Thunderbird Bug Fix Lab
Contents
Overview
This lab is designed to give you first-hand experience working through a real bug, from confirming to fixing to submitting a patch. You will also get experience building and working with Thunderbird, which shares much of the same code with Firefox.
Introduction
A friend has told you about something they don't like in Mozilla Thunderbird. "I got an email today, and it made a hyperlink out of some text that shouldn't have been underlined."
Here is the text of the email:
Does Wednesday aft. work for you? I'll tentatively schedule for 3:30 on Wednesday. We'll come to S@Y...where should we meet?
which is being displayed as follows in Thunderbird:
Does Wednesday aft. work for you? I'll tentatively schedule 3:30 on Wednesday. We'll come to S@Y...where should we meet?
You rightly identify this as a bug to your friend, and offer to try and fix it.
