macOS Sierra Safari using all system memory

I have an early 2015 13" Retina MacBook pro, with 8GB of memory. I've been running Sierra for a while, but due to various self-inflicted issues, I decided on a clean install.

The reinstallation went well, but Safari is causing lots of problems. As soon as I open Safari, memory use goes up dramatically. Within a minute, Activity Monitor shows 9GB of memory used (nearly the same for compressed memory). Eventually, it just keeps going, and I have to force-quit. This happens after restarts, and I also disabled my one and only browser extension (1Password).

Again, no problems until after I wiped the drive and reinstalled MacOS 10.12.2 (16C68).

It would do well to note that the "clear the caches" approach is just a bandaid until Apple fixes the memory leak in Safari. Clearing the caches just prolongs the time between events.

Thank you! I have printed their instructions and will now attempt this myself. I've literally got nothing to lose at the moment.

Additionally (I had to reply - could not edit after 2 minutes...odd) - the "Safari corruption" link concerns "one" page on "one" site running slowly - not Safari as a whole. It's a different issue.
