Adobe Flash
Some websites require Adobe Flash player to view their data, how can I view the data without downloading this to my Macbook? I am a new user of a MacBook.
MacBook Pro (Retina, 13-inch,Early 2015), iOS 10.13.5
If they require flash and you must have the content on those websites then you'll need to download it.
Be sure to only download it from the Official Adobe website:
Adobe Flash Player Install for all versions
Also, be sure when you update it you only do that from Official Adobe website or from within your System Preferences > Flash player > Check for Updates.
