I started using Firefox for its adblock addon on W98 with v1.0.3? but my computer at the time couldn’t handle it (433mhz,96MB RAM) so I used Maxthon.
When I got a new computer with 256MB RAM (later 768) I switched over to Firefox 1.5.0.14? near full time because of the amount of customization.
I was saddened by v53+'s lockdown & eventual removal of XUL API’s for customization & am still waiting to recover functionality to this day with v115.

On mobile I used Opera in ~2007/2008 on a feature phone.
My first android phone in 2011 (Transform, a low end 2.1 Eclaire slider with 256MB RAM) in 2012 didn’t cut it CPU arch & RAM wise so I used Opera & Dolphin because of RAM.
It took until I got a SGS4 (2GB RAM) to switch over to Firefox & I haven’t looked back.

There is a difference between keeping tabs on someone & stalking/harassment.
I don’t like the Elon jet tracker stuff, I’m more a fan of privacy.
