User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3
Build Identifier: 3.0.2
Copying HTML from Firefox and pasting it into Thunderbird messages seems problematic. See "Steps to Reproduce" for more info.
Reproducible: Always
Steps to Reproduce:
1. Using Thunderbird 3.0.2 on OS X 10.5.8. I could not reproduce the problem with Thunderbird 2.0.0.23.
2. Click the "Write" button to compose a new message.
3. Click in the body area of the new message.
4. In your browser (I used Firefox 3.6; I could not reproduce the problem with Safari 4.0.4), go to the attached web page and copy the two lines of Perl code (I did not see the problem if I copied the text from this message in Entourage):
5. Press Command-V or Edit | Paste in the menu to paste the text from the clipboard (from the previous step) into the message body:
6. Hit Command-Z or Edit | Undo in the menu to attempt to undo the paste operation.
Expected behavior: Pasted text should disappear.
Behavior I'm seeing: Pasted text doesn't disappear.
7. Click on the style drop-down box and set the style to "Preformat", even if it is already checked.
8. Press Command-V or Edit | Paste in the menu to attempt to again paste the text from the clipboard.
Expected behavior: Text should be pasted.
Behavior I'm seeing: No text pasted. Thunderbird becomes unreponsive. OS X spinning beach ball ad infinitum until I manually kill Thunderbird. According to "top", Thunderbird uses nearly 100% of CPU while unresponsive.
Actual Results:
End result is Thunderbird uses around 100% CPU.
Here's the web page I used:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
</head>
<body>
<pre>
my $origin_server_client = $traffic_server_test->origin_server_client;
$origin_server_client->set_response_header('X-Custom-Header', 'Mango');
</pre>
</body>
</html>
