Dont worry. FireFox is not going away. But it is transforming into something that the other browsers are not.

FireFox is a non profit, aka not for profit, organization. And it is being funded by the generousity of the wealthy and organizations like the Ford Foundation.

So FireFox is not designed/engineered to make money, aka profits. But the other browsers are and do make money by spying on your internet activities and tracking you. This information is then shared and shared and shared by the greedy corporations.

As such, FF is being designed to protect your privacy and your money. So there are many sites that dont readily work with the newly engineered FF. The issues can be the caused by FF blocking sneaky websites. Or it can be do to webpage designs that are viewable on money making browsers but not on FF.

But in time, things will improve especially since Apple has also announced a war on information pirates.

In the meantime, do not worry. FireFox is here to stay. If you have any issues with FF, we are here for helping you. But keep in mind, that FF is a work in progress and there are new things that are being implemented but do not always work well for 100% of the users.

In regards to that IT specialist that caused you a sleepless night? Just say "Really? Thats interesting. You're truly a genius. Thanks"  :-)
