I noticed that no new versions of Firefox Portable Edition 4.0 Beta have been released after Beta3 on 13 august, while in the mean time Beta4, 5 and 6 have been released from Mozilla.
Is there a particular reason for that or is it just a matter of time or a coincidence?
Obviously I'm not complaining at all; just curious.
In the meantime Firefox 4 beta 6 has been published:

the last post gives the link to pa.c FF Beta 6, this is where Mozilla is still at.
if you want anything newer, follow my guide here:
