I was just reading this section of the GOS usage guide and stumbled upon this paragraph:
Even in the desktop version, Firefox's sandbox is still substantially weaker (especially on Linux) and lacks full support for isolating sites from each other rather than only containing content as a whole. The sandbox has been gradually improving on the desktop but it isn't happening for their Android browser yet.
So, according to this Firefox/Gecko based browsers have a substantially weaker sandbox than chromium based browsers especially on Linux systems. Personally, I use Firefox as a daily driver simply because I prefer diversity over monopolies such as chrome and chromium based Browsers (plus, a strong competitor is always good for balance and a healthy market situation).
But this is only feasible as long as the trade off in security features (and others) is acceptable. So, my question here is: Are there any links/sources that verify the statement above? I do not doubt it, in general, but I prefer to read the data/research myself before I accept it as a given. It's not really a trust issue, but I would like to understand it.
