# Compatibility with other extensions

While it is not known to be a common problem, Haketilo may interfere with or experience interference from other extensions- especially other content blockers. Extensions  where information on this is available are documented here.

## LibreJS

Haketilo can be used alongside LibreJS on pages where payloads will not be injected if its default policy is set to allow pages' own scripts; otherwise LibreJS' filtering will be overridden. All configuration of script-blocking in such a setup, including whitelisting and blacklisting, should be done through LibreJS only.

Pages with payloads will have all scripts blocked anyway, as is the expected behavior for Haketilo.

## NoScript

NoScript is *expected* to be mostly safe for use with Haketilo; however, on Mozilla Firefox and its derivatives, enabling NoScript's script blocking capabilities will prevent payload injection. Further testing is required to confirm no other issues exist.

## LibreJS/USPS compatibility and other site fixes shipped with IceCat

These will conflict if a corresponding payload is installed in Haketilo. We advise disabling them; work is currently ongoing to port these to Haketilo.
