Any scrolling is determined by your client, not by Firebird itself.
The automatic scrolling may be a result of some master-detail
operation by whatever components you use. No-one can answer you
without knowing more about which components you use. Most likely this
is also a question suitable for a group for those components rather
than ib-support.

Yes, it is the same as an inner join, just written with an older
syntax (SQL-89). It is not as powerful as using join, and also poses
some extra challenges for you - e.g. with IBO you have to fill in
JoinLinks if using the above syntax, something which is redundant when
using join.
