In thunderbird, Note that when viewing it in thunderbird, it has both a "body" and a "footer". Now forward it inline. Observe how the "body" disappears from the forward. Yes, the HTML in the message is bad, but (a) that's how I received it (although obviously I've removed all the non-markup text for illustrative purposes), so somebody's generating this bad HTML and thunderbird needs to cope with it, and (b) if thunderbird can handle displaying it properly, then it should be able to handle forwarding it properly.

Confirmed. Tag structure of original message that causes this: HTML BODY -- CONTENT -- /BODY /HTML HTML BODY -- FOOTER -- /BODY /HTML Seems that MS Outlook creates this bad code. Note: Reply corrects HTML content by removing extra BODY and HTML tags, thus allowing the entire message to be replied to. Forward does not do this, dropping all but the last BODY block.

Still broken in Thunderbird 3.1.1.
Still broken in Thunderbird 13.0, as seen in bug 777701. (1) This bug Bug 777701 <html> <html> <head>...</head> <head>...</head> <body>...BODY part...</body> <body>...BODY part... </html> 2nd HTML is inserted 2nd HTML is appended <html> <html> <head>...</head> <head>...</head> <body>...FOOTER part...</body <body>...FOOTER part...</body> </html>> </html> </body> </html> (2) In both cases, even when 2nd <html> was changed to HTML comment, problem was still observed. And, "BBB --->" was shown before FOOTER part by Forward inline. <1-- AAA <html> BBB --> => Bad handling of multiple <html> tags in text conversion by Forward inline. HTML comment process is broken by the bad <html> handling. (4) If 2nd <html> tag is removed(replaced by <htmlXXX>), problem disappears. <1-- AAA <htmlXXX> BBB --> <htmlXXX> (4) Abve is observed with any of View/Message Body As mode. Original HTML, Simple HTML, Plain Text.

Additional check results. (6) If attribute value is added to second or later <html> tags, all body text string including string in first <html xmlns..> are shown by Forward inline and problem disappears. <html xmlns...> <head>...</head><body>...first-body-text....</body></html> <html id="root_02"><head>...</head><body>...second-body-text...</body></html> <html id="root_03"><head>...</head><body>...third-body-text....</body></html> <html id="root_04"><head>...</head><body>...fourth-body-text...</body></html> If id attribute is removed from 2-nd to 4-th html tag, problem is reproduced and first-body-text is not shown by Forward inline. (7) If attribute value of first html tag is removed, problem is not observed, even when no attribute in 2-nd to 4-th html tag. <html><head>...</head><body>...first-body-text....</body></html> <html><head>...</head><body>...second-body-text...</body></html> <html><head>...</head><body>...third-body-text....</body></html> <html><head>...</head><body>...fourth-body-text...</body></html> Simlar "affect by atribute of <html> tag in Forward inline" is seen in problem of bug 313401 too, although that bug is problem only with "Simple HTML mode" && "multipart/related HTML mail" && "Single html tag only".

4 mails are simplest text/html mail. ----------- this bug ----------- ---------- bug 670884 ---------- Test mail #11 #12 #21 #22 <html id=abc> <html id=abc> no <html> tag no <html> tag <p>body text<p> <p>body text<p> <p>body text<p> <p>body text<p> </html> </html> <!-- <!-- <!-- <!-- AAA AAA AAA AAA <html> <html id=abc> <html> <html id=abc> BBB BBB BBB BBB --> --> --> --> Quoted message body text by Forward inline : BBB --> body text BBB --> body text Forward inline of Tb ignores any body element before the string of <html> in HTML comment, and interprets "string after <html> till -->" as body text. Bug 313401 is perhaps special case of above problem. Even when no excess string of <html> exists after valid/first html tag with attribute value(<html xmlns...> or <html id=abc>), if mail is multipart/related HTML mail and if Simple HTML mode, similar situation to "excess string of <html>" is internally generated by sanitizing for Simple HTML mode.
Setting dependency of Bug 313401, for ease of tracking and problem analysis.
