>I can't get the tone of the article or how I'm supposed to feel about it

It's a tech article. What do you expect to feel while reading it?

The author uses a really excited tone and frequent questions like You know what? Guess what? Wow! Boom! Exaggeration obviously, but I like to connect emotionally with the author of whatever I am reading. You can understand a lot more that way than words can convey. I was not able to keep up with such an enthusiastic post that's all.

I suppose the author was expecting that people who read the article already knew what it's all about (i.e. the context) - switching browsers because of manifest version changes made by Google, and some "concerns" that people have about Firefox compared to Chrome. But that part is conveyed in the first two sentences of the article.

In the end, he is just "excited" to help people switch to Firefox, that's all.

> This is really hard to read.

I am old and I agree.

It is full of things that break the flow of reading like asking a hypothetical question to the reader and following it up with a plosive like 'BOOM!', or inserting useless conversational stops like like 'sure,' 'But...', and '...Nope!'.

Makes it sound/feel like an excited toddler is desperate to tell you something, but cant really get to the point.

Exactly, maybe we are jaded. I like how excited these people are. Even if I can't relate.
