I use FF as my browser and all of a sudden they are pushing out different versions like it's going out of style. I used FF 2 for ever, then 3 came out and it was roughly two years before 4 came out. When 4 finally did come out, it was a major upgrade and everyone that used FF was looking forward to it. Two months later, version 5 came out and I thought it was a major security issue to warrant a complete version number and that version 4 was hosed somehow. I've now read that version 6 will be out this week and that version 7 by the end of the year.
My question is, why the new version numbers all of a sudden? In one year, they will have upgraded four different versions. Are the changes that different to warrant such a version change?
I didn't find the right solution from the internet.
