How RLBox works is complicated, but it breaks down by archetypal compiling a process into WebAssembly, and past the converted process is past re-converted into autochthonal code.

To bash this, Firefox uses RLBox to spot 2 cardinal restrictions connected people code:

  • It isn't allowed to leap to unexpected parts of the program.
  • It can't entree representation extracurricular of a circumstantial region.

These 2 restrictions marque it harmless for Firefox to stock an code abstraction betwixt trusted and untrusted codification truthful they tin tally successful the aforesaid process.

RLBox is simply a large measurement guardant for Firefox information due to the fact that it protects users from accidental defects and supply-chain attacks. As an added benefit, RLBox reduces the request for the developers to scramble and hole thing erstwhile an contented is disclosed upstream.
