Chromium Web Browser Overview and Features

Chromium is an open-source web browser project that was first released in 2008. It was created by Google as a fork of the open-source browser project WebKit.

Chromium is the base software for Google Chrome, which means that Chrome is essentially a version of Chromium with some proprietary features added on top. This allows Chrome to have a consistent user experience across different operating systems.

One of the key features of Chromium is its speed and efficiency. It has a lightweight design that makes it quick to launch and use, even on older computers.

Most GNU/Linux distributions have one or more Chromium packages available. This is great news for users who want to stay up-to-date with the latest browser technology.

Fedora users, in particular, have a few options when it comes to installing Chromium. They can enable rpmfusion and choose between the stock Fedora version, chromium-freeworld, which includes extra media codecs, and chromium-browser-privacy, which has some privacy-enhancing patches.

Take a look at this: Edge Chromium

Chromium is the overall fastest web browser engine available for GNU/Linux, outperforming other browsers in several areas.

The Brave Web Browser, based on Chromium, is marginally faster than the stock Chromium browser, demonstrating the potential for further optimization.

Chromium excels in WebGL performance and graphical performance in general, leaving other browsers behind in these areas.

Chromium doesn't have automatic browser updates like Chrome does.

If you're looking for a browser that stays up to date without any effort, you might want to consider using a different browser.

One notable absence in Chromium is the WidevineDRM module, which is used for digital rights management.

You'll also notice that Chromium lacks licensed codecs for popular formats like H.264 video and AAC audio.

If you're a fan of tracking mechanisms for usage and crash reports, you might be disappointed to find that Chromium doesn't have those features either.

Here are some browsers that are based on Chromium and don't have these features either:

Chromium is the overall fastest web browser engine available for GNU/Linux.

The Brave Web Browser, which is based on Chromium, is marginally faster than the stock Chromium browser.

Chromium is far ahead of other browsers when it comes to WebGL performance and graphical performance in general.

Chromium is the most feature-complete web browser available for Linux, making it a great choice for those who want a robust browsing experience.

However, it's worth noting that Chromium lacks some features that Firefox has, such as the ability to override website context menus by holding Shift and right-clicking on an image or video.

Chromium also doesn't have built-in web filtering capabilities, which can be a problem given the amount of junk that many websites load.

Fortunately, the Ublock Origin extension works very well with Chromium and is a must-have for anyone who wants a good browsing experience due to the abundance of unnecessary content on the web.

Chromium rules the web waves, having been the world's most popular browser since at least April 2016.

Microsoft's adoption of Chromium for Edge in January 2020 marked a significant shift, leaving only two different browser engines: Chromium's Blink and Firefox's Gecko.

Firefox's market share is around 7% in October, and its parent company, Mozilla, has been under serious financial stress.

Chromium's dominance is so great that Microsoft even admitted defeat, adopting Chromium to improve web compatibility and reduce fragmentation.

Apple's Safari uses WebKit, a predecessor of Blink, and has a very small share on personal computers, but a more respectable 17% on mobile.

The Chromium browser codebase contains over 32 million source lines of code, excluding comments and blank lines. This massive codebase is a testament to the complexity and scope of the project.

The browser's architecture is designed to be multi-process, which provides better responsiveness and security benefits compared to single-process designs. This was a deliberate design decision made by Google to improve the user experience.

Google's novel multi-process design required changes to the browser engine, which was originally based on Apple's WebKit. In 2013, Google officially forked its version as the Blink engine, which has since diverged from Apple's version.

The browser's user interface is designed to be minimalistic, which helps to improve performance and user experience.

Google's Chrome browser was designed with a multi-process architecture, which allows for better responsiveness and security benefits, but also increases memory usage.

This design decision was a deliberate choice to improve the user experience, especially when dealing with many browser tabs open at the same time.

The browser's user interface was also designed to be minimalistic, which is a deliberate choice to keep the focus on the content and not on unnecessary features.

The browser engine was originally based on Apple's WebKit, but Google's unique multi-process design required significant changes, leading to a fork of the engine in 2013.

Version 7 of Chrome boosted performance to twice that of prior versions, thanks to the addition of hardware acceleration.

App frameworks are a great way to build custom apps, and they're widely used in the industry. Chromium Embedded Framework, Electron, NW.js, and Qt WebEngine are notable app frameworks that embed a Chromium browser as their functional core.

These frameworks allow developers to create apps using HTML, CSS, JavaScript, and other web technologies. Spotify and Slack are two examples of apps built using this approach.

Developers can also use Chromium-based WebView components, such as Android System WebView and Microsoft Edge WebView2, to create custom apps. These components provide a similar way to make apps, but with a different implementation.

Here's a list of notable app frameworks and Chromium-based WebView components:

By using these frameworks and components, developers can create custom apps that are deployed on operating systems supported by Chromium.

Chromium is an open-source browser that offers more flexibility and privacy than Chrome, but it's not the only option. Chromium is ideal for advanced users, developers, and those who prioritize control over their browsing experience.

If you're looking for a more stable alternative to Chromium, you might want to consider the "Canary" channel. It's updated automatically and includes the full suite of Chrome or Edge features, but it can still be rough around the edges.

For those who want to try out the latest features of Chrome or Edge, the "Canary" channel is a great option. But if you're not comfortable with the possibility of instability, you might want to stick with the stable version.

Here are some alternatives to Chromium:

Chromium offers more flexibility and customization than Chrome, allowing unrestricted installation of third-party extensions.

You can install any extension you want, without being restricted to the Chrome Web Store. This gives you more control over your browsing experience.

Chromium doesn't track browsing data, ensuring greater privacy for users. It also prevents websites from collecting user behavior insights.

Here's a comparison of the two browsers in terms of customization and privacy:

Chromium receives frequent updates, keeping it current with new features and security patches. This is thanks to its open-source nature and a large developer community contributing to the project.

Many popular browsers, including Microsoft Edge and Opera, are built on Chromium's code. This means that Chromium's core components are widely used in various projects, contributing to browser innovation.

If you're not ready to dive into the world of Chromium, there are alternatives to consider.

Google's Canary browser is a more stable option, despite still being a bit rough around the edges. It's updated automatically and includes all the features of Chrome or Edge.

If you're on Windows or macOS, the Canary channel is a good choice. You can download Canary builds of Chrome here and Edge here.

Microsoft also offers Canary builds of Edge, which can be downloaded here. They're released almost every night, so you'll get a glimpse into what's coming next.

For Linux users, you can run the "Dev" channel build of Chrome or Edge instead of Canary.

Chromium's security is on par with Chrome and Edge because vulnerabilities are regularly patched, thanks to the efforts of Google's and Microsoft's engineers, as well as independent security researchers.

However, it's unclear when security fixes are added to Chromium's code, and bug fixes often hit the more unstable channels of Chrome and Edge before the Stable channel.

The lack of an update mechanism in Chromium is its single greatest security threat, as users won't receive security patches unless they manually download a later version.

Criminals have exploited this vulnerability by distributing modified versions of Chromium with malware or attack code, highlighting the need for users to stay on top of updates.

Chromium's lack of an update mechanism is its single greatest security threat. This means users must manually download a later version to receive security patches.

Vulnerabilities found by engineers and security researchers are regularly patched in Chromium. However, these patches may not be reflected in a user's copy of Chromium unless they manually update.

Criminals have taken advantage of this by piggybacking malware onto Chromium or distributing modified versions of the browser with attack code.

Chromium can have issues with video playback on certain systems.

A known issue with AMD graphics cards and Mesa 20+ is that video playback breaks due to a gstreamer-vaapi issue.

To work around this issue, you can create a $HOME/.drirc file to disable 10-bit colour-support for the chromium-browser process.

Alternatively, you can put the workaround in a file called /usr/share/drirc.d to make it system-wide.

Chromium also lacks some features compared to Chrome and Edge.

One notable feature that Chromium lacks is automatic updates, which means users must download newer versions manually to get security fixes and feature upgrades.

This can be a hassle, especially for users who rely on the latest security patches.

Another feature that Chromium lacks is support for the Widevine digital rights management (DRM) module, which is used by Netflix and other services.

As a result, Chromium cannot play Netflix content.

Google Chrome and Google Chromium share some similarities, but they also have some key differences.

Chromium is more prone to crashes, even compared to basic versions of Chrome.

In terms of features, Chromium lacks the update mechanism, built-in support for multiple technologies, and digital rights management (DRM) components that Chrome provides.

Here's a summary of the key differences between Chrome and Chromium:

When choosing between Chrome and Chromium, it's essential to consider your specific needs. Generally, most people prefer using Chrome due to its ease of use and extensive add-ons.

Chrome offers a better Flash player and allows viewing more online media content, such as Netflix videos on Linux, which require H.264 support for HTML5 video. Chromium, on the other hand, does not include this feature.

Open-source developers may prefer using Chromium if they plan to modify the source code frequently. This is because Chromium allows Linux distributors to package a browser almost identical to Chrome, making it a suitable choice for their needs.

For another approach, see: Google Drive on Linux Mint

Since Chrome and Chromium can be operated simultaneously, you can split your requirements and execute functions on the browser most suited to them. This flexibility makes it possible to use both browsers together, depending on the task at hand.

If you're a Linux user, you may want to consider the following:

Chromium provides the vast majority of source code for Google Chrome, but there are some key differences between the two browsers.

One of the main differences is that Chromium lacks the following Chrome features: automatic browser updates, API keys for some Google services, the WidevineDRM module, licensed codecs for the popular H.264 video and AAC audio formats, and tracking mechanisms for usage and crash reports.

Chromium is also missing some of the features that make Chrome more user-friendly, such as built-in support for multiple technologies and digital rights management (DRM) components to play copyrighted content.

Here's a summary of the key differences between Chrome and Chromium:

Overall, Chrome and Chromium have some key differences that set them apart from each other.

Chromium is compatible with a wide range of operating systems, including Windows, macOS, and Linux. This makes it a versatile choice for users.

It's also worth noting that Chromium is an open-source browser, which means that it's free to use and modify. This has led to the development of many derivative browsers, such as Google Chrome.

One of the key benefits of Chromium's compatibility is its ability to run on older hardware, making it a great option for those with older computers or laptops.

You can run Chrome and Edge on the same system, and it's no big deal to have both installed at the same time.

In fact, it's similar to running different channels of Chrome and Edge on a single Windows PC, like running the "Canary" build of Chrome alongside the "Stable" version.

This means you don't need to uninstall Chrome to add Chromium to your machine, and you can remove Chromium just like any other application.

The various channels of Chrome and Edge work independently, so you can have multiple versions running simultaneously without any issues.

Linux is a great choice for running Chromium, and the good news is that it's widely supported.

Each Linux distribution has its own repository with a stable version of Chromium, so you can easily find a compatible version.

You can check the Linux part of the documentation for more information on how to get started.

The 64-bit and 32-bit versions of Linux are both supported, giving you a range of options to choose from.

Just remember to check your Linux distribution's repository for the latest stable version of Chromium.
