Microsoft has invited the Firefox guys up to Redmond to test Firefox and Thunderbird on Vista to ensure compatibility. The move isn’t entirely unexpected, after all, Firefox has been steadily eating into Internet Explorer’s market share ever since it was released.
It isn’t a wholly benevolent move, however. Microsoft is making sure all the big applications run smoothly on Vista because if they don’t, people won’t upgrade from XP. Microsoft is seeking out big developers now in a big effort to get all the major programs tested.
Previously Microsoft had focused exlusively on commercial developers but Sam Ramji, Director of the Open Source Software Lab at Microsoft posted on the mozilla.dev.planning newsgroup in an effort to get the ball rolling.
