Mozilla is in bed with Google. I use brave because:

* it has reasonable way of funding, crypto may suck, but it is believable they will not sell my data

* anonymous bookmark sync with multiple profiles. With Chrome and Firefox I have to sign up for each sync.

* Chrome based debug tools

* It is usable without any plugins. In some environments I do not want to install some questionable plugins, that may change ownership anytime! (It is already named "Ublock Origin", ownership already changed )

* Proprietary Video Codecs support out of the box on Linux. Some distros do not have it, and I do not want to enable community repos.
