I've seen similar issues simply by using Linux as my main desktop... some sites just won't work because of it, or seem to filter out "Linux" in the user agent. Which kinda sucks.
Web services could have at least one developer using Firefox and another one using Safari. I'm the one with Firefox for my customers. Their web apps work with at least Chrome and Firefox. Safari is on them, if they have a Mac. Nobody ever complained.
If Safari and Firefox had the exact same lists of sites and fixes I might agree, but they don't.
Just ditch Chrome and then the website owners see shrinking traffic.
Oh, I thought Chrome did have a similar list - maybe I got confused with WebKit. This very site has one quirk: https://github.com/WebKit/WebKit/blob/25738effd8eeca9b8d15e4...
