You can use both a filter and blocks, however this will
not work 100% reliable.

To remove script regions you can use a filter like:

FILTER: remove-scripts Remove script tags
s@<script[^>]*>.*</script>@@Ugis

Additionally you can block URLs ending with js:

{+block{JavaScript is disabled}}
/.*\.js

Some sites embed JavaScript in other tags using event attributes:

Preventing this requires additional filter rules.
