Unable to add HTML filtration rule

[Roman753]

I am trying to add HTML filtration rule ( $$script[type="text/javascript"][tag-content="bestpizzaeverad.com"] from the example on http://adguard.com/en/filterrules.html ) to my filter list (User filter) but the rule disappears.

How to add HTML filtration rule?

I might be wrong, but I don't believe those type of rules are supported by the browser extensions nor would they'd work anyways.

These type of rules is not supported by browser extensions.
The problem is that extensions cannot change HTML content before page has been loaded.
