I can reproduce this with same Firefox version. On latest Chrome, it is working well.

Seems like a bug with firefox - I get this this error...

s should be a valid flag.

So that's why the solution passed our tests, but is failing in firefox. This will be a problem anywhere else we used the s flag. Fortunately, it's not something that is used in many other places, if any.

Open bug report on Bugzilla about the s flag - https://bugzilla.mozilla.org/show_bug.cgi?id=1361856

Doesn't look like it will be implemented anytime soon.
