Hi Arya! Typically if I was building something like this, I'd probably use a JS extension - but I like a good challenge, so I've found a way to do it that doesn't use any JS. This solution uses the User Agent string, which has its own problems (not least of which: Google is working to phase them out in Chrome), but in any case: Step 1: Data Layer Variables UDO Variable: is_safari , to hold the true/false state: JS Variable: navigator.userAgent , to read the User Agent string from the browser: Step 2: Extensions Set Data Values extension scoped to Before Load Rules, set is_safari to false - this provides a default state: Another Set Data Values extension, also scoped to Before Load Rules (but run after the previous extension), set is_safari to true when the User Agent string contains the word Safari. There are a bunch of conditions here, owing to the way various non-Safari browsers set things up: In case those conditions are hard to read, here they are in order: User Agent is defined And: User Agent contains (ignore case) "Safari" And: User Agent does not contain (ignore case) "Chrome" And: User Agent does not contain (ignore case) "Android" And: User Agent does not contain (ignore case) "CriOS" And: User Agent does not contain (ignore case) "FxiOS" There may be other non-Safari User Agents out there that contain Safari and also something else, but the above should catch most of them (it seems most non-Safari browsers use the Safari + Chrome combination). Hope this is helpful! - zac. ... View more
