Bartab extension - how much of this function is implemented in FF6?

Question

I abso LOVED Bartab so much I'm thinking about DOWN-GRADING Firefox to v.3 to use it. I'm at v.5 now.
Bartab does not "open" restored tabs until clicked on. Tabs go to sleep automatically after X minutes, or can be put to sleep manually.
Are these features in FF6? Can they be implemented in About:config? FF5 implements this partially, by keeping tabs "inactive" or "unloaded" on restore, until I click on them.

Are you able to use the command line version of ttSize instead? This splits out how much space is being used by indexes (in the Temp section of the TT memory segment), which I think is being combined into one, whole figure in the procedure version of ttSize you're using. For example:
ttSize -tbl ia my_ttdb
Rows = 4
Total in-line row bytes = 17524
Total = 17524
Command> create index i1 on ia(a);
ttSize -tbl ia my_ttdb;
Rows = 4
Total in-line row bytes = 17524
Indexes:
Range index JSPALMER.I1 adds 5618 bytes
  Total index bytes = 5618
Total = 23142
Command> call ttsize ('ia',,);
< 23142.0000000000 >
1 row found.
In 11.2.2 we added the procedure ttComputeTabSizes which populates system tables with detailed table size data, and was designed to be an alternative to ttSize. Unfortunately it still doesn't calculate index usage though, and it isn't in 11.2.1.
