New browser market share data shows that both Internet Explorer and Firefox lost ground in April. While Microsoft and Mozilla trumpet their latest browsers, publicly trade jabs, and beat their chests at one another, Chrome and Safari are quietly gaining market share.

Firefox declined by nearly two tenths of a percentage point overall, while Internet Explorer fell just over eight tenths of a percentage point to a new low of 55.11 percent. IE still has two and a half times the market share of its closest competitor–Firefox–but it has been losing ground slowly, but surely over the past year or two.
