Chrome : the privacy breaches seem to be large enough to actually become a security threat as well. Is that a fair statement?
Firefox : seemed pretty good to me until I read this article https://madaidans-insecurities.github.io/firefox-chromium.html. It claims that Firefox is more insecure than Chrome/Chromium, in large part because of a weaker sandboxing mechanism. Even if this mechanism seems to be catching up, this points to a significant lag in Firefox's security
Safari : is it secure?
Chromium : it seems to be the best bet to me, because it seems to contain the best security mechanisms, without the Google spyware. However: 1) it does not seem to provide an automatic update system 2) I read that it's unstable because it contains bleeding edge code. That actually sounds like it's less safe than chrome because of that => is there a way to know which Chromium version Chrome is using, and just using this version?
I am grateful for any thoughts.
