Mozilla says some 50 million copies of Firefox have now been downloaded since it was made available last year.

I've seen this statement on a number of Firefox threads. I downloaded Firefox 1.0 many months ago... but I've also downloaded versions 1.1 and 1.2. I see now that the current download is version 1.4. So am I led to assume that the current number of Firefox USERS is a number substantially less than 50 million?

Hmmmm......no idea.....I have also downloaded multiple times.

1.0.1, 1.0.2, and 1.0.4. Version 1.1 has not yet been released.

If history will be a guide, most people do not download multiple times. This is why there are people who are still using Netscape Navigator 4.7. I don't think there is any doubt that Firefox is causing some damage to the IE numbers. A recent CNN article says that IE is now less that 90% with firefox taking almost 7% of the browser market. And more importantly, Microsoft released a popup blocker on XP SP2, and will have a browser with tabs when they release IE 7. If Microsoft thinks there is competition (by starting up browser work for the first time in about four years), Firefox is being effective.
