One reason could be that active users of the browser are annoyed at the constant useless UI changes that break their workflow.
My reason is that I don't like Mozilla's false-advertising as a privacy-protecting browser which is absolutely not the case and gives a false sense of security to less savvy users that aren't aware that they need to change many settings and install specific third-party extensions to reach a semblance of privacy.
I would like to have some insights, if possible at the level of privacy reached by Firefox compared to Chrome and what the best alternative for privacy is overall in which I can keep things usable.
Honest question, since I am not into this research that much. I am using Firefox right now on the basis that Chrome prostitutes user data as much as possible.
Chrome is terrible as it sends extra metadata to Google domains which can be used to track you. It however doesn't come as a surprise as it's a browser made by an advertising company notorious for tracking users.
Firefox by default is on par with other mainstream browsers but at least most other browsers don't shout "privacy!" at every possible opportunity.
Firefox with some configuration options changed and uBlock Origin is very good but changing configuration from the defaults exposes you to extra fingerprinting, so it's a double-edged sword.
