Some of us do use different browsers for different things; I use Safari as my "general" browser, Chrome for video streaming and Google things, Chrome Canary for my business, and Firefox for my "personal" browsing.
I use Google Chrome. uBlock Origin is able to block ads on Youtube unlike the uBlock for Safari. I will never install or download another Mozilla project ever again.
And inefficient for memory?Would it be a little bit complex? Use multiple browsers for multiple purposes?
I'm currently using Safari on the latest public beta, and I like how smooth it seems compared to Chrome. Scrolling is so much less of a drag compared to Chrome for me, and you can't forget to mention the battery life Safari gives versus Chrome (Obviously). What browser are you using?
