Safari uses too much memory on my system (rMBP 2013). By 'too much' I mean tens of gigabytes of memory. I experience constant memory pressure which leads to Safari freezes (it's freezing constantly even now while I'm typing this, and I have a single tab opened). It doesn't stop using memory until the entire SSD is full.
- The are no extensions installed (they are disabled in fact).
- I can't tell whether the issue is caused by any particular website; sometimes it happens when I don't have any seemingly "heavy" websites open.
How do I resolve this issue?

There are a number of things you can try...
Sometimes applications have memory leaks where the memory bloats over time, if you've been using Safari heavily, or using it for a long time without exiting and rebooting this could be an issue. Quitting Safari and reopening should fix this.
Check for extensions, and plugins that Safari uses to see if there are any malicious or unexpected plugins/try removing them temporarily to see if this fixes the issue.

Best to do a backup before tinkering in the Library folders!
