I agree with you. I went back to Chrome because I am invest in Google's ecosystem obviously and it just works better but I didn't agree with what you're talking about. I also increase the screen display with to about 600 DPI so that I have desktop tabbing in my Chrome browser.Samsung browser is nice with great features, but if you use Chrome on your computer, then Chrome is more convenient. The Samsung browser can sync with the Chrome bookmarks. But Chrome not only syncs in real time (because it uses your Google account) across devices, it also does autofill. It remembers your searches, user names, passwords, and credit card information across devices if you have that enabled. So you don't have to enter that information twice.
Maybe it's just me but Firefox for Android uses 200 mb of ram easily. I'm in short we have 4 gigs of RAM on the phone but still it's a Memory hog.Used Chrome for long –fast & fluid– but, as it became less good for desktop, I sought other options; Samsung’s is quite good, but I’ve found Firefox decent for Android, excellent for desktop, and very synchronizable.
