I've documented a couple "set and forget" ways of applying the "--enable-remote-extensions" workaround here. It works for me on Debian sid so I think it'll work on Siduction as well.
I'd never needed to add the "--enable-remote-extensions" until the 55.0.2883.75-4 version (with the fix), and I don't need it after that. (Currently on version 55.0.2883.75-6.)
EDIT: I was wrong here. My extensions were not present without the "--enable-remote-extensions" option.
