 The most common type of static extended filters are cosmetic filters, also known as "element hiding filters" in Adblock Plus.

 All static extended filters can be declared to apply to a specific _entity_. For example:

+A specific cosmetic filter of the following form...
+
+    *##.selector
+
+... will be unconditionally injected into all web pages, whereas a cosmetic filter of the form...
+
+    ##.selector
+
+... would be injected only when uBO's DOM surveyor finds at least one matching element in a web page.
+
+The new specific-generic form will also be disabled when a web page is subject to a `generichide` exception filter, since the filter is essentially a generic one -- the only difference from the usual generic form is that the filter is injected unconditionally instead of through the DOM surveyor.
+
+Specific-generic cosmetic filters will NOT be discarded when checking the "Ignore generic cosmetic filters" option in the "Filter lists" pane -- since the purpose of this option is primarily to disable the DOM surveyor.
+
+Specific-generic cosmetic filters should be used parcimoniously and only when using a normal specific filter is really impractical.
