Mozilla's Firefox climbed above 20 percent market share for two weeks last month, but ended October just under the milestone, a web metrics has said.

During two separate weeks last month, Firefox exceeded 20 percent share, said Net Applications. For the week ending October 5, the open-source browser averaged exactly 20 percent, while for the week ending October 26, Firefox accounted for 20.06 percent of the browsers used to connect to the thousands of sites Net Applications monitors for clients.

For the month as a whole, however, Firefox's share averaged a close-but-no-cigar 19.97 percent, a jump of nearly half a percentage point over September. That month, Firefox lost ground because of the introduction by Google of its own browser, Chrome. Firefox has now regained what share it lost, and then some.
