I have suddenly lost internet access using my Firefox browser. Have been using it for years, and as a senior, non-techie, I don't know what to do. I would like to have a live person talk me through what to do. I am using a Mac BookAir macOSMonterey 12.7.6

Here is a complete **A–Z guide** for setting up an email account in **Mozilla Thunderbird**:

---

1. 1. 🦅 Mozilla Thunderbird — Complete Email Account Setup (A to Z)

---

1. 1. 1. **A — Open Thunderbird & Access Account Settings**

Launch Mozilla Thunderbird. For a new install, you will be automatically prompted to enter your existing email account details upon first launch. For an existing install, navigate via **☰ Menu → New Account → Existing Email**. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

---

1. 1. 1. **B — Gather Required Information First**

Before starting, have ready: - Your **full email address** (e.g., you@example.com) - Your **password** - Your **incoming server** (IMAP or POP3) hostname & port - Your **outgoing server** (SMTP) hostname & port - **SSL/TLS** or **STARTTLS** encryption type

These details can be supplied by your email provider. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **C — Add a New Mail Account**

At the bottom of the left pane in Account Settings, click the **Account Actions** button and select **Add Mail Account…** [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **D — Enter Basic Account Details**

In the Mail Account Setup dialog box: - **Your Name** — the name that appears on the "From" line in outgoing messages - **Email Address** — your full email address - **Password** — your email account password [Microsoft Support](https://support.microsoft.com/en-us/topic/set-up-email-in-mozilla-thunderbird-8-0-f4726a9e-64d3-4494-9260-5762597fd1a6)

---

1. 1. 1. **E — Auto-Configuration Attempt**

Click **Continue**. Thunderbird will check if your webmail provider is available in its database and provide available configuration options. IMAP will be the preferred setting in most cases. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

---

1. 1. 1. **F — Manual Configuration (if needed)**

If auto-detection fails or you have a non-standard configuration, press **Manual Configuration** and edit the server names, ports, and IMAP/POP settings manually. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **G — Choose Incoming Protocol: IMAP vs POP3**

IMAP (the more modern protocol) allows you to store messages on the mail server and on your local machine at the same time. The POP protocol only allows messages to be stored locally. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

Common IMAP settings: | Field | Value | |---|---| | Protocol | IMAP | | Port | 993 | | SSL | SSL/TLS |

Common POP3 settings: | Field | Value | |---|---| | Protocol | POP3 | | Port | 995 | | SSL | SSL/TLS |

---

1. 1. 1. **H — Configure Outgoing (SMTP) Server**

In the Server hostname text box next to **Outgoing**, enter your SMTP server name. [Microsoft Support](https://support.microsoft.com/en-us/topic/set-up-email-in-mozilla-thunderbird-8-0-f4726a9e-64d3-4494-9260-5762597fd1a6)

Common SMTP settings: | Field | Value | |---|---| | Port | 465 (SSL) or 587 (STARTTLS) | | Authentication | Normal password or OAuth2 |

---

1. 1. 1. **I — Set Username**

Set the username to your **full email address** (e.g., username@yourdomain.com). [SiteGround](https://www.siteground.com/tutorials/email/mozilla-thunderbird/)

---

1. 1. 1. **J — Test Your Settings**

Click **Re-test** to test your manual settings; there should be a quick response indicating the settings are valid. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **K — Authentication Method**

For modern providers like Gmail, Outlook, Yahoo, and AOL, **OAuth2** is used. An OAuth2 window may pop up for modern Outlook accounts — approve the permissions when prompted. [TechyDen](https://techyden.com/thunderbird-email-client-configuration/)

For app passwords (e.g., with 2FA enabled): Go to your Microsoft Account Security settings, find **App passwords** under "Additional security," generate one, and use it in Thunderbird instead of your regular password. [TechyDen](https://techyden.com/thunderbird-email-client-configuration/)

---

1. 1. 1. **L — Complete Account Creation**

Once you have selected your protocol, click **Done**. Thunderbird will begin to retrieve your folders and messages from your provider — a progress bar will be visible in the lower right of your screen. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

---

---

1. 1. 1. **O — POP3 Tip: Keep Messages on Server**

If using a POP3 incoming server, it's a good idea to select **Leave messages on the server** so a copy of retrieved messages is kept on the server and accessible from other email applications. [Microsoft Support](https://support.microsoft.com/en-us/topic/set-up-email-in-mozilla-thunderbird-8-0-f4726a9e-64d3-4494-9260-5762597fd1a6)

---

1. 1. 1. **T — Multiple Identities per Account**

In Thunderbird, you can set up more than one identity per account. Click **Manage Identities** to set up and manage additional identities — each with its own name, address, signature, and outgoing server. [Mozilla Support](https://support.mozilla.org/en-US/kb/configuration-options-accounts)

---

1. 1. 1. **U — Multiple Outgoing (SMTP) Servers**

If you have multiple outgoing servers set up, use the **Outgoing Server** menu to choose which server to use with each identity. [Mozilla Support](https://support.mozilla.org/en-US/kb/configuration-options-accounts)

---

1. 1. 1. **V — Folder Subscriptions (IMAP)**

---

1. 1. 1. **Z — You're All Set! 🎉**

After saving these changes you should be able to send and receive emails. Other aspects of account configuration are optional and self-explanatory. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

You can always revisit settings via **☰ Menu → Account Settings** at any time.

> 💡 **Tip:** For the most up-to-date configuration details specific to your email provider, always check their official support documentation, as server settings can occasionally change.

Dear all, good evening With Thunderbirb for Android is not possible to read this massage. All other email clients has no problem. I attached picture to see the problem.

Since the most recent update ( or maybe a slightly earlier one,) I am unable to use macros on my Sidewinder X4 programmable keyboard. I can program a macro to a key but it does not work in Firefox. All other programs such as Word, Notepad etc. are fine. I am wondering if something in an update has broken it. It also works OK in Chrome

In the last two versions -- Firefox ESR - 115.34.1esr and 115.35.0esr -- the virtual keyboard (on-screen keyboard) is no longer visible. See attachments - login screen.png and Firefox version screenshot.png

1. Enable the search box to the right side of URL box in browser UI.
2. Open new tab (empty URL box).
3. Press TAB.
4. The search engine SELECTOR becomes highlighted, instead of the search INPUT.
5. Web application software developer is blocked from typing search query right away.
6. Must press ANOTHER TAB.
7. This breaks the workflow. It never used to do this, you could type immediately after tabbing ONCE.
8. Search is disabled in URL box to facilitate local domain resolution/error and NOT trigger fallback searching.

Please revert the behaviour to normal, and make the single TAB operation focus on the search INPUT.

some time ago I configured by thunderbird account to announce "You have mail" and it worked reliably until frontier moved email support to yahoo. Since then I get the "you have mail" announcement for a low percentage of new mail messages received. I contacted yahoo mail support and they responded that this is a problem with thunderbird and has nothing to do with yahoo. I suspect it's a matter of which process "sees" the new message first - thunderbird of yahoo mail. I've tried not having a yahoo mail window active, but that makes no difference. Most of the time now I get only a "gong" sound when a new mail message is received rather than "You have mail" voice notification.

149.0.2 (Build #2016153095), 9f0b9889e371a1c81cc665cfce6f53803006ad9b GV: 149.0.2-20260403140140 AS: 149.0 OS: Android 12

I've turned all Search SETTINGS to OFF. The Firefox Suggestion show up as soon as ANY characters are entered into the browser's search box.

I can setup the Calendar event, save it and see it in my Home Calendar along with the little bell icon in the top right hand corner which tells me the Calendar is aware of the notification request. I generally add a reminder for the Calendar event but just noticed that no actual reminders are being generated.

To install a Windows 10 update (I'm on extended support) I told it to update & shutdown. I fired it up this morning and Thunderbird is asking for credentials. It usually just runs & downloads emails. I enter my password, then a code from authenticator app. It shows the page below in an embedded browser window that has a checkbox and an "Agree" button. I check the box but the Agree button is still disabled. Dead end. I cannot connect & I'm stuck.
