There's no reason you should be using Chrome. Using Chrome:
Means you consent to spyware (along with everyone else you interact with)
Allows Google to continue dictating web standards
Is a resource hog
If you haven't already, I highly recommend reading this comic about the dangers of Chrome: https://contrachrome.com/
If you need to absolutely use a Chromium-based browser, at least use Brave (just for that site).
Not-so-fun fact from the comic Contra Chrome: Google Chrome's URL bar is called the "omnibox." The name is derived from the Latin word "omnis," meaning "everything."
When you type into the omnibox, it's sent to Google's servers and added to your profile forever.
First and foremost I abandoned Chrome for the 3rd reason and haven't looked back. One of the largest corporations in the world can't make a web browser that doesn't use an obscene amount of ram to open 3 tabs at once :0
"Google is pointing out issues with my site performance. It's forcing me to inspect what I can improve. I finally removed google analytics and mobile performance jumped from 70 to 96."
I think that should tell you everything you need to know about how bloated Google is.
Some websites just don't work in Firefox, though. This is more of a fault of the devs, they've made websites that were only tested in and only work in Chromium, but it's the nature of things occassionally.
