Coming through with Firefox 82 – Mozilla Hacks

As October ushers in the tail-end of the year, we are pushing Firefox 82 out the door. This time around we finally enable support for the Media Session API, provide some new CSS pseudo-selector behaviours, close some security loopholes involving the Window.name property, and provide inspection for server-sent events in our developer tools.

This blog post provides merely a set of highlights; for all the details, check out the following:

Inspecting server-sent events

Server-sent events allow for an inversion of the traditional client-initiated web request model, with a server sending new data to a web page at any time by pushing messages. In this release we’ve added the ability to inspect server-sent events and their message contents using the Network Monitor.

You can go to the Network Monitor, select the file that is sending the server-sent events, and view the received messages in the Response tab on the right-hand panel.

For more information, check out our Inspecting server-sent events guide.

Web platform updates

Now let’s look at the web platform additions we’ve got in store in 82.

Media Session API

The Media Session API enables two main sets of functionality:

  1. First of all, it provides a way to customize media notifications. It does this by providing metadata for display by the operating system for the media your web app is playing.
  2. Second, it provides event handlers that the browser can use to access platform media keys such as hardware keys found on keyboards, headsets, remote controls, and software keys found in notification areas and on lock screens of mobile devices. So you can seamlessly control web-provided media via your device, even when not looking at the web page.

Reference Variable in Java

Before We Started with the Reference variable we should know about the following facts.

**1. **When we create an object(instance) of class then space is reserved in heap memory. Let’s understand with the help of an example.

Demo D1 = new Demo();

Reference Variable

Now, The space in the heap Memory is created but the question is how to access that space?.

Then, We create a Pointing element or simply called Reference variable which simply points out the Object(the created space in a Heap Memory).

Heap Memory

**Understanding Reference variable **

1. Reference variable is used to point object/values.

**2. **Classes, interfaces, arrays, enumerations, and, annotations are reference types in Java. Reference variables hold the objects/values of reference types in Java.

3. Reference variable can also store null value. By default, if no object is passed to a reference variable then it will store a null value.

**4. **You can access object members using a reference variable using **dot **syntax.

.<instance variable_name / method_name>

Firefox 81 Release Kills High-Severity Code-Execution Bugs

Mozilla patched high-severity vulnerabilities with the release of Firefox 81 and Firefox ESR 78.3, including several that could be exploited to run arbitrary code.

Two severe bugs (CVE-2020-15674 and CVE-2020-15673) are errors in the browser’s memory-safety protections, which prevent memory access issues like buffer overflows. CVE-2020-15674 was reported in Firefox 80, while CVE-2020-15673 was reported in Firefox 80 and Firefox ESR 78.2. Firefox ESR (Extended Support Release) is a Firefox version that’s based on an official release for desktop, for use by organizations who need extended support for mass deployments.

“Some of these bugs showed evidence of memory corruption, and we presume that with enough effort some of these could have been exploited to run arbitrary code,” according to a Mozilla Foundation security advisory, released on Tuesday.

Scope of a Variable In Java [With Coding Example]

Introduction

Programmers define the scope of a Variable in Java that tells the compiler about the region from where a variable is accessible or visible. The scope of a variable in Java is static by nature. It means we have to declare it at compile time only. In this article, you will learn about the scope of a Java variable along with its types
