Statistics show that last month, the Firefox browser had a strong grip over 20 percent of the market share within two different weeks, while the rest of time the percentage was always very close to that threshold.

Net Applications has recently revealed that the browser managed to exceed the 20 percent market share the week that started October 5, the same time Microsoft’s browser Internet Explore began to lose some points.

On a related topic, the engineers at Mozilla have released a new privacy browsing mode feature to Firefox, which put the open-source browser in line with Internet Explorer, Apple Incorporated’s Safari and Google’s Chrome that have already added such a tool to their users’ browsing experience.

The privacy feature was launched Monday, being aimed at giving Internet users the option to prevent Firefox from capturing the latest URLs they have visited, which also keeps others who happen to use the same computer from seeing what the former have been browsing the Web for.

Nevertheless, Firefox has been offering users a privacy plug-in for a while now, called Stealthier, the only difference that the new tool brings being that it is already built into the browser, so a plug-in is not necessary any more for those who don’t want people sneaking a virtual peak at their Web habits.

The 20 percent market share Mozilla’s Firefox has come into last month has rendered it the second-most popular browser in current use worldwide, following Microsoft’s Internet Explorer, whose market share amounts to 71 percent.
