About Plugins in Chrome
Description of the command about: plugins in the Chrome browser and comparison of the list of add-ons of other browsers.
about:plugins
When you type this command in the address bar, the browser displays the list of modules added to the browser, which are most often available in the form of additional plugins.
List of plugins in Chrome
- ActiveX plug-in.
- Google Gears.
- Google Gadget Plugin.
- Adobe Acrobat.
- Google Update.
- Google Updater.
- Windows Presentation Foundation.
- Silverlight Plug-In.
- Shockwave Flash.
- Default Plug-in.
There are ten plugins. We can see by comparing with other browsers that Google offers two more modules: ActiveX and Google Gears and it does not include Java by default.
Details of plugins
ActiveX (Option)
Used to recognize ActiveX objects from Microsoft. The most common is XMLHttpRequest which is the basis of Ajax but it is an ActiveX object in Internet Explorer and a browser object otherwise.
To check how the XMLHttprequest object works with Chrome, two test pages were put online:
- Ajax test with ActiveX. In this test the XMLHttpRequest object is created only in the form of ActiveX object.
- Ajax test standard. In this test, it is only an XMLHttpRequest object compliant with the W3C standard that is created.
These tests show that with Chrome qu'ActiveX does not create an XHR object, only the standard format is recognized. Only Internet Explorer passes the first test.
Note that in practice both modes are used simultaneously for compatibility with all browsers.
Flash
Runtime from Adobe to display Flash pages or games.
Remoting Viewer
Work with the the Remote Desktop application (which control remotely your computer). Disable this plugin if you do not use this app.
Native Client
Allow to run in the brower applications in native code, so faster.
Chrome PDF Viewer
Used to display PDF files with the browser.
Google Update
For updates to the browser.
Windows Presentation Foundation
A graphical interface system in .NET, which manages the processing of XAML.
Silverlight Plug-in
The Microsoft framework to facilitate the creation of online applications. The version 1.0 of Silverlight, more portable, does not have widgets but has graphics functions and supports XAML.
Google Gears (Option)
The Google Gears plugin allows Web applications to work offline.
One option in the Under the hood tab in the options panel allows you to specify how each site can use Google Gears.
Google Gadget (Option)

- Adobe Acrobat
- Google Gadget Plugin.
- Google Update.
- Java Platform.
- Shockwave Flash.
- Silverlight Plug-In.

They are almost the same modules, even if some could have been added to the browser. Additional Java support.
The differences are the ActiveX and Gears plugins which are not present in Firefox.
Comparison with Opera
There are also the same plugins without ActiveX, Gears, plus Java.
Silverlight is part of the list in recent versions of Opera.
Comparison with Internet Explorer
The Microsoft's browser does not recognize the command.
But you can have the list from the browser:
- Go to Tools -> Internet Options.
- In History, click Settings.
- Click on View objects.
Not all plugins appear in the list.
Comparison with Safari
Although it shares technologies with Chrome, Safari does not support the command, but you get the list from the options.
- Click on Help.
- Click on Install modules.
This list is displayed:
- Google Gadget Plugin.
- Apple Java Plug-In.
- Shockwave Flash.
- Windows Presentation Foundation.
- Adobe Acrobat.

- Silverlight Plug-In.
This is the same list as for Firefox.
Conclusion
The particularity of Chrome is the integration of Gears by default and ActiveX (which is also part of Internet Explorer). It is a browser that is ready for Web applications with plugins as it is in its design.
Obviously the list of add-ons will evolve with what the user will install in the future.
