I use Firefox on a day to day basis and generally build applications which work in Chrome and Firefox. They used to work well with EdgeHTML too. I've run into cases in the past where basic SVG rendering with an feColorMatrix filter doesn't work properly in Safari and looks like garbage .. but works fine in Firefox and Chrome. I've run into lack of support for HTML elements that every other modern browser vendor supports. I still can't believe there's no proper input[type=date] support on desktop. Away from desktop, I've also run into Mobile Safari failing to properly calculate the height of <iframe> elements, not supporting background-attachment: fixed and localStorage failing unintuitively in incognito mode. Safari is absolutely the browser that gives me the most issues; I'd call it the new IE.
