Hack 3. Find Stuff

Search both the Web and the browser environment
with Firefox.

This hack explains how to find the stuff you've
forgotten, left behind, or yet to discover. It starts with local
information in the browser and works its way out to searching the
furthest corners of the Web.

1.5.1. Search a Displayed Web Page

You can search the content of a displayed web page. To do so, Firefox
provides the Find toolbar. It appears at the bottom
of the browser window, above the status bar. Figure 1-5 shows most of the features.

Figure 1-5. The Find toolbar and associated menu items

This toolbar is
activated by the EditFind
or EditFind Again menu options or by the Ctrl-F (Command-F
on the Mac), Ctrl-G (Command-G on the Mac), or Shift-F3 hotkeys.
Here's a rundown of how it works:

The Find toolbar starts out disabled but gains the focus and the
caret in the toolbar text field when you click on it.

Type a string and Firefox automatically begins searching the current
page, starting from the page's focused form field,
or from the top of the page if no field is selected.

Firefox searches all frames but not all tabs. A security feature
terminates searching if the page is too big to search in five
seconds.

If nothing is found, the textbox goes red. "Phrase
not found" appears, and a sound is issued.

If something is found, you can navigate between items with toolbar
arrows or Ctrl-G (Command-G on Mac) and
Shift-F3.

You can highlight found items with the Highlight toggle button.

Press Ctrl-F (Command-F on Mac) again and the current search string
is selected for replacement. Dismiss the toolbar by clicking the
small cross icon located at its right end.

The Find toolbar contains two searches in one. The default search is
the one just described, called Find As You
Type. It can also be activated with the forward
slash (/) key, or if there's
nothing focused on the current page and you just start typing. The
other kind of search is called Find Links As You
Type. It can be activated with the
single quote key ('). This alternate search scans
only hyperlink text on the page. Use it to find specific links on big
pages crowded with links.

1.5.2. Search Web Page Source

You can also search the source code of a
web page, something that was never possible in old Netscape browsers.
View the page's source by choosing
ViewPage Source or with the Ctrl-U (Command-U) hotkey. A
new window appears. That window has an Edit menu with the options
Find (Ctrl-F or Command-F), Find Again (Ctrl-G or Command-G) and Go
to Line (Ctrl-L or Command-L). Choose any of these and a small dialog
box appears to control your search. Figure 1-6
shows most of the available features.

This searching system doesn't use a Find toolbar,
but it's similar. It supports full content searching
only and doesn't support link searching. It does,
however, support case-sensitive searches.

1.5.3. Search Your History

There are several ways to search
your
surfing
history.
Figure 1-7 maps out these features.

Figure 1-7. History searching features

The most accurate search uses the Back and Forward buttons. Press the
small, black down-arrow grippies that sit to the right of these
icons. A drop-down list of the web trail
for the
current window appears. If you ever surfed up a blind alley, then
reversed, and went forward in a different direction, the set of blind
alley pages is lost from the web trail. Full URLs, form data, and
scrolled position are all otherwise preserved.

For another way to search, try the
Go menu. It shows the most recently
viewed URLs across all windows' session
history. Only remote web pages are shown. Form
posts and page scroll positions aren't preserved. As
you view more pages, older items are pushed off this menu. To
increase the size of the session history, modify this preference
[Hack #23] :

browser.session_history.max_entries /* 50 is default */

The History sidebar, displayed with
ViewSidebarHistory (Ctrl-H or Command-H),
provides the broadest search. It records your global
history (all the web pages examined in the last
nine days). It searches the titles of those
pages onlyno title content, no match. Delete the search string
to see the day-wise hierarchy of pages again. Hack these preferences
to change the defaults:

browser.history_expire_days /* 9 is the default */
browser.history.grouping    /* "none", "day" or "site" */

Finally, the Location bar can be used to search recently visited web
sites in your global history. Type any string into the location bar
and suggested domain name matches automatically
appear in a drop-down list below the text box. This is called
auto-complete. You can't search
for path-specific bits of a URL until you've got the
whole domain name (e.g., http://www.yahoo.com) right.

1.5.4. Search Your Bookmarks

Are you overflowing with
bookmarks
and can't remember any of them? Open the Bookmark
Manager using BookmarksManage Bookmarks... and type
something into the search window. This search examines the full URLs
of all bookmarks and their descriptions. The descriptions usually
match web page titles, unless you changed the titles when storing the
bookmarks. You can also sort the Bookmark Manager's view
of your bookmarks from the View menu, which might be helpful.
It's almost a depth-first tree
sort, though, which is a
sophisticated sort. It takes a bit of getting used to. Try it.

1.5.5. Search for Lost Logins

Typed your username and password into a web site and then forgot what
they were? Firefox can help. Choose ToolsOptions to bring
up the Options dialog box. On Unix/Linux, it's under
EditPreferences. On Macintosh it's under
Options in the Application menu. Click the Privacy icon. Note
the Saved Form Information and Saved Passwords items. Click each
one's
expando (the small plus icon) in turn. Turn on the
various options by clicking their corresponding checkboxes, as shown
in Figure 1-8.

Figure 1-8. Options preferences for form and password tracking

Visit a web page with a form containing at least one text box, fill
it in, and submit. Google's home page (http://www.google.com) is a good choice. Open
a new Firefox window. Visit the page again. Left-click on the textbox
twice. A drop-down menu appears, showing you the value you just
typed. Pick the one you
want.

Alternatively, visit a web page requiring a login. I log in at
http://bugzilla.mozilla.org a lot
(follow the login link). Use Firefox's form
completion to enter your username, and Password Manager automatically
adds the password. Just click the Login button and
you're in.

Later on, you can review what you've saved. Back in
the Options dialog box, under PrivacySaved Passwords, click
the View Saved Passwords button. In the resulting dialog box, click
Show Passwords and Yes. Your passwords appear in plain text as an
additional table column. Found them!

1.5.6. Search the Web

The Navigation toolbar includes a Search
field on the extreme right. It uses the Google search engine by
default. Type a keyword into the field and press Enter.
Google replaces the current
page with its search results. Alternatively, click on the small
Google icon to see the other search engines installed by default; you
can use any of them as well. Empty the Search field again and type a
common letter, such as a. The Search box drops
down a list of keywords starting with a that
you've typed before.

1.5.7. Search for Firefox Preferences

Firefox has lots of preferences.
Type
in the URL about:config to see many (but not all)
of them. There are too many to understand all at once. Type anything
into the textbox labeled Filter: to restrict the
list to the ones you care about (try typing go).
The set of preferences is marginally different between Linux and
Windows, but 99 percent of Firefox preferences apply to all
platforms.
