I was just thinking the oceans get more and more salty all the time by the constant deposits by rivers and streams depositing their sodium chloride (and other minierals) in the ocean and then evaporating away --- leaving the salt behind in the oceans. So... Will there ever come a day that Earth's oceans become soo salty for example that fish, whales and other animals would no longer be able to live in them?

no, just the opposite is happening. the polar ice caps are melting, flooding the oceans with fresh water. salt water creatures cannot live in these environments. too little salt is a much bigger issue.

Well most likely not. The earth's bodies of water were actually saltier in the past. The dried up salt mines, great salt lakes, etc are remanents of ancient dried up bodies of water.
If it does become so salty that most modern aquatic life would die, the change will be gradual, allowing animals to evolve and adapt.

im no expert but i think they are doing just the opposite. because the ice is melting at the poles i would think that the salinity level of the ocean is decreasing rather than rising

i guess but with whatever happens its possible that the animals will adapt to their environment like they have been doing since the beginning

rivers are fresh water so they actually make the water less salty
