Very interesting. When Firefox 4 was launched, it was 12MB. When Australis was launched it was 28MB. Now, Firefox 33 is 35MB. That's almost a 200% increase. I did an A/B test last year when the installer was 22MB and there was a strong correlation between average internet speed in a specific region of the world and install-rate of Firefox. If world-wide internet speeds are not increasing faster than the growth of the installer, it could be having a negative impact on adoption of the product. By how much? No one is for sure as the A/B test was just testing the current size of Firefox and one 3MB bigger. The conclusion of the test was that 22mB vs 25MB didn't have a statistical difference in conversion rate, but now a year later, we are more than 10MB bigger.
It looks like everyone provided helpful information and this is a great start. I am going to work on creating a document to help to quantify what are the drivers in the growth of the installer. After that we can decide what does this tell us and if the growth of the installer has negative impacts. Thanks everyone!
