I've been running firefox on my laptop for the last year, with Chrome on my desktop, as a way to head-to-head them. For folks contemplating the switch, it hasn't been bad at all. Some better, some worse, but overall I rarely notice major differences except for a very small handful of sites that won't work with FF.
And I still have all of my uBlock origin happiness. :)
