This week at the Netscape blog, I wrote about the allowances we’ve made in Netscape 9 for installing extensions targeted at Firefox 2:
“Since Netscape 9 will share an architecture with Firefox 2, it is very likely that most Firefox 2 extensions will work in Netscape 9 without modification. This is why Netscape 9 will allow you to install extensions that list Firefox 2 as a compatible version but do not explicitly list Netscape as well. This feature will give all users of Netscape 9 immediate access to Firefox’s wealth of custom extensions without having to wait for each author to update the extension’s compatibility file.”
