I bet that unemployment has a lot to do with it - the November U-E rates are in and although they aren't good numbers, the fact that there's more people at home, browsing than at their offices since the lay off, means that FF's share rose and IE went down.

IE gets it's biggest use during the day when people, who might still be employed, are in their cubicles, tapping and clicking on what their company's boss thinks is the best thing since round wheels.

This time below the 70% market-share, IE is slowly slipping into the mire-y deep as FF gloms onto new (or the newly-unemployed-and-now-at-home) surfers.

It's speculated the new IE8 won't do so well either; it's not an earth-shaking release like a new version of FF would be, nor is it well greeted in the pres either.

Don't forget that Safari takes a small, albeit decent chunk too, outta the M$ thigh.

To bad, Billy, looks like dumpster-diving is your next sport of choice.

According to statistics from the US Department of Labor, the unemployment rate in the US rose from 6.1 percent to 6.5 percent during October. Last month's numbers are due out at the end of this week.
Of the top four non-Microsoft browsers, only Opera's flagship dropped in share during November; it fell to 0.71 percent from October's 0.75 percent.

"The more home users who are online, using Firefox and Safari at home rather than IE, the more those browsers' shares go up," he said. With November including the Thanksgiving holiday in the US and more weekend days this year - 10 such days versus an average of 8.7 per month - users were at home more than usual.

Net Applications' data has consistently shown that Firefox and Safari usage climbs on weekends and after work hours, as users surf from home computers rather than from work machines, which typically run Microsoft's IE.

"I expect Firefox and Safari to go up in December, too," said Vizzaccarro, citing the higher-than-average number of at-home days for most people this month. Some shops and employers are making it mandatory that the employees take weeks off this time 'round, instead of a few days.
