Why would anyone use Netscape if they can still use the much more traditional IBM WebExplorer

Yes, every device I tested so far (apart from Netscape on windows 3.1)

There’s a nice browser run and open source alternative to airdrop called Snapdrop. It uses web rtc to transmit data from device to device directly and can be self-hosted. I use it to transfer data between my Mac and my windows pc as well as my steam deck.
