After a few weeks of testing NGLayout (also known as Gecko) builds and discussing them on newsgroups, I filed my first Mozilla bug fifteen years ago.

Back then, the bugmail looked like this:

+ Bug#: 845
+ Product: NGLayout
+ Version: other
+ Platform: PC
+ OS/Version: Windows 95
+ Status: NEW
+ Resolution:
+ Severity: normal
+ Priority: P2
+ Component: Parser
+ Area:
+ AssignedTo: rickg@netscape.com

+ Cc: ARRAY(0x2504b0)
+ Summary: CSS Parser ignoring first declaration in STYLE element surrounded by comments
+
+ When CSS in a STYLE element is enclosed in SGML comments (as described at the
+ end of section 1.1 in http://www.w3.org/TR/REC-CSS1#containment-in-html ), the
+ first declaration is ignored.  See http://www.w3.org/TR/REC-CSS1#containment-in-
+ html , where the P elements (about half of the page) should be red.
+
+ (I didn't test other pages to see if this happens all the time.)
+
+ (I also didn't know whether to file this under Parser or Style System.)&#137;

This was before context diffs (as opposed to unified diffs) had gone completely out of style. This becomes clearer when you see the following change I got for this bug:

Mozilla and the Web have come a long way in the last fifteen years. And so has Bugzilla.
