Exactly my same feeling. And what's worse, is that I don't really know what those entries (.js files) can do. Can they exec code whenever they want? Or every hour? Or every minute? Can they see what I do? Can they call home (and know my IP even if I'm not visiting those websites)? Why do I have to read a technical spec to learn about this?
One thing I used to love about websites is that I knew once I closed the tab the site was gone forever and it was not allowed to execute any more code. That was heaven.
But now with web workers and service workers and god knows what else, I feel like I've lost that security, and that makes me uneasy. It's a security and a privacy issue.
I know I can disable all that stuff in about:config but how do I know they haven't invented some other new technology in the past months that I should be aware of?
>To quote this excellent article[1]: "the default setting of the Canadian male: a dull but stern dad, who, under a facade of apparent normalcy and common sense, conceals a reserve of barely contained hostility toward anyone who might rock the boat. To these types, those who make a fuss are bothersome and ignorant at best, and probably dangerous and destructive too."
Just being a conservative or a right-winger is bothersome and ignorant and dangerous and destructive and lots of bad things. What a way of seeing the world. :-)
Gmail won because it fixed the biggest pain points with HTML email and spam. And so many years later nobody has come even close. That's not their fault.
>The “extinguish” with GMail is also well underway - it’s infamous for having an extremely strict spam filter for incoming emails from people who run personal or niche mail servers
And thank God for that. That's why their antispam is sooo good.
