My first thought was that not long ago scientists were jumping up and down getting all exited because they found salt. Now there is tto much? Also, in order for there to have been life there must have been liquid water. We have no idea if it did let alone how much there might have been.
Just my thoughts....

I kinda know what you mean the impression i got when they first found water and salt deposits - was that mars was covered in shallow warm seas in its early history where lots of interesting life forms could of had a foothold.

But it seems that if they were any shallow seas they were a thick "brine" and possibly sterile as the salt content was very high.

However I always thought the earths seas were salty due to intense weathering - "weather" on mars seems kinda mild so how did its seas get so salty so early??

Mild? I would say yes of the Mars we see today but oceans affect weather and who knows what it was like back when mars had large amounts of surface water but being too salty kind makes since like Salt Lake, or the Dead Sea where slowly the ocean water is evaporated away and you end up with things like the Salt Flat etc.
