I use to use firefox only .. got hit to many times and cost me a 900$ PC laptop ... i used virus and malware secuity suites back then Norton to malware bytes .. crap malware still got in .. The last crap that got my laptop even came back an hour after reconfiguring it back to original .. pop up pop up pop up virus BS every 2 minutes . No idea what the hell it was but after spending days reconfiguring and loading my business programs . Well the laptop hit the floor and I went directly to the store and bought a new laptop .. I never went back to firefox and found duck duck go , and used it now for many years ,, safari is my second browser and never had a problem . I use it in private mode . Also went to apple devices.
