Firefox and Thunderbird are built using Mozilla's Release Automation infrastructure. On Mac OS X, part of this infrastructure is automatic signing of the '.app' folder using Apple's codesign tool. For projects that don't use Mozilla's Release Automation and would like to be signed for secure launching on OS 10.8 Mountain Lion and later, this guide should provide some insight into how to make.

• Who makes Thunderbird? See Help-About Mozilla Thunderbird, and click the 'global community' for a list of some of the people who have contributed to Thunderbird. Where's the Thunderbird source code? A tarball of the Thunderbird source code is available for download. The latest development code can be obtained by Mercurial.
• A Finder window appears, containing the Thunderbird application. Drag the Thunderbird icon to the Applications folder. Now eject the disk image by selecting it in a Finder window and pressing the command + E keys or by using the Finder's File menu, and selecting Eject.

You can connect Mozilla Thunderbird 8.0 to your email account using POP3 or IMAP4 connectivity. These instructions apply to Windows and Mac.

Set up email using Mozilla Thunderbird 8.0

1. Open Mozilla Thunderbird. The Mail Account Setup dialog box will open the first time that you open Thunderbird. If the Mail Account Setup dialog box doesn't open, do the following:

   1. On the Tools menu, click Account Settings.

   2. On the Account Settings page, under Account Actions, click Add Mail Account.

2. In the Mail Account Setup dialog box, do the following:

   1. In the Your Name box, enter the name that you want to appear on the 'From' line in your outgoing messages.

   2. In the Email Address box, enter your email address.

   3. In the Password box, enter your password. Click Continue if you're using a Windows computer or click Next if you're using a Mac. Thunderbird will try to find the settings you need to configure for your account.

3. Click Stop, or wait for Thunderbird to try to find your account settings. You’ll see the message: 'Thunderbird failed to find the settings for your email account.'

4. The IMAP check box, next to Incoming, is selected by default and is recommended. In the Server hostname box, enter the name of your incoming server. If you’re connecting to your Microsoft 365 email, the IMAP or POP server name is partner.outlook.cn. If you’re not using Microsoft 365, see Find your POP3 and IMAP server settings later in this article.

   Free video format converters for mac. Note: Leave the Port option set to Auto. Leave the SSL and Authentication options set to Autodetect.

5. In the Server hostname text box, next to Outgoing, enter your SMTP server name. If you’re connecting to your Microsoft 365 email, the SMTP server name is smtp.office365.cn. If you’re not using Microsoft 365, see Find your POP3 and IMAP server settings later in this article.

   Note: Leave the Port option set to Auto. Leave the SSL and Authentication options set to Autodetect.

6. In the Username box, type your complete email address. For example, tonysmith@contoso.cn.

7. Click the Re-test button. If you see the message 'The following settings were found by probing the given server,” click Create Account. A page opens that lets you view or change other Thunderbird settings.

   Click OK when you've finished viewing or changing the settings. If you’re unable to connect, see “What else do I need know?” later in this topic.

   Note: If you're using POP, under Server Settings, it's a good idea to select Leave messages on the server. After you select this check box, a copy of the messages you retrieve to your local computer will be kept on the server. You’ll also be able to access your messages from a different mail application.

Find your POP or IMAP server settings

Cd device for mac. If you’re connecting to your Microsoft 365 email, you don’t need to look up your settings. For Microsoft 365, the server name for IMAP and POP is partner.outlook.cn and the server name for SMTP is smtp.office365.cn.

If you’re not connecting to Microsoft 365 email, do the following to look up your settings.

1. Sign in to your account using Outlook Web App.

2. In Outlook Web App, on the toolbar, click Settings > Options > Account > My account > Settings for POP or IMAP access.

3. Best linux os for mac. The POP3, IMAP4, and SMTP server name and other settings you may need to enter are listed on the Settings for POP and IMAP Access page under POP setting or IMAP setting, and SMTP setting.

What else do I need to know?

• If you don't know whether to use POP3 or IMAP4, consider using IMAP4 because it supports more features.

• If your email account is the type that requires registration, you must register it the first time you sign in to Outlook Web App. Connecting to your email account through POP3 or IMAP4 will fail if you haven't registered your account through Outlook Web App. After you sign in to your account, sign out. Then try to connect using your POP3 or IMAP4 program.

• If you’re using an incoming POP3 server, you can only synchronize your Inbox folder. If you’re using IMAP4, you can choose the folders that you want Thunderbird to synchronize with the server. Remember that IMAP4 doesn’t support the synchronization of the Contacts and Calendar folders. Thunderbird uses a folder named Sent to store sent items. Exchange and Outlook Web App use a folder named Sent Items. You can synchronize the email items that you’ve sent in Thunderbird with the Sent Items folder on the Exchange server. To do this, follow these steps:

• In Thunderbird, in the console tree, select your email account. In the details pane, under Advanced, click Manage Folder Subscriptions. In the Subscribe dialog box, select the Sent Items check box, and then click OK.

• In Thunderbird, on the Tools menu, click Account Settings.

• In the navigation pane of Account Settings, select Copies & Folders for your email account.

• In the details pane, under When sending messages, automatically, select Other. In the drop-down list, select your user name, select Sent Items, and then click OK.

Downloading

Mozilla Thunderbird For Windows 10 64 Bit

Mozilla provides Thunderbird for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Thunderbird here.

For builds for other systems and languages not provided by Mozilla.org, see the Contributed Builds section at the end of this document.

Installing

Thunderbird For Mac Reviews

Please note that installing a new version of Thunderbird will overwrite your existing installation of Thunderbird. For all systems, you won't lose any of your messages or address books, but some of your extensions and other add-ons might not work until they are updated by the author.

Uninstalling

Mozilla Thunderbird 64 Bit

You can remove Thunderbird through the Control Panel in the Start Menu on Windows, by removing the Thunderbird application on OS X, or by removing the thunderbird folder on Linux.

Removing Thunderbird won't remove your emails or newsgroup messages. This data is stored in your profile folder, which is located in one of the following locations depending on your operating system:

Any version of Thunderbird that you install after removing Thunderbird will continue to use the data from this profile folder.

Extensions and Themes

Mozilla Thunderbird Portable Mac

Extensions installed under previous versions of Thunderbird may be incompatible and/or require updates to work with Thunderbird. Please report any issues to the maintainer of the extension.

When you install Thunderbird all of your Extensions and Themes will be disabled until Thunderbird determines that either a) they are compatible with this release or b) there are newer versions available that are compatible.

Known Issues

This list covers some of the known problems with Thunderbird. Please read this before reporting any new bugs.

• If you are unable to view content for your RSS feeds in the Wide View Layout, you may need to disable the Lightning Calendar add-on if you have it installed or switch to Classic View and restart Thunderbird. (Bug 531397)

Troubleshooting

• Poorly designed or incompatible extensions can cause problems with your email client, including make it crash, slow down message display, etc. If you encounter strange problems relating to parts of the email client no longer working, the email client not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble.
  Restart the email client in Safe Mode - select Help followed by Restart with Add-ons disabled. When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
• If you encounter strange problems relating to email, feeds or newsgroup messages, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running Thunderbird with the -P command line argument, choose the 'Manage Profiles' button and then choose 'Create Profile..'. Migrate your settings files (Emails, feeds, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file, being sure to remove any private information as necessary.
