Although Firefox and Internet Explorer are competing for the market share, they do respect each other and as a tradition Microsoft always send a cake to Mozilla whenever they ship an major version of Firefox.

In continuation of the tradition, the Internet Explorer team has sent a cake to Mozilla for shipping Firefox 5 yet again. Here is the picture of the cake that Damon Sicore, VP of Engineering at Mozilla, posted on Twitter:

With Firefox following Chrome’s version numbering system and Firefox 6 and 7 scheduled for release this year, I guess the guys at Mozilla will be getting a lot of cakes from Microsoft.
