There is a brewing war between the owners of the browsers mainly Google Chrome, Microsoft Internet Explorer 9, and Mozilla Firefox 4.

As per the Mozilla's noisiest hominid, Asa Dotzler, Firefox 4 is leading the chart with 5% of the Web browser global usage share followed by 1.5% share of two-week old internet Explorer 9(IE 9).

Close on the heels of Google’s security update for its Chrome browser, Mozilla has recently released one more, probably the last, update for Firefox 3.6 – the Firefox 3.6.14 – to address 10 vulnerabilities in the browser, including eight flaws that have received a ‘critical’ rating on the basis of the security risks associated with them.

It has just been 10 days that Mozilla happened to release its Firefox 4 Beta 9, and now it is back with the latest Firefox 4 Beta. Released on Tuesday night, it is being said that Firefox 4 Beta 10, as with Beta 9, are pretty sparse.

In a move aimed at dealing with the irksome “behaviorally targeted advertising” system, which has become quite common on the Web, Mozilla and Google recently announced the addition of “do not track” tools to their Firefox and Chrome browsers respectively.

In response to the ‘Do Not Track’, lists which had been proposed by the U. S. Federal Trade Commission, Google and Mozilla are said to have made an announcement regarding their new browser initiatives. As per these new changes the users will now be permitted to opt out of having their online activities being trailed by online advertisers.

In their recently-announced new browser initiatives, Google and Mozilla disclosed that they have plans in place for implementing `Do Not Track' privacy features on their respective Chrome and Firefox browsers; thereby giving the users the option of opting out of having their activities tracked by online third-party advertisers.

In a recent blog post, Mozilla said that it has barred a Skype extension for Firefox because the extension allegedly not only slowed page-load times dramatically, but also happened to be the cause of 40,000 browser crashes a week.

The new Firefox 4 Beta, which Mozilla released to the public on January 14, boasts notably speedier start-up time, high-speed rendering of complex animations, and enhanced bookmarking; and, thereby emphasizes on speed for users to play with on Windows, Mac and Linux.

In what marks yet another advance for Mozilla in the direction of launching the final version of its open source browser next month, the company Friday announced the release of Firefox 4 Beta 9.

According to the statistics revealed by StatCounter, Mozilla Firefox is ruling the roost in the browser arena in Europe; marking a notable change from the scenario some time back when Microsoft's Internet Explorer (IE) was Europe's most dominating browser.
