Once you have logged in, you can customise various aspects of Bugzilla via the "Edit prefs" link in the page footer. The preferences are split into four tabs:
On this tab, you can change your basic account information, including your password, email address and real name. For security reasons, in order to change anything on this page you must type your current password into the "Password" field at the top of the page. If you attempt to change your email address, a confirmation email is sent to both the old and new addresses, with a link to use to confirm the change. This helps to prevent account hijacking.
This tab controls the amount of email Bugzilla sends you.
The first item on this page is marked "Users to watch". When you enter one or more comma-delineated user accounts (usually email addresses) into the text entry box, you will receive a copy of all the bugmail those users are sent (security settings permitting). This powerful functionality enables seamless transitions as developers change projects or users go on holiday.
The ability to watch other users may not be available in all Bugzilla installations. If you don't see this feature, and feel that you need it, speak to your administrator.
The "Field/recipient specific options" table allows you to determine how much mail Bugzilla sends you. The rows of the table define events that can happen to a bug -- things like attachments being added, new comments being made, the priority changing, etc. The columns in the table define your relationship with the bug:
Reporter - Where you are the person who initially reported the bug. Your name/account appears in the "Reporter:" field.
Assignee - Where you are the person who has been designated as the one responsible for the bug. Your name/account appears in the "Assigned To:" field of the bug.
QA Contact - You are one of the designated QA Contacts for the bug. Your account appears in the "QA Contact:" text-box of the bug.
CC - You are on the list CC List for the bug. Your account appears in the "CC:" text box of the bug.
Voter - You have placed one or more votes for the bug. Your account appears only if someone clicks on the "Show votes for this bug" link on the bug.
Some columns may not be visible for your installation, depending on your site's configuration.
To fine-tune your bugmail, decide the events for which you want to receive bugmail; then decide if you want to receive it all the time (enable the checkbox for every column), or only when you have a certain relationship with a bug (enable the checkbox only for those columns). For example: if you didn't want to receive mail when someone added themselves to the CC list, you could uncheck all the boxes in the "CC Field Changes" line. As another example, if you never wanted to receive email on bugs you reported unless the bug was resolved, you would un-check all boxes in the "Reporter" column except for the one on the "The bug is resolved or verified" row.
If you want to receive the maximum amount of email possible, check every box in every column. if you don't want to receive any email from Bugzilla at all, ensure that every box in this table is un-checked.
Your Bugzilla administrator can stop a user from receiving bugmail by adding the user's name to the data/nomail file. This is a drastic step best taken only for disabled accounts, as it overrides the user's individual mail preferences.
Bugzilla adds the "X-Bugzilla-Reason" header to all bugmail it sends, describing the recipient's relationship (AssignedTo, Reporter, QAContact, CC, or Voter) to the bug. This header can be used to do further client-side filtering.
By default, Bugzilla sends out email regardless of who made the change... even if you were the one responsible for generating the email in the first place. If you don't care to receive bugmail from your own changes, check the box marked "Only email me reports of changes made by other people".
On the Search page, you can store queries in Bugzilla, so if you regularly run a particular query it is just a drop-down menu away. Once you have a stored query, you can come here to request that it also be displayed in your page footer.
This is a purely informative page which outlines your current permissions on this installation of Bugzilla - what product groups you are in, and whether you can edit bugs or perform various administration functions.
