The chance is however relatively good that some developers have already created extensions for popular web services. This article will look at five Google Chrome extensions for popular Google web services including Gmail and Google Reader.

Gmail Checker

Gmail Checker is a simple extension that displays a button in the Google Chrome menu bar. This button displays the number of unread email messages in the Gmail account which makes the extension useful as the user will be notified about new Gmail messages without having to visit the Gmail website first.

Google Reader Checker

This is from the same developer who developed the Gmail Checker extension for the Chrome web browser. It is therefor not surprising that it works exactly like that extension. It will display a new button in the Chrome menubar that shows the count of the unread news items in Google Reader. [link]

Google Tasks

The Google Tasks add-on integrates Google Tasks into the web browser by allowing the user to access the tasks directly from within the web browser without having to open the Google Tasks website. [link]

gPDF

This extension allows the user to open pdf documents directly in Google Docs. There are two advantages of this method. First, no pdf reader needs to be installed on the computer system to read pdf documents and second, it will reduce the chance that the document exploits security vulnerabilities in the installed desktop pdf reader.

Google Wave Checker

A basic extension that will display the unread Google Wave messages in the Google Chrome statusbar. [link]

Verdict:

Extensions are finally beginning to appear in greater numbers for the Google Chrome web browser but are hardly a match for the incredible amount of extensions for the Firefox web browser. It is likely that this is not going to change in the near future. The first step to make extensions more popular to both developers and end users would be to add extension capabilities to the public version of the Google browser.
