Which browser are you using? Which browser are you targeting as the base for your web apps?
"By Net Application's tally, IE6 has lost 3.2 percentage points in the last three months, and IE7 has fallen 4.2 points; IE8, however, has gained only 4.2 percentage points in the same period.
... Last month, Firefox added about 0.7 of a percentage point to its share, finishing November with 24.7 percent. Chrome grew by 0.4 of a percentage point and Opera increased by 0.1 of a percentage point, to end the month at 3.9 and 2.3 percent, respectively. All three browser's shares were records.
Most notable were the gains by Firefox and Chrome. Firefox neared the 25 percent milestone, which it should pass this month, and Google's browser closed in on Apple's Safari, which lost market share for the first time since last April. If the trend from the past three months continues, Chrome will pass Safari and take the No. 3 browser spot in January 2010.
Chrome'ss growth is impressive, in part because it's been fueled almost exclusively by the Windows version, the only edition that has made it out of developer and beta testing. Google plans to issue a beta of the Mac version this month, which could add even more to its momentum going into the new year."
