RLBox
I would like to use this issue as a way to investigate what's the current status of RLBox (also known as wasm-sandboxing) in the various LW releases, and to offer help to get this working.
I know we had issues with this, as mozilla doesn't provide an easy way to include RLBox, or to verify if this is enabled (although this might change at some point). best way to make sure is to check you didn't exclude it in the build options with ac_add_option --without-wasm-sandboxed-libraries, then you can check the build logs to make sure it was included.
if you need help for a fix I did it this way and then added ac_add_options --with-wasi-sysroot=$HOME/.mozbuild/wrlb/wasi-sysroot, but feel free to ask here. as discussed, we want this to be part of the builds. maintainers of unofficial builds that want to include this security feature and need help are also welcomed in this issue, same goes for people building from source.
if it's part of your build check the box below and maybe post a comment to confirm:

appimage -
debian ( deb.librewolf.net) -
fedora ( rpm.librewolf.net) -
