Chrome was the world's most used browser on March 16th

"It may only have been for a single day, but according to StatCounter Google Chrome finally managed to surpass Internet Explorer to become the world’s most used web browser.
On Sunday, March 16th, Chrome temporarily slid ahead of IE with a share of just over 32%. Weekends have historically seen a downturn in IE usage. As people wind up their work week and spend more time on their home computers, they’re more likely to use an alternative browser. IE still maintains a dominant position in corporate environments, but that too has begun to change.
Over the past year, Chrome has steadily climbed while IE continues to fall. Initially folks thought that Google’s rapid rise was being fueled by Firefox defections, but Mozilla has only seen a drop of about 5% — while IE is down more than 10%. A second chart from StatCounter tells the story: those IE peaks and plateaus are clearly on a downward trend.
It’s important to note that StatCounter doesn’t correct its usage figures to account for one detail that could skew the numbers slightly in Google’s favor. Speculative pre-rendering (which arrived  in the Omnibox in Chrome 17) and Instant Pages support (which appeared in Chrome 13) both cause Chrome to send additional traffic to web servers that may never result in an actual visit from a user."

Google pays approximately $100m per year to Mozilla

"Google has renewed a deal to remain the default search engine within Mozilla's Firefox web browser.
The non-profit foundation said it had "negotiated a significant and mutually beneficial revenue agreement" with Google for the next three years.
Some analysts had predicted Google would back out of the deal as it tries to grow the market share of its Chrome browser.
Mozilla relies heavily on the income generated by search partnerships.
[...]
In its accounts for 2010, the Mozilla Foundation said it earned $121.1m (£77m) from agreements with Google, Microsoft and others. The Google agreement was thought to make up about 85% of that amount."

Internet Explorer has less than 50% share of all web browsing

"Internet Explorer can no longer claim more than half of the web’s traffic, as of October, ending more than a decade of the default Microsoft browser’s reign.
Safari’s hold on 62.17% of mobile traffic has reduced IE’s overall share of web browsing, despite still claiming 52.63% of desktop traffic, according to Netmarketshare.com.
The Microsoft browser’s diminishing share (49.6%) reflects its near absence from the realms of mobile and tablet, which now make up 6% of web traffic. However, chances are, you gave up on IE long enough ago that this milestone makes you more curious as to who actually still uses the browser.
As of October, Firefox is the second most popular web browser, accounting for 21.20% of traffic, followed by Google Chrome and Safari, which account for 16.60% and 8.72% respectively.
Chrome, which recently celebrated its third birthday, experienced the most expansion in October, increasing its share of the desktop market 1.42%.
Safari, the default browser in Apple’s iPhone and iPad, continues to increase its dominance over the mobile web, gaining 6.58% of the market. Safari’s share is increasing faster than the iPhone’s, probably due to how much mobile traffic is now driven by iPads."

The mobile browser Opera Mini has over 100m users

"In this month’s State of the Mobile Web report, we are highlighting a major milestone in the growth of the mobile Web. When we combine the number of people who used the Opera Mini browser (90.36 million) in January with the approximate number of Opera Mobile (15 million) users in January, we get over 100 million people who are using Opera browsers on their handsets. That number only includes people who have downloaded the public version of the Opera Mini browser; it does not include people who use Opera Mini instances that are preinstalled on phones by operators. As such, 100 million is actually an underestimate, but we are not concerned, as that number will be eclipsed shortly. Opera Mini’s increasing growth rate over the last five years has been nothing short of astounding, and our expectations are high for 2011 and beyond.
Consider these numbers:
Between January 2006 and January 2007, the number of Opera Mini users increased by 1.9 million.
Between January 2007 and January 2008, the number of Opera Mini users increased by 5.3 million.
Between January 2008 and January 2009, the number of Opera Mini users increased by 12.4 million.
Between January 2009 and January 2010, the number of Opera Mini users increased by 29.8 million.
Between January 2010 and January 2011, the number of Opera Mini users increased by 40.6 million.
Based on that growth trend, we think there is legitimate cause to say that mobile web browsing is the wave of the future, a future we are helping to create via our mission of providing the best Internet experience on all devices."

2 Billion add-ons have been downloaded for Firefox

"Mozilla is celebrating another significant milestone for its flagship Firefox browser – two billion downloaded add-ons.
In an announcement on its rockyourfirefox web site, the company thanked its developers and loyal users, and talked up the customisation features of the browser.
“[This] feat was made possible by the huge community of people like you who use Firefox add-ons as well as the thousands of developers who make the add-ons you use,” wrote Julie Shin Choi, a Mozilla marketing executive.
“Over the years, we remained dedicated to building features and products that make Firefox the world’s most customisable web browser for consumers and developers."
Mozilla passed the one billion mark in November 2008 and at that time predicted that it would take around three years to double that number. However, it beat that estimate with ease, and Choi predicted that another major milestone would be reached soon."
