If you are a Firefox fan than you must have experienced periodical out-dating and temporary unavailability of your favorite extension every time you update your browser. Same thing is going on with the upcoming release of Firefox which is Firefox 57. It will release from November 2017 but if you are on beta channel you can upgrade to it now, from October 2017. If you have upgraded you will notice many extensions are not compatible and since disabled by-default and there is no option available to enable them. These extensions are listed as "Legacy Extensions" which used to be listed as incompatible extensions in previous versions. From Firefox Official Blog: In the past, extensions often stopped working each time a new version of Firefox was released, because developers had to update them every six weeks to keep them compatible. Since extensions could also modify Firefox internal code directly, it was possible for bad actors to include malicious code in an innoce...

Java Development Kit (JDK) 9 Download Link: http://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848520.html Java SE 9 At JavaOne 2011, Oracle discussed features they hoped to release for Java 9 in 2016. Java 9 should include better support for multi-gigabyte heaps, better native code integration, a different default garbage collector (G1, for "shorter response times") and a self-tuning JVM. In early 2016, the release of Java 9 was rescheduled for March 2017, later again postponed four more months to July 2017, and changed again to be finally available on September 21, 2017, due to controversial acceptance of the current implementation of Project Jigsaw by Java Executive Committee, which led Oracle to fix some open issues and concerns, and to refine some critical technical questions.
