Why a protected page can break

A site can depend on a script that also tracks people. Blocking that script may remove a video, comment panel or sign-in widget.

What SmartBlock can do

Firefox-derived compatibility logic may substitute a harmless local component for certain blocked scripts. This can help a page function while retaining protection, but it is not available for every site or script.

If the page still fails

Check the protection icon, site permissions and extensions. Try a narrow site exception only as a temporary diagnostic step, then restore protection when possible.

Use exceptions briefly, then remove them.
