A study of nearly 96,000 websites carried out during the week of July 2 to July 8 found that FF had 27.8% market share across Eastern and Western Europe, IE had 66.5%, with other browsers including Safari and Opera making up the remaining 5.7%. The July market share represents a massive 3.7% rise since a similar survey in March.
A particularly worrying sign for Microsoft is that in some key European markets FF is threatening to overtake IE as the market leading browser. In Slovenia (47.9%) and Finland (45.4%) FF usage has reached parity with IE, while in Germany, Poland, Hungary, Czech Republic, Slovakia, Croatia and Ireland, FF has either reached or is nearly at 40% market share.
Countries where FF market share has now reached 30% or more include, Austria, Greece, Romania, Bulgaria, Estonia and Latvia.
Strong gains for FF were also reported in France, Sweden and Switzerland where in all three countries FF is now approaching 25% market share.
