        "content": "Could you just double-check some details so I give the best advice for *your* issue? When you say the \u201cHeader information is being inserted and people are getting it included in the post,\u201d do you mean one of these situations:\n\n- You\u2019re sending a **reply** or **reply-all**, and the original message\u2019s header (From, To, Cc, Date, etc.) is being quoted in the body and visible to everyone.  \n- You\u2019re **forwarding** a message, so headers are included (which is normal).  \n- Or Thunderbird is embedding some private header info *automatically* even on new messages (not reply or forward)?  \n\nIf it's replying/forwarding: Thunderbird **forwards** full header blocks by default, but **replies** only include basic info by design (e.g. \u201cOn date, sender wrote:\u201d). Thunderbird doesn\u2019t officially provide a setting for replies to act like forwards in terms of included headers. ([support.mozilla.org](https://support.mozilla.org/bm/questions/1267081?utm_source=openai))\n\nIf that matches you (i.e. replies are getting excessive header text in the body), here are some things you **can** try to reduce or remove headers:\n\n---\n\n## \u2705 Things to Try\n\n### 1. Always use **Reply** instead of Forward\n- Forwarding includes more header details (all recipients, etc.), whereas reply only shows minimal header lines automatically. When replying to a message, it should *not* include the full \u201cTo:, Cc:, etc.\u201d by default. If you forward, it will.  \n\n### 2. Edit the quoted section manually\n- You can usually highlight and delete that header text in the composition window before sending. It may require selecting lines and using delete/backspace. Even though this might be more work if you reply often.\n\n### 3. Use Thunderbird add-ons that control header quoting/format\n- There are add-ons like **ReplyWithHeader** which can change how reply quoting works. However, from what people report, it *adds* headers rather than removes them; useful if you want more control, but it may not help if your problem is too much. ([support.mozilla.org](https://support.mozilla.org/en-US/questions/1323778?utm_source=openai))\n\n---\n\n## \u2699\ufe0f More Permanent/Technical Solutions\n\nThese are more complex but might work well, especially since being totally blind suggests you want a reliable, consistent setup.\n\n### Use \u201cPlain Text\u201d instead of HTML format\n- Sometimes HTML quoting shows header blocks in a table or with styling; plain text replies show simpler lines. You can force plain-text compositions: go to **Account Settings \u2192 Composition & Addressing** and *disable* HTML, so all quoting is simpler.  \n\n### Check/Modify quote header template via SmartTemplate4\n- If you use extensions like **SmartTemplate4**, you may alter the template used when replying, to omit \u201cTo:\u201d or \u201cCc:\u201d lines. ([systutorials.com](https://www.systutorials.com/outlook-style-email-reply-header-thunderbird/?utm_source=openai))\n\n### Using Thunderbird\u2019s advanced settings (\u201cabout:config\u201d / Config Editor)\n- While there isn\u2019t a built-in preference to stop replies from including header info entirely, there *is* a setting you can use to control which headers are visible in the **message display pane** (not necessarily what gets quoted).  \n- For example: `mailnews.headers.extraExpandedHeaders` lets you define which additional headers show (if any) in the display pane of messages. That affects *viewing*, not quoting. ([support.mozilla.org](https://support.mozilla.org/si/questions/1459405?utm_source=openai))\n\n### Using userChrome.css to hide header display\n- If the issue is *viewers* see a header above the message, but you don\u2019t want that visual clutter (or maybe screen reader announces it), you can hide certain parts using a `userChrome.css` file. For example:\n  ```css\n  #msgHeaderView { display: none !important; }\n  ```\n  or\n  ```css\n  .header-to-row { display: none !important; }\n  .header-from-row { display: none !important; }\n  ```\n  This affects how Thunderbird shows or hides the header section in message viewing, not what gets included inside the body when sending. ([superuser.com](https://superuser.com/questions/1874629/how-to-hide-thunderbirds-message-header-between-the-message-list-and-message?utm_source=openai))\n\n---\n\nIf you tell me which version of Thunderbird you\u2019re using, and on which OS (Windows, macOS, Linux), I can walk you through steps specific to you\u2014especially for setting plain text, adjusting your quote header template, or using an add-on to avoid exposing headers when you reply. Would you like me to send that custom walkthrough?"

        "content": "Thanks for clarifying. By \u201cheader=0,\u201d it sounds like you're seeing the internal headers or extra metadata included when you forward or reply \u2014 things like:\n\n- \u201cSubject: \u2026\u201d,  \n- \u201cDate: \u2026\u201d,  \n- \u201cFrom: \u2026\u201d,  \n- \"To: \u2026\"  \n\n... all appearing in brackets or in the quoted/inserted text.\n\nHere\u2019s how to **stop or reduce** that information in Thunderbird, especially since you're blind and want the simplest, most consistent fix.\n\n---\n\n## What\u2019s actually happening\n\n- When you **forward** a message, Thunderbird by default includes a block of full header lines (From, To, Date, Subject, etc.) before the original message. ([support.mozilla.org](https://support.mozilla.org/bm/questions/1267081?utm_source=openai))  \n- When you **reply** (or reply all), Thunderbird usually adds only a short, minimal line like *\u201cOn [Date], [Sender] wrote:\u201d*, not the full headers. ([support.mozilla.org](https://support.mozilla.org/bm/questions/1267081?utm_source=openai))  \n- If you\u2019re seeing a lot of header info even in replies, or if the minimal information is still too much, there are settings and tweaks you can use. Also, if \u201cHeaders \u2192 All\u201d is enabled in View, that can show a lot more in some display cases. ([wiki.cacert.org](https://wiki.cacert.org/ThunderBirdAdvancedConfig?utm_source=openai))  \n\n---\n\n## How to reduce or remove these header lines\n\nThese are ways to get rid of those header blocks, especially when forwarding or quoting. Since you\u2019re blind, I\u2019ll aim for methods that work without needing precise mouse actions.\n\n1. **Delete the text manually before sending**  \n   When you see the header block in the compose window, you can use keyboard navigation (e.g. using arrow keys) to reach it and then backspace or select and delete. It\u2019s a manual method, but reliable.\n\n2. **Use \u201cEdit As New Message\u201d to resend without header block**  \n   If you want to forward something but don\u2019t want any of the header lines:\n\n   - Select the message.\n   - Use *Message \u2192 Edit As New Message*. This opens the message as if you are composing a brand-new one, with just the body content. You can then delete the header text if it's still there.\n\n3. **Change advanced preferences for reply header behavior**\n\n   Thunderbird has hidden settings in `about:config` that you can change:\n\n   - `mailnews.reply_header_type` controls how much header information appears in replies:\n     - `0` = No reply-text (so nothing like \u201cOn date \u2026 wrote:\u201d appears at all).  \n     - `1` = Just \u201c[Author] wrote:\u201d.  \n     - `2` = \u201cOn [date] [author] wrote:\u201d.  \n     - `3` = User-defined line. ([wiki.cacert.org](https://wiki.cacert.org/ThunderBirdAdvancedConfig?utm_source=openai))  \n\n   - Other related prefs:\n     - `mailnews.reply_header_authorwrote`\n     - `mailnews.reply_header_ondate`\n     - `mailnews.reply_header_separator`\n     - `mailnews.reply_header_colon`  \n     By adjusting those, you can remove entirely or simplify the reply header line. ([wiki.cacert.org](https://wiki.cacert.org/ThunderBirdAdvancedConfig?utm_source=openai))  \n\n4. **Use \u201cView \u2192 Headers \u2192 Normal\u201d**\n\n   When viewing message content, if \u201cHeaders \u2192 All\u201d is enabled, that might show extra internal header lines. Setting it to \u201cNormal\u201d reduces the visible header information. ([wiki.cacert.org](https://wiki.cacert.org/ThunderBirdAdvancedConfig?utm_source=openai))  \n\n---\n\nIf you tell me **which version** of Thunderbird you're using (e.g. Thunderbird 115, 115.4, something newer or older) *and* your operating system (Windows, macOS, Linux), I can walk you through *exact keystrokes* or steps to set `mailnews.reply_header_type` to 0 or otherwise strip down the headers. Do you want me to send those instructions now?"
