i use firefox, both on PC and mobile! while mozilla corp has definitely made some bad decisions in the past couple years (why they'd throw in ai chatbot integration when most of their users are privacy-minded is still beyond me LOL) neither chrome or opera have been as reliable, lightweight and responsive on my low end devices as firefox has been - which is really huge as someone who tries to replace their electronics as little as possible. besides, being able to send tabs to and from either platform makes keeping track of things a lot easier.
