I can't imagine that there would be such a writeup. Even just trying to understand the security framework of one browser is a gargantuan task.
As for Chrome being a real issue, some points off the top of my head:
- Its extension store breeds out malware in regular intervals (feels like there's headlines about that at least every other month).
- Pretty bad autofill exploit that was left unfixed for years: https://github.com/anttiviljami/browser-autofill-phishing
(Might've been fixed in the past year, I haven't checked, but I doubt it.)
- Chrome Sync is not end-to-end-encrypted without the use of a second password, which effectively means that it is unencrypted for 99.9% of Chrome users. Google also actively uses this data, weaving your browsing history into the profile that they keep of you. So, if they ever have a data leak, a lot of data is going to come from people using Chrome, too. The NSA/CIA/FBI also tap into this data, possibly using it for cyber war attacks, so if you live in a country other than the USA, you're making yourself a prime target and an easy target by inputting this data through Chrome.
