Netscape became bloated, that’s the truth.
Back in those old days when Netscape and IE were fighting for dominance, every new release of Netscape or every new release of IE would inch them further ahead of the other. Then IE became a bit bloaty and people started going back to Netscape, then Netscape became really bloaty and everyone decided to just stick with the built-in browser in Windows.
Honestly, I miss the days when I could just be browsing files and type in a www. address at the top of my browser and that file explorer window became a web browser.
