Being a cross browser testing cloud, we are always looking out for the release of new browser versions and adding them to our platform so you could ensure cross browser compatibility of your website. This week we have expanded our browser collection by adding the latest stable & beta versions of multiple browsers to our real time testing.

You can now perform cross browser testing over:

These browser versions can be found in our real time testing.

Test On Google Chrome 84 & 85 Beta

Google Chrome 84 released on July 14, 2020 and has a version 8.4 of the V8 JavaScript engine. You can find the list of changes from th V8 blog. I am going to point out some of the exciting features that might concern your cross browser compatibility.

What’s New In Google Chrome 84?

Google Chrome 84 has introduced “App Icon Shortcuts” using which users will be able to perform basic actions of an application by right clicking on the icon from desktop or long pressing the icon from an Android.

You can easily incorporate App Icon Shortcuts in your PWA by invoking a shortcuts property.

Web Animations API support just got better in Google Chrome 84.

Web Animations API

You can now leverage animation.ready & animation.finished with the latest Chrome 84. The Chrome 84 also promises better performance as the browser can now perform cleanup and remove old animations to save up the memory. For more information, read this article on Web Animations API improvements in Chrome 84.

Deprecations and Removals In Chrome 84 – @import rules if incorporated within the replace() call will now throw an exception. Also, TLS 1.0 & TLS 1.1 has been deprecated in Chrome 84.

You can find all the deprecations & removal in the ChromeStatus.com.

What To Expect From Google Chrome 85 Beta?

The @property comes into the play.

CSS Houdini has been a game-changer for the CSS world. As it presented a set of low-level APIs that allows developers to relay to the browser how it should read and parse custom CSS defined on your website, even if those features are not natively implemented by the browser vendor.

One of the most pivotal API offered by CSS Houdini is the CSS Properties and Values API which allows developers to define custom CSS properties with default values, type checking, and the ability for properties to be inherited. This API was first supported in Google Chrome 78 through CSS.registerproperty(). This can now be invoked through stylesheets with the help of @property.

Read more about this from @property: giving superpowers to CSS variables.

For more information, refer to Chromium Blog.

Test On Mozilla Firefox 78 and 79 Beta

Test On Mozilla Firefox 78

Let us look at some of the pivotal changes and fixes brought in the latest version of Mozilla Firefox.

Picture-in-picture support is now available in the latest version of Firefox.

An improved WebRTC for smooth web-conferencing and video-calling experience as the screen saver won’t be interrupted anymore.

Firefox 78 has kept a major focus on improving accessibility. In previous versions of Firefox, the Screen readers used to lag when a user would open their microphone, camera, or share their screen. This has been taken care of in Firefox 78. For users with migraine & epilepsy, Firefox 78 has reduced numerous animations that triggered on a motion like a tab hover, search bar expansion, etc.

Like Google Chrome, Mozilla Firefox has also deprecated TLS 1.0 & TLS 1.1. With that said, let’s take a look at some of the differences from cross browser compatibility perspective between Chrome 84 & Firefox 78.

Test On Opera

After providing built-in support for Instagram, Telegram, Facebook Messenger, WhatsApp, and VKontakte in earlier releases. Opera 69 desktop browser now allows users to have a better twitter experience. The latest browser has a built-in twitter on the browser UI.

There is also an improved visual tab cycler which now offers more tabs in the view. You can trigger the Visual tab cyler by using Ctrl + Tab simultaneously.

There are also improvements made to Workspaces and you now get a new weather widget in Opera 69.

Opera 70 beta is also based on Chromium 84 and offers better UI with workspaces with the convenience to easily access closed tabs. You can also dig deeper into search history with a wider search field panel inside History. The search within tabs has also improvised based on the content.

Test On Microsoft Edge 84

Microsoft Edge has been back in popularity ever since it incorporated a Chromium-based browser engine. In fact, if we look at the last 3 months then Microsoft Edge ranks number 2 in the browser market share after Google Chrome. With Microsoft Edge having 8.07% market share and Google Chrome dominating the chart with 70.19%. However, Edge is number 2 and that happened only after the Chromium Edge was introduced in January 2020.

Test On Microsoft Edge

Now since both Microsoft Edge 84 & Google Chrome 84 are based out of the same Chromium version. Are there any rendering difficulties or cross browser compatibility issues between the two?

Well, the majority of the features are equally supported by both browsers however there are a few differences.

 Microsoft Edge 84

So what does the new Microsoft Edge have to offer?

Microsoft Edge 84 offers full-screen mouse support where users can leverage the mouse to switch tabs, access the address bar, and more while they are in full-screen mode.

Users can now nickname the saved credit or debit cards for convenient online purchasing.

TLS 1.0 and TLS 1.1 are disabled by default. However, users can re-enable them according to SSLVersionMin policy which won’t be available after Microsoft Edge 88 goes live.

Microsoft Edge 84 allows users to listen to PDF content while browsing through Read Aloud for PDF. The feature also helps visually impaired users facilitate easy learning.

Other than that there have been few policy updates and few policy deprecation. Read them all from Microsoft Edge stable channel release notes. You can now perform tests even on outdated versions of Edge like selenium testing on edge 18 for your website.
