There are a lot of decades old embedded systems out there. Every so often you hear about a big company still relying on floppy disks and other old tech, including major railways and airplane companies. Having the source code will help with debugging better than having to disassemble or other reverse engineering.
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.
Even though it is the last official version for it, good to see they are still fixing Windows 7 bugs.
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.
