I'm trying to migrate Thunderbird emails from a Vista laptop to a new Win 10 laptop. I have tried moving the Thunderbird/Profile folder following the instructions in "Moving Thunderbird Data to a New Computer" several times, and I think I'm getting the right folder(s) in the right place on the new computer, but when I start Thunderbird, the 'old' emails don't show up. Any help would be greatly appreiated.

Windows 10 quickbar icon corrupts on new firefox update

yet the icon i keep on my desktop stays fine. is it an issue with opening firefox and then pinning that icon? when the new version comes out, the old link is bad? been going on for a couple years. but now its just annoying.

I can't simply copy the icon from my desktop to the quickbar. Going to end up erasing the old icon, stopping the process.... opening a new firefox and pinning it again. but its only good until the next update. any ideas?

Hi , I try to setup mozilla.cfg to disable security exception message as the attachment, I try setup below:

'pref("browser.xul.error_pages.enabled", true); pref("security.ssl.enable_ocsp_stapling", false); pref("security.tls.insecure_fallback_hosts", "https://10.10.10.206"); pref("profile.accept_untrusted_certs", true); pref("security.insecure_field_warning.contextual.enabled", false);

But it still show message, how can I adjust? Thanks a lot.

Hello,

Even though I have an updated copy of Firefox, it still nags me to download "a fresh copy" because it failed o download. I had been plagued by this issue earlier and did download "the fresh copy" from FF's site, however the prompts don't go away. The troubleshooting info below.

Regardless of what version and CPU architecture of Thunderbird is installed, the auto updater keeps telling me that it cannot update Thunderbird and suggests that I visit Thunderbird's website to download the latest version.

Searches related to this problem all either involve Avast antivirus, which I am not using (I use F-Secure TOTAL) or very obsolete versions. To the best of my knowledge, I do not have any specific website blocked in my network, apart from Facebook, and despite searching, I cannot find out any debug options to determine the cause of the update failure.

I have tried uninstalling the product and reinstalling it, also changing between 32-bit and 64-bit versions. Currently running 78.9.1 64-bit under Windows in the Release channel.

Hi Mozilla Community Team, I want to know, how to use more than one Mozilla browser on one window to manage my all websites.

Kindly reply to me. Thanks!

I changed from email server to another. In the end, I had to backup my TBird profiles directory, uninstall TBird, delete Profiles, and install a new version of TBird. Don't ask.

When I started up TBird, I was (finally) able to configure it for the new server, and it got the emails that had queued up in the 3 hours it took me to get there (again, don't ask).

It was only after that that I noticed a dialog had popped up inviting me to choose a profile. On a whim, I restored the profile that has all my old mail in it and chose that one, and voila! my old emails are all still there, etc., and I'm up and running.

Now for my question. As I said, emails came in when I ran the program but before I changed over to the previous profile. In the previous profile, these emails do not appear, no surprise there. Is there any way to move them from their profile over to the one I really want to keep using?

TIA

My Firefox Dev Edition just updated to 89 b1 today. The screen was blank, the new tab button and no buttons are working. None of the menu items work except the About Firefox which just keeps showing the Restart To Update button. If I click it, it just loads the same blank page again and same issue. I uninstalled and downloaded b2 from the website and still same exact issues. I'm running macOS 11.3 RC which was released today.

When I try to turn Mozilla VPN on from my Android device, it goes thru a connection routine and switches to a confirming routine. It never completes and eventually returns to the VPN off screen. This process works correctly on my Windows device. Any suggestions?

Does anybody know where the ID: 308046B0AF4A39CB comes from?

If you use a Windows 10 1909 64 Bit and you can find this in the installs.ini and in the profiles.ini of users, if you have a Firefox ESR 64 Bit in Version 78.10.0 installed. The INI-Files looks like this:

Installs.ini: [308046B0AF4A39CB] Default=Profiles/8U9skky2.default-esr Locked=1

Profiles.ini: [Install308046B0AF4A39CB] Default=Profiles/8U9skky2.default-esr Locked=1

[Profile0] Name=default-esr IsRelative=1 Path=Profiles/8U9skky2.default-esr

[General] StartWithLastProfile=0 Version=2

This ID can vary if you have a 32 bit ESR-installation as well and the only place I could find it is in the registry

[HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\TaskBarIDs] C:\Program Files\Mozilla Firefox=308046B0AF4A39CB

But also here it differs sometimes.

I need to know where the ID comes from and if I can rely that if this ID is used, I will always address the Firefox ESR 64 Bit no matter which version.

I always have FF updates set on "Check for updates but let me choose to update them" after problems I and several others had several years ago with FF updates. Today it updated without asking me and now won't work with sandboxie and is acting weird.

I just switched from a Mac computer to a PC. My Mac Mail has about 15 years of emails in various folders within folders. I use this for my business, so it's a lot of emails. I tried to import the mbox files into Thunderbird from the auto-generated mboxes in the Library folder on my Mac computer, but when I did that, I got a series of subfolders within subfolders within subfolders named by numbers, not my folder names.

So, I tried a different method. I clicked on a main folder in my actual Mac Mail that contained sub-folders and clicked "export" and made sure to save it with its subfolders. I used the "Import/Export Tools Ng" importer add-on to import the main folder into my Thunderbird mail. However, it only imports the mail that was in the main folder. It does not bring over the subfolders (mboxes) with their mail.

I know there are a ton of importer tools out there, but I can't tell which ones will import the subfolders with their emails. I downloaded and tested a few of them on their trial versions, but none of them did what I wanted to.

Any help is MUCH appreciated!

Hi! More than a month ago, I realised that my firefox nightly version is few months old. It couldn't update itself, everytime I tried to use update function, after restarting browser it didn't udpate and it didn't even restart, just close itself. So I downloaded latest version from mozilla site to update. But now I remembered that moment and checked what version I have. Guess what, it's that version I downloaded back then. And I can't update it still. I don't know what the error is, but I know what it's connected to it. Every time I open firefox I have to open it double. First opening does literally nothing, and I have to open it 2nd time to open it.

Dear all,

on my McBook pro I had Thunderbird 78.8.1 installed. I saved my Mails per instruction onto my external disk. The saved directory looks like this: /Thunderbird/ImapMail /Thunderbird/ImapMail/imap.gmx.net /Thunderbird/ImapMail/imap.one.com /Thunderbird/Mail /Thunderbird/Mail/Local Folders /Thunderbird/Mail/pop3.web-1.de /Thunderbird/Mail/pop3.web-2.de /Thunderbird/Mail/pop3.web-3.de /Thunderbird/Mail/pop3.web.de

Then Apple reinstalled Big Sur from scratch. With a new user, I reinstalled Thunderbird -- this time I got V.78.9.0. I entered one of my three Mail-accounts as IMAP and closed Thunderbird. As per instruction, I copied the saved Thunderbird-data onto my internal hard disk into /Library/Thunderbird.

Actual results:

My stored mails from before the reinstallation are invisible. The other two Mail-accounts are invisible.

I added another one of my three Mail-accounts as POP3 and closed Thunderbird. As per instruction, I copied the saved Thunderbird-data onto my internal hard disk into /Library/Thunderbird.

My stored mails from before the reinstallation are still invisible. The other Mail-account is invisible.

Expected results:

I would like to access all my three Mail-accounts with the stored emails. At least I would like to get access to my stored Mail folders -- I can install the mail addresses newly, this is not my problem. After proceeding per instruction, I do not know why they are not accessible.

A very helpful person, Matt, showed me https://support.mozilla.org/en-US/questions/1315638#answer-1371097, where the same problem is solved. There it says:

  "Go to your backup and open whatever folder contains prefs.js."

In my backups is no prefs.js. To be exact, there is no prefs.js anywhere on my computer or on any of my backup disks. What can I do...? -- I can see my mails in the directory system. How can I access them?!

Thank you for your help in advance. N.
