FF has been one of the better full-featured browsers with generous amount of add-ons/plugins. There was no reason not to use it vs some less functional browser or some corporate data miner like Chrome. It still is, however some alternatives are catching up. Time will tell how it all shakes out as far as the battle between functionality, privacy, ad- and tracking-blockers, and people willing to build and maintain free browsers and plugins.
