The Bug of this Time!
For simplicity’s sake, let’s abbreviate, and wherever you see BotT, you know that’s Shmuel’s “Bug of this Time“.

I picked a bug from the FireFox BugZilla database (BugZilla is a (free) (opensource) (reliable) tool for tracking bugs).
The bug is Bug 233853 –, Ctrl+Enter goes to

This bug is very particular. Let’s first analyze the Bug Description:

Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040207 Firefox/0.8

I believe that’s good enough for a Build Identifier. It is the common practice on the DataBase to provide this info (check for yourself). And, from what I’ve seen, no much information on the system OS is given until asked by the programmers.
My belief on where this comes from: From one side, basic information on the environment can be very healthy for bug debugging. But on systems such as this, where the parameteres can change _so_ much from user to user, and people all over the world are running this application with different settings in different operating systems on different computers to do different things… Well, with so much differences, you better leave for the programmer to chose which information he wants :).

* Enter ‘’ in the URL field.
* Press CTRL-Enter
* Firefox changes the URL to ‘’.  Firefox prepends ‘www’ and
appends ‘com’ to whatever URL I type.
This does not happen if I provide a protocol or start the URL with ‘www.’

That is a very simple bug, with very simple reproduction steps.
It happens all the time to a lot of people, but Rick was the first to decide and report it.
Anyone can reproduce it from these instructions.

I pressed CTRL-Enter as I’m used to opening links in a background tab in
Mozilla.  I guess Firefox does not yet support opening background tabs.

Reproducible: Always
Steps to Reproduce:
1. Type a URL (sans protocol & ‘www’) in the URL field. (e.g.
2. Press CTRL-Enter
3. Notice Firefox prepends ‘www.’ and appends ‘.com’ to whatever URL you entered
without first attempting to connect to the URL provided.

Actual Results: 
Firefox prepends ‘www.’ and appends ‘.com’ to whatever URL you entered.

Expected Results: 
Firefox should just attempt to connect to the URL as typed.

This is an extension of the first-and-quick reproduction process.
It has additional information (like the background tab statement), a reproduction page that is not specific (in order not to have the discussion limited to and the expected results.

Pretty good!

Wait, if it is pretty good, and simple, and quick, why it is featured as the BotT?
Answer: Take a look at the bug thread — it has 46 posts, since 11/02/2004 until 16/10/2006! In almost three years, the bug was rolling back and forth between sides, until they get to some conclusion.
