Nit: "only" doesn't make sense here any more.

Done.

 
   <p>{{s86 The <a href="elemhidehelper">Element Hiding Helper extension</a> helps selecting the correct element and writing the corresponding rule without having to view the source code of the page. Basic HTML knowledge is useful nevertheless.}}</p>
 
   <p>{{s87 <em>Note</em>: Element hiding works very differently from normal filters. This has the implication that no wildcards are supported in element hiding rules.}}</p>
 
   <h3 id="elemhide_domains">{{s88 Limiting rules to certain domains}}</h3>
 
-  <p>{{s89 Usually you want to hide a specific ad on one specific site, you don't want your rule to be applied on other sites. For example the rule <code><fix>##*.sponsor</fix></code> might hide valid code on some sites. But if you write it as <code><fix>example.com##*.sponsor</fix></code> it will be applied on <code><fix>http://example.com/</fix></code> and <code><fix>http://something.example.com/</fix></code> but not on <code><fix>http://example.org/</fix></code>. You can also specify multiple domains — simply separate them with commas: <code><fix>domain1.example,domain2.example,domain3.example##*.sponsor</fix></code>.}}</p>

   <p>{{s91 <em>Note</em>: Due to the way how element hiding is implemented, you really can only limit it to full domain names. You cannot use any other part of the address and you cannot use <code><fix>domain</fix></code> as a replacement for <code><fix>domain.example,domain.test</fix></code>.}}</p>
 
   <p>{{s92 <em>Note</em>: Element hiding rules with domain limitation can be used to hide browser's user interface elements as well. For example the filter rule <code><fix>browser##menuitem#javascriptConsole</fix></code> will hide the JavaScript Console entry in Firefox's Tools menu.}}</p>
 
   <h3 id="elemhide_attributes">{{s93 Attribute selectors}}</h3>
 
   <p>{{s94 Some advertisers don't make it easy for you — their text advertisements have neither an id nor a class attribute. You can use other attributes to hide those, for example <code><fix>##table[width="80%"]</fix></code> will hide tables with width attribute set to 80%. If you don't want to specify the full value of the attribute, <code><fix>##div[title*="adv"]</fix></code> will hide all div elements with title attribute containing the string "adv". You can also check the beginning and the end of an attribute, for example <code><fix>##div[title^="adv"][title$="ert"]</fix></code> will hide div elements with title starting with "adv" and ending with "ert". As you see, you can also use multiple conditions — <code><fix>table[width="80%"][bgcolor="white"]</fix></code> will match tables with width attribute set to 80% and bgcolor attribute set to white.}}</p>

-  <p>{{generic-specific-explanation-p2 We classify a filter to be <strong>specific</strong> if it matches one or more domains or matches a sitekey.
