Rather than juggling way too many tabs in Chrome, I sweep them all into OneTab and promptly forget about them—extensions and plugins are great. If I still had my own blog, I'd probably use them for all sorts of things, but third-party platform add-ons also represent a security concern.
It's important to double-check the provenance of anything you're considering adding, though I suspect few attackers will be quite as ambitious as the person who bought 30 WordPress plugins and then installed backdoors in all of them.
