The Most Popular Browser: 2012 vs 2025
https://www.reddit.com/r/MapPorn/comments/1k8kngc/the_most_popular_browser_2012_vs_2025/
I use Firefox and modify the look using a file called: userChrome.css
One of the reasons i went with vivaldi is that one of vivaldi’s founders was the guy who developed and owned Opera.
I helped beta test Opera back in the day.
You could run it off of a 1.44 floppy.
Had to pay for Opera for awhile...I bailed after they went chrome and released Opera 15
