never got the Exception this time. We did "Confirm Security Exception" 2x on her account and she is up and running again. No issues.

  However, I can't receive e-mails with the Account Settings / Server Settings / Security Settings

"Connection Security" set to SSL/TLS" it must be set to "None" When set to SSL/TLS and I push the "Get Mail" button, the server isn't even banged as there's no msg in lower left frame of TB. I have gmail account and it does bang that one like it should. If set to "None" I get the msg in lower left TB frame showing connection to Charter server and I receive any outstanding e-mails. But I don't want to continue without a password.

 Under [Settings/ Privacy & security / Manage Certificates]

hers (Image #2 below) looks different than mine (Image #3 below). She has the 2 confirmed Security Exceptions, but also has a "View" and "Export" button that are bolded when the specific line item is highlighted. I do not have a View or Export button shown. How do I enable the SSL/TLS with password and actually receive emails?

 I am using TB 128.11.0esr (64-bit)

thx in advance Gene

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

Luke

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

Until recently (like last week-ish) My Bookmarks Sidebar ONLY showed bookmarks. NOW, within the past few days the "bookmarks tools column" has been added to the screen-view. I have removed the 'tools' but the 'blank column' remains and takes up noticeable space on my laptop screen. How can I remove that 'column' ? Was this caused by a recent firefox update OR a win-365 'auto-update' ? Attached pic of screen - Here at the LEFT side is the 'blank column' with the 'settings Gear' at the bottom of the column. That is the column I want to 'Remove'.
