Answer 2

For me, it eats no more than 1 GB (without extensions and other modifications) on the 64-bit version.
That's why.

Answer 3

Because it makes no sense not to eat, since there is something.
The system will not have enough memory - free up.
On my system with 3 gigs. Chrome eats 10-60 meters per tab.

Answer 4

It's written that way. You can't do anything about it. There are several possible solutions:
- Find another browser
- Remove some of the extensions.
You can only demolish it completely (with cache, settings, history, extensions, etc.).
