Mozilla had process based isolation (mainly due old code base). That is far less effective. Some things like GPU access are not sandboxed at all!
>Google remains the default search engine provider inside the Firefox browser until 2023 for an estimated $400 million to $450 million per year.
Mozilla is a multibilion corporation. They DO have resources for proper rewrite in Rust. How they spend their money is another thing!
Old code base was good excuse in 2016! Brave Software Inc is much smaller company, and they do advanced stuff like their own search engine!
Which extension authors are shady? I am mostly sticking to ublock origin, but this is the first time I hear that accusation.
Plus several extensions were just sold to highest bidder!
Ublock Origin installed from Firefox Extension Web Store. I have no idea how this was verified and distributed. I do not trust webstore as a channel. Also user may easily click on "Unblock" or "Unlock" and get something completely different.
If this extension came from my Linux distro package, or bundled into Firefox binary, I would trust it.
With Brave I have no need to use extensions. Everything is bundled and can be enabled via about:flags.
Try to actually compile that bloody thing, before you write "software to be fully modifiable by any person using tools that are easily, freely available and accessible"
Even Ubuntu team gave up on compiling their software, and are serving mainstream binaries from Mozilla!
Brave has some shady stuff, but that is easy to disable in configuration. And under-hood they follow security patches pretty well, have good security and stuff like 3D acceleration just works!
And you do not need 10 browser extension from some shady authors, that has full access to your browsing data!!!
