I just hope Ofcom will have a similar idea for the UK. Currently you only have a “universal service obligation” for 10Mbps, and if you can be provided by 4G then Openreach doesn’t have to upgrade your old copper line. Large areas of my city are still copper only.
The closest you can get is the Seamonkey browser, which forked off the old Mozilla Application Suite that Netscape 6/7 was based on. The last version of Netscape 9 was just a rebranded Firefox 2.x.
