How to destroy the evil BING search engine for good?

[Carly]

No matter what I do, my computer reverts to Bing. Before you say to use Google Chrome, that is not an option. Whenever I use Chrome, it crashes within an hour of opening it. This isn't good for me and my prolonged computer use.

I've changed it in settings, and it'll stay as Google for a month or two, but the next time I update anything on my laptop, it switches back to Bing.

It's not only my laptop, however. Every computer in my house has slowly started to catch the Bing. It's spreading.

How do I get rid of it for good, while still using Firefox? I cannot stand to open my browser and see this evil website one more time.

I am morally against Bing. I feel that it is evil and attempting to take over the internet. It clearly wants a monopoly search engine. It's trying to kick all other search engines out of the picture. I do not like Bing. You cannot "bing" something. You can "google" something. Bing is just not THE search engine, no matter how hard it tries.

Please, help, before it infects my whole town.
