TBH I think the comments you make, TB, on Chrome are a little unfair. Security updates happen twice a month instead of monthly for most other browsers so there is less time between vulnerabilities and fixes. IE6, launched 14 odd years ago, still had a dozen or so vulnerabilities last year (and yes people still use it for backward compatibility issues) which doesn't bode well for any more recent versions of IE. Chrome is also the only browser to sandbox flash video (hence the heavy resource requirement) and flash is a major vulnerability to any browser. To suggest that IE or any other browser does not have weaknesses in it's security would be a misnomer. Both Chrome and IE have about the same number of reported vulnerabilities each year. Opera is a pile of poo as is Firefox. I only have the latter installed in order to perform tests for my current client who is getting ditched end of this week 
IE's biggest advantages, security wise, are the fact it updates with Windows, and that MS were an early target, and have been through the rough times. Its weakness is that a) Its users are stupid (run as Admin, knock off UAC coz the bloke down the pub said so), b) it supports plugins quite openly (which coupled with a) makes for a perfect storm).
The reason that Flash and Java are so heavily attacked now is that the core OS and browser combo are pretty secure, and the likes of Adobe and Oracle have never written much with security in the forefront.
MS's answer is Edge, but possibly a shade early for mainstream usage... ...though I'm trying to use it daily to get to understand it better.
Chrome's problem is both a) and b) above, but also includes c) - it utterly relies on a broken sandbox design for its security (on Windows. On unrooted Android, you have the inherent OS security to help).
FF was in a similar position, but hopefully has been through the worse of it. As a day to day browser, I'd recommend FF over Chrome from a security standpoint. Still suffers a) and b) though.
Opera is not really a browser, so I'll ignore that for now.
Safari on Windows, like all Apple software running on Windows, leads to some interesting security issues that are not technically the fault of Apple of MS, such as the now (partially) fixed blended vulnerability saving files with default settings, esp when taken with a).
I type this on Edge, as there are no ads on OOF to slow it to a crawl.
