Unless there has been a recent update, Sandboxie might still be incompatible with Firefox's multiprocess feature. More users are able to use multiprocess now that Legacy extensions are not blocking it. So more Sandboxie users may now encounter this issue.

Please see this recent thread (I didn't follow all the forum links to learn the details): To stop gah tab crashes in Firefox 57 (quantum) I had to disabled the multi-process function, but is there a fix?
