Here is what you said but in English:

I don't know if you have noticed: under the same operating system and the same network environment, Firefox's access speed is perceptibly slower than Chrome's.

Firefox also updates very frequently, but Firefox's own updates are also very slow to download. I don't know what's going on in between a 10MB update and I don't know what's going on or any special settings for a particular browser, but it's unbearable on my computers.

Can't the official developers really find a way to optimize it? In the long run, it's obvious that Firefox's market share has hit rock bottom!

We don't want to dominate the browser market, we want to have more choices, but you have to fight for yourself!
