+ <h4>What is Redirector?</h4>
+
+ <p>Redirector is an extension for Firefox that allows you to automatically redirect from
+ one webpage to another. For example, every time you visit http://abc.com you will automatically
+ load http://def.com instead. This can be useful for instance to always redirect articles to printer friendly
+ versions, redirect http:// to https:// for sites that support both, bypass advertising pages that appear before
+ being able to view certain pages and more.</p>
+
+ <a name="basicusage"></a>
+ <h4>Basic usage</h4>
+ <p>To add a new redirect you can go to the <em>Tools</em> menuitem and select <em>Redirector</em>. That will
+ open the <em>Redirector settings</em> window which shows all your redirects. The window can also be opened
+ by right clicking on the <strong>R</strong> icon in your statusbar and selecting <em>Manage redirects</em>.
+ There you can press the <em>Add...</em> button and then you can enter the details for the new redirect. A redirect
+ consists of a few things:
+ <ul>
+ <li><a name="exampleurl"></a><strong>Example url:</strong> This is an example of an url you want to redirect. It is not really used for anything,
+ it's just there to show what types of urls you're targetting. You can leave this out, but then you can't use the <em>Test pattern</em> button.</li>
+
+ <li><a name="includepattern"></a><strong>Include pattern:</strong> This is pattern for the urls you want to redirect. In the simplest case, where you just want
+ to redirect one specific url to another then this will just be the exact url you want to redirect. For instance, if you just want http://aaa.com to
+ redirect to http://bbb.com then <em>Include pattern</em> will just be http://aaa.com. For more complex patterns that match many
+ urls you can use either <a href="#wildcards">wildcards</a> or <a href="#regularexpressions">regular expressions</a>.</li>
+
+ <li><a name="excludepattern"></a><strong>Exclude pattern:</strong> Urls that match this pattern will never be redirected. This is not necessary to
+ fill out, but can be useful when you want to redirect all urls that contain some text except if they contain some other text.
+ Redirects like that can often be done with a complex regular expression, but using an exclude pattern makes it much simpler. The exclude
+ patterns can use wildcard characters or regular expressions like the include patterns.</li>
+
+ <li><a name="redirectto"></a><strong>Redirect to:</strong> This is the url that you will be redirected to when you open any page where the url matches the
+ include pattern. You can use the special signs $1, $2, $3 etc. in the url, they will be replaced by the results of captures with regular
+ expressions or stars with wildcards. For instance, if you have the include pattern <em>http://google.com/*</em>, redirect to <em>http://froogle.com/$1</em>
+ and you open the page http://google.com/foobar, then you will be redireced to http://froogle.com/foobar, since 'foobar' was what the star replaced. $1 is for the
+ first star in the pattern, $2 for the second and so on. For regular expression $1 is for the first parantheses, $2 for the second etc. The redirect url
+ can also be specified as a <a href="#xpathredirects">XPath expression</a>.</li>
+
+ <li><a name="patterntype"></a><strong>Pattern type:</strong> This specifies how Redirector should interpret the patterns, either as
+ <a href="#wildcards">wildcards</a> or <a href="#regularexpressions#">regular expressions</a>.</li>
+
+ <li><a name="onlyiflinkexists"></a><strong>Only if link exists:</strong> If this is checked then the redirect will only happen if there is a link
+ to the target page on the page that matches the include pattern. For instance, if you have a redirect from http://foo.com to
+ http://bar.com and check <em>Only if link exists</em> then http://foo.com has to have a hyperlink to http://bar.com, otherwise
+ nothing will happen.
+ </li>
+ </ul>
+ </p>
+
+ <a name="wildcards"></a>
+ <h4>Wildcards</h4>
+
+ <p>Wildcards are the simplest way to specify include and exclude patterns. When you create a wildcard pattern there
+ is just one special character, the asterisk *. An asterisk in your pattern will match zero or more characters and you can
+ have more than one star in your pattern. Some examples:
+ <ul>
+ <li><em>http://example.com/*</em> matches http://example.com/, http://example.com/foo, http://example.com/bar and all other urls that start with http://example.com/.</li>
+ <li><em>http://*.example.com</em> matches all subdomains of example.com, like http://www.example.com, http://mail.example.com.</li>
+ <li><em>http*://example.com</em> matches both http://example.com and https://example.com.</li>
+ <li><em>http://example.com/index.asp*</em> matches http://example.com/index.asp, http://example.com/index.asp?a=b&c=d.</li>
+ </ul>
+ $1, $2, $3 in the redirect urls will match the text that the stars matched. Examples:
+ <ul>
+ <li><em>http://example.com/*</em> matches http://example.com/foobar, $1 is foobar.</li>
+ <li><em>http://*.example.com/*</em> matches http://www.example.com/foobar, $1 is www, $2 is foobar.</li>
+ </ul>
+ </p>
+
+ <a name="regularexpressions"></a>
+ <h4>Regular expressions</h4>
+
+ <p>Regular expressions allow for more complicated patterns but they are a lot harder to learn than wildcards. I'm not gonna
+ create a regex tutorial here but normal javascript regex syntax works, look at <a href="http://regular-expressions.info" target="_blank">http://regular-expressions.info</a> for
+ an introduction to regular expressions. $1,$2 etc. can be used in the redirect url and will be replaced with contents of captures in
+ the regular expressions. Captures are specified with parantheses. Example: http://example.com/index.asp\?id=(\d+) will match the url
+ http://example.com/index.asp?id=12345 and $1 will be replaced by 12345. (A common mistake in regex patterns is to forget to escape
+ the ? sign in the querystring of the url. ? is a special character in regular expressions so if you want to match an url with a querystring
+ you should escape it as \?).</p>
+
+ <a name="xpathredirects"></a>
+ <h4>XPath redirects</h4>
+ <p>The redirect url can be specified as an xpath expression by starting it with xpath: and then you will be redirected to the url
+ that the xpath expression matches. Example: Redirect url is xpath:/div/span/a/@href, then you will be redirected to the href value
+ of the first link that's inside a div in the original page.</p>
